What book formats are suitable for Android devices. E-books

Electronic books (readers, readers) have long become common devices for a wide range of users. Their advantages: accessibility of content (you can download the necessary book from the Internet in a matter of minutes), an E-ink screen that does not damage your eyesight, the ability to have a collection of thousands of books in the reader, long work on a single charge, settings for font type and size. Not long ago, e-books with backlit screens appeared - they allow you to read in complete darkness. In general, the advantages of readers can be listed for a very long time.

However, when getting acquainted with e-readers, users often have one problem. People who decide to purchase a reader for the first time, when faced with the concept of “electronic book formats,” often do not understand what we are talking about. The problem is especially relevant for beginners, to whom the abbreviations "FB2", "EPUB" or "MOBI" mean absolutely nothing.

So-called formats are various types of electronic text files that are supported (played) by one or another. IN electronic libraries The Internet often offers a large set of file types: FB2, EPUB, MOBI, PDF, DOC, RTF, TXT and others. The choice is wide, and this poses certain challenges for beginners. We will describe the main formats of e-books, tell you how they differ from each other, which readers are supported, and which format is better to choose if you have a multi-format reader that reads all formats.

Varieties of formats

1. FB2 (FictionBook)- an e-book format that was created by a group of Russian developers. Books in this file type have a structured appearance (that is, they contain a breakdown by chapter, content, illustrations, cover). In addition, this standard stores information about the file (so-called tags: author, title, genre), which is read by the reader and allows the user to conveniently sort files on the device. This type of file takes up a small amount of space, can be archived, and is also easily converted into other formats. Among the features: due to the fact that the format was originally developed for the Cyrillic alphabet, texts in Russian in FB2 have word hyphens.

The format was originally designed for Russian users, and it is practically not used abroad. That is why FB2 is not supported by the world's popular e-reader manufacturers - Amazon and Barnes & Noble. But this is the main file format for e-readers popular in Russia from Pocketbook, Onyx and Wexler. In addition, Sony readers now support FB2 - after entering the Russian market, the company has developed official firmware for the reader, which allows you to read books in FB2.

2. EPUB (Electronic PUBlication)- the most popular in the world electronic format for readers. Barnes & Noble and Sony readers work with it. In terms of layout structure, this type of file resembles an archived web page containing text, graphics, embedded fonts, and illustrations.

In addition to Western brands, the EPUB format is supported by models from manufacturers focused on the Russian market (Pocketbook, Onyx, Wexler) due to the rapid growth of popularity in our country. In addition, this e-book standard is used by iPhone and . Apple's proprietary iBooks reader supports EPUB.

3. MOBI- format of e-book readers. Gaining popularity in Russian online libraries as Kindle becomes more popular in Russia. Other readers support this format “for show”. MOBI is similar in properties to EPUB. Amazon recently introduced another electronic text format, Kindle Format 8 or KF8 (it features richer formatting), with the clarification that Amazon readers new and old will continue to support MOBI.

4. TXT- format of simple text documents. You can convert text from another format to TXT with a simple copy-paste action. Despite the fact that this type of file is supported by almost all e-readers and takes up very little memory space, we would not recommend reading books in it on e-readers. TXT lacks formatting, markup, hyphenation, and alignment. It is suitable for short text notes, but not for full-fledged e-books.

5. PDF (Portable Document Format)- an electronic document format created by Adobe Systems. Inconvenient for use on readers for a number of reasons. Firstly, files in this format are very bulky, as they are designed for the power of a computer, and open quite slowly on e-readers. Secondly, if the file is not specifically designed for the screen of a 6-inch reader, which has a format similar to an A6 paper sheet, then reading an A4 PDF on it (and most PDF files are presented exactly in the size of a standard paper sheet) will be very difficult. In PDF, you can only increase the scale, but not the font size, which means that only some part of the page will be able to fit on the screen. You will have to read the pages in parts, and this is very inconvenient.

For PDF reader adapted, the screen size of which allows you to reproduce the page on a scale large enough for comfortable reading.

6. DJVU- a format designed for storing scanned documents - books, articles, manuscripts. A book in DJVU is actually a collection of scanned pages. In terms of reading comfort on 6-inch readers, everything is similar to the story with PDF. You won't increase the font size, just the scale. When zooming, the page will extend beyond the screen, and you will have to constantly move the area of ​​the enlarged text to read - there is no need to talk about comfortable reading. To read DJVU, choose readers with a 9-inch screen. However, even on 9-inch readers, the ability to conveniently read DJVU depends on how well the book presented in this format is scanned.

7. LRF- formerly a proprietary format of Sony readers. On new models (starting with PRS-T1) it is no longer used, as it has given way to EPUB. Converts very poorly to other file types. Despite the fact that it is still presented in some libraries, it is recommended to use it exclusively for owners of older Sony models.

8. RTF (Rich Text Format)- format for storing text documents. Belongs to the category of “computer”, not “book”. Reading in RTF on readers is not very convenient - these are large files, and the speed of the reader is reduced by an order of magnitude.

9. DOC(and DOCX) - text Microsoft documents Office. These formats are supported by quite a lot of readers, but specifically for reading documents, not books. Large files in this format can be large in size and difficult to work with on readers. It is better to convert multi-page books in DOC to FB2 or EPUB.

We have listed the main formats of e-books. We will not consider the completely exotic types of files that are sometimes found on the Internet, but rather decide which of the above formats is most convenient for reading books on electronic readers.

Which e-book format to choose

If you have an ereader that supports all formats, then opt for certain type file, based on a number of factors. Let's say you buy your first e-book, and you don't have a pre-collected collection of books, for example, in FB2. In this case, choose the file format that is best reproduced by your reader. Traditional “book” formats EPUB or FB2 are more preferable and convenient for the reader (and for the user) than “computer” PDF, TXT, DOC, DOCX and RTF.

In the case of 9-inch readers and the need to read DJVU and PDF, all other things being equal, we advise you to give preference to the latter, since PDF is a more modern format, and books in DJVU are often of poor quality.

From the point of view of ease of use, the advantages of “book” formats are obvious: EPUB, FB2 or MOBI look visually better in the menu of your reader (book covers are displayed), they are more convenient to sort (there are tags: author, title, genre), they take up much less memory space and speed of the reader with such formats will be significantly higher.

Do I need support for all formats?

In our opinion, it is not at all necessary to choose an all-format reader. Many users who have ereaders that support all formats download books in one or two file types. All e-readers (including multi-format ones), one way or another, have a main format, and in the end you won’t exchange for others. For Pocketbook, Onyx and Wexler the main formats are FB2 or EPUB, for Barnes & Noble () and Sony - EPUB, for Kindle - MOBI.

In the case of Amazon and Barnes & Noble readers, if necessary book turns out to be in a format that these readers do not support, you can use a converter (for example, Caliber). This is a program that is installed on your computer and allows you to convert the same FB2 to MOBI or EPUB in a matter of minutes.

Reading books in the reader’s native format is better than using those installed on the reader additional programs. Our advice: take a few minutes to convert a book, for example, from RTF to EPUB using the Caliber converter. This is more convenient than reading it “in the original” using an additionally installed program (on a Sony PRS-T1 or Kindle) or encountering slower operation of the device (for example, on Pocketbook readers).

Remember that the main thing is the ease of use of an e-book, and not the number of formats stated in its parameters.

Enjoy reading!

Hello, friends! You read books, right? And many of you, I’m sure, have long mastered e-books. This “brainchild” of technological progress is slowly replacing paper literature. Whether this is good or not, I will not judge in this article. The topic of this post is simpler - in what format is it most comfortable to read books on a smartphone.

I foresee objections to the fact that reading books on smartphones is inconvenient. The screen is too small, I agree. But thanks to the fact that the size of smartphones is increasing, this disadvantage is gradually disappearing. Reading books on smartphones has become the same commonplace, like reading on e-ink readers.Living proof that smartphones are and will be read is YotaPhone, which has a separate E-ink screen. YotaPhone 2 is expected to appear very soon.

Variety of formats

So, what is the best e-book format to choose for downloading to your smartphone? It is not so easy to answer this question straight away. Just look at the variety of formats that are now available in our world: PDF, FB2, TXT, DJVU, EPUB, etc. These acronyms look scary. But there’s no need to rack your brains here - just take it and deal with them once and for all. Let's get started.

In the first decade XXI century, when mobile phones were not as powerful as they are now, books in the JAVA programming language became widespread. Of course, it was possible to open text in TXT format, but only in relatively small sizes - no more than two megabytes.

Although at that time there were smartphones on such legendary operating systems as Symbian and Windows Mobile, they cost much more than ordinary mobile phones without operating systems. But these smartphones allowed you to open text files with the extensions TXT, DOC and some others.

For modern smartphones there is no problem opening a file of any format. Numerous applications have been developed for reading electronic books in formats such as EPUB, DOC, DOCX, PDF, DJVU, RTF, FB2. The list can be continued for a long time, but let’s choose the most optimal option for a smartphone among this “vinaigrette”.

If we take into account the size of the book, then the best option would be the regular TXT format (also called “notepad”). Such books will weigh quite a bit.

The following book formats are not recommended for reading e-books: DOC, DOCX, RTF. Such files weigh a lot. In addition, they are demanding on smartphone resources and cannot always display text correctly, displaying hieroglyphs on the screen. DOC type formats are created primarily for personal computers and are opened by special office programs.

The DJVU format is usually used to store technical books: reference books, textbooks, instructions. Books of this format are often simply scanned and look like a set of pictures without the ability to format the text. The same applies to PDF.

The most optimal format for e-books is FB2. It has many advantages over others:

1. Books weigh a little more than ordinary TXT.
2. You can view images , since there is support for illustrations.
3. It is possible to format text and view detailed information about the book : year of publication, file name, author's name, etc.
4. Navigation by page carried out easily .
5. There are built-in styles .

Thus, if you have a choice of several formats when downloading an e-book to your smartphone, feel free to choose FB2.

Human, book lover, strives to read anywhere and everywhere. That is why in last years Reading from e-readers or mobile phones has become so popular. Of course, we can talk as much as we want about the delights of the smell of a new paper book, about the pleasant moments in a bookstore, when choosing additions to your library, but the fact remains that in the everyday hustle and bustle of reading e-books is easier than carrying around the usual paper volumes. If you write and want your work to become convenient and accessible to readers, it is not enough to post texts on open resources; it would be nice to also attach file versions to them so that people can download your creation and evaluate it at their leisure.

Regardless of whether you are a reader, a writer, or a two-in-one, when downloading or uploading texts with files, you may encounter that your phone or reader does not support this format (or your readers complain that the files they can’t read this format). To understand why this happens, we have written for you a short explanation about what types of e-book formats there are, how they differ and what the advantages and disadvantages of each of them are.

Types of formats:

First, it should be noted that the most common e-book formats are: FB2, EPUB, MOBI, PDF, RTF, TXT, DOC/DOCX and DjVu. Naturally, when an uninitiated person is faced with such diversity, it is difficult to figure out what’s what and what format to choose for reading or converting your files.

Microsoft Windows, but, unfortunately, DOC/DOCX are not supported by most readers, and they may not always open on mobile phones, and reading books in TXT is very, very inconvenient.

However, let's talk about everything in order:

FB2 (FictionBook)

Advantages: One of the most common formats in the Russian-speaking segment of the Internet. It is convenient to structure a large document, divide it into chapters, etc. FB2 files take up little space and are easily converted to other formats.

Disadvantages: FB2 is a format developed in Russia. It is not supported by most readers and is unknown worldwide. It opens only on devices with Russian firmware and is alien to branded readers that are leading around the world: Sony, Amazon Kindle, Barnes&Noble, Kobo, etc. Yes, you can bet that it opens on Sony FB2, but the official firmware that allows you to open this format on Sony readers, was published only a couple of years ago and is not installed on all models. If we talk about selling your works on Amazon or iTunes, the answer is clear - FB2 is not suitable for international platforms.

PDF (Adobe Portable Document Format) and DjVu (pronounced “deja vu”) - we will not consider each separately and will combine them into one point.

Advantages: Both formats are used to store scanned books. PDF can create very colorful files. DjVu simply compresses files quite well, making them weigh less.

Disadvantages: PDF files are very bulky. If we are talking about scanning, then in any case, scanned books are inconvenient to read from the screen, since their quality leaves much to be desired, regardless of whether the scan is posted in PDF or DjVu.

Advantages: TXT opens on any reader. DOC/DOCX are well-known Microsoft Word formats.

Disadvantages: Reading books in TXT is terribly inconvenient, since it lacks text formatting (width alignment, paragraph wrapping, division into chapters, etc.). DOC/DOCX is supported by a very small number of reading devices.

RTF (Rich Text Format)

Advantages: Convenient and compact format for storing text files.

Disadvantages: It is extremely rarely supported by readers and mobile phones, tablets, etc.

Advantages: LRF is a special e-book format from Sony. MOBI book format for Amazon Kindle.

Disadvantages: Currently, Sony also supports the more popular e-book format - EPUB.

EPUB (Electronic PUBlishing)

Advantages: EPUB is the most common e-book format in the world. It has no recognition problems and allows you to create well-structured text with illustrations. This format is already an archive in itself, and therefore compact and does not require additional archivers.

As you can see, each of the formats mentioned above has its own advantages and disadvantages. For example, of course, the most “readable” format for e-books will be TXT, but reading books in this format is practically mocking your eyes. Such a text cannot be structured, it lacks paragraphs, chapters, it is impossible to insert illustrations, etc.

The most common and convenient format for reading e-books is EPUB. However, if we are talking about the form in which the author should post his work online, the most rational decision There will be a display in several formats at once. For example: EPUB (readable everywhere except Amazon Kindle) + MOBI (readable only on Amazon Kindle) + DOC/DOCX (for those who are used to reading from computers and laptops). Of course, as a bonus, you can post the text in FB2 format, to which the Russian-speaking audience is so accustomed, however, not all devices will open a file in this format.

And of course, at the end of this article and as an advertisement, we would like to inform you that a new Internet system, Booqla, has recently launched in the CIS, designed for convenient and, attention, free conversion of manuscripts into EPUB and MOBI formats. The site offers users from all over the world the conversion of their manuscripts into electronic format and provides assistance in the sale of e-books, but only free conversion of manuscripts will be available for the Russian-speaking audience.

You can evaluate the simplicity and convenience of the Booqla service for yourself by registering on

What is deja vu? No, this is not only a psychological state when it seems to you that you have already seen something similar, or have been in a similar situation. This is also the DjVu file format, a graphic format that is used primarily for saving and compressing scanned books containing color images and text. In the last few years, there has been a boom on the Internet, when books and magazines in this unusual format began to appear everywhere, and entire libraries were opened. What kind of format is this? What are its advantages or disadvantages, for example, over the PDF format? And how to view such files? This article will tell you about all this.

What is DjVu

12 years ago, AT&T Labs first announced the creation of a new graphics format called DjVu. The initial purpose of its creation was to maintain electronic document management. Despite the fact that the PDF format already existed, it was not satisfactory primarily due to the size of the finished files. To conduct internal document flow, companies needed a format that would be small in size and at the same time very good quality, especially good readability of the text and could convey all the details of the document (its texture, abrasions, damage, etc.).
However, gradually the new format began to penetrate the Internet, where it gradually began to occupy its niche, pushing aside the giant PDF. For Internet users with a small channel and limited traffic, this was an ideal option.
What is Deja Vu? It is a lossy graphics compression method that supports multi-page documents. Its peculiarity is that before compression the image is divided into two or three layers, text and pictures separately. Then these layers undergo initial compression, the pictures are compressed more, since the loss of their quality does not greatly affect the final result, the text is practically not compressed to ensure maximum quality. Next, the resulting result is compressed using new codecs – IW44 and JB2. IW44 uses wavevets, giving it a size/quality ratio two or more times better than the JPEG format used in PDF.

As a result, an ordinary full-color page with text with a resolution of 300 dots per inch (dpi) has an average size of 50 kb, which allows you to use documents in DjVu format in the internal document flow of companies and on the Internet.
MirSovetov considers it necessary to say separately about the text in DjVu documents. This format supports the ability to add a layer with recognized text (OCR). Despite certain difficulties and labor costs in its creation, as well as the fact that the presence of this layer increases the file size, it provides additional convenience for users. So, if there is an OCR layer, the text can be selected, copied and pasted into a text editor, or the text can be exported to a separate file. In this case, the text has no formatting, that is, when you paste it, for example, into Word, you will get a piece of heterogeneous text, often with various unnecessary elements (various icons, unreadable characters). Also, if there is recognized text, it is possible to search through the text of the document.
Let's summarize a little, calculate the advantages and disadvantages of the DjVu format and see what we can come up with.

Pros:

• the main advantage is, of course, the small size;
• with a small file size, good quality of images and especially text is maintained;
• Only the visible image is processed, which reduces the load on computer resource consumption, which is especially important for large files and for owners of weak machines;
• the ability to use the format for displaying literature and documents containing formulas, diagrams, tables, as well as historical documents, while preserving the texture of the scanned document;
• text remains clear even at high magnification.

Minuses:

• DjVu is lossy image compression. That is, some information is inevitably lost. This mainly applies to pictures.

DjVu now

Initially this format had open source, thanks to which it exists great amount free software to work with it. But in 2000, AT&T Labs transferred the rights to the format to LizardTech, which continued the path of promoting and developing DjVu, while already relying on commercial rails, offering its products for money.

In 2005, using DjVu technology, more than 4,000 issues of The New Yorker magazine over its 80 years of existence were converted into electronic form. They fit on 8 DVD discs.

Recently, DjVu has become very popular on the Internet. at a fast pace. Primarily due to the advantageous file size. But at the same time, many users have not yet learned how to sufficiently work with this type of compression. As a result, DjVu in most cases is significantly inferior to PDF.
A serious obstacle to the development of DjVu is the fact that PDF has been used in various fields for many years, and this format has become the standard for document management. Various user manuals and documents are distributed in PDF format. Nevertheless, new technology is progressing and gradually gaining its place in the market and in the hearts of Internet users.
And the latest news from the world of DjVu from MirSovetov. On July 1, 2008, Celartem Technology Inc., a provider of software solutions for storing, viewing and distributing multimedia materials, as well as the parent company of which LizardTech is a division, announced the creation of a new sales and management center for DjVu, which is located in Seattle, Washington. (USA). Accordingly, now the format is supported on the Internet not from the LizardTech company website (http://www.lizardtech.com), but from the Celartem Technology Inc. website. (http://www.celartem.com).

The world-famous project to create an inexpensive computer for African children - "One Laptop per Child" - also chose the DjVu format for use, which optimally meets the requirements of the project concept with its small size.

Possibility of working with DjVu format

What can we do when working with a document in DjVu format? Of course, everything depends on the specific program chosen, but there are some general features.
When working with the DjVu format you can:

• enlarge/reduce pages, adjust to page width/height. They can be turned over, placed two or four on the screen, flipped or scrolled using scrolling;
• work with text if the file contains a layer with recognized text (OCR). In this case, the text can be selected, copied and pasted in a text editor, and in this case you can also use the search in the text of the document;
• select individual parts of the page and copy to the clipboard;
• print the document or individual pages;
• make bookmarks, use hyperlinks, which leads to good navigation through the book;
• view the page in different modes (color, black and white, background, foreground). MirSovetov advises sometimes (for better text display) to switch from color mode to black and white. The text becomes clearer and brighter, but color pictures are not displayed.

Programs for viewing DjVu

Using what programs can you comfortably view books saved in this format? There are many viewers, we will briefly describe the advantages and disadvantages of some of the most common and most importantly free programs.

DjVu Browser Plug-in for Windows

Program page (English): http://www.celartem.com
Language: support for 10 languages ​​(Russian is not on this list, unfortunately)
Platform: Windows, Mac OS X, UNIX
Download: http://www.celartem.com/en/download/djvu.asp
Size: 5.6-7.4 MB (depending on the selected language)

Viewer from LizardTech, which is currently promoting the DjVu format. On the download page, you can choose to either install automatically, or download the file first and then install the program manually.
Standard set of functions. There are various viewing modes, zoom, printing and the ability to save pages in BMP format (for example, for later use in the FineReader program). Simple and convenient interface.
Individual parts of the page can be selected and copied as an image.
When working with a text layer, the search is not very convenient. Although it has a number of settings and successfully copes with its functions, it does not allow you to display all the results found in the form of a series of bookmarks. The results found must be viewed one at a time. But text selection works very well. Unlike other programs presented in the review, LizardTech’s creation copies text with the least amount of “garbage” (various icons, unreadable characters), so the result requires less editing costs in a text editor.
Like other programs presented in the review (except for DjVu FancyViewer) it has a useful function - scale by selection. We select this command and select part of the page - in the next moment it will be enlarged.
But the program is not without its shortcomings. There is a significant lack of scrolling within the document (it only works within each page separately), and there is not enough ability to make bookmarks.

WinDjView

Program page (Russian): http://windjview.sourceforge.net/ru/index.html
Platform: Windows 2000/XP/2003
Language: English (Russian, if you download an additional library)
Spreading: for free
Download: http://sourceforge.net/project/showfiles.php?group_id=114927
Size: 0.5 MB

A convenient, beautifully designed program, small in size and does not require installation. The default language is English. To set Russian, MirSovetov advises immediately downloading the additional library WinDjView-0.5-RU.dll from the download page and placing it in the same folder with the program. Then launch the viewer and select Russian from the menu.
There are various settings, including image correction (brightness, contrast, gamma)
When working with a text layer (OCR), you can select part of the text, copy it, perform a convenient search, and also export all the text to a separate file (txt). You can select part of the text (fill, frame), make bookmarks.
In addition to zooming by selection, WinDjView has another interesting feature related to the zoom mode. In this mode, by pressing the left mouse button, you can see an enlarged image of part of the page, as if you were looking at it under a magnifying glass.
Individual pages can be exported to BMP format.

STDU Viewer

Program page (English): http://www.stdutility.com/
Platform: Windows 2000/XP/2003/Vista
Language: English and Russian
Spreading: for free
Download: http://www.stdutility.com/stduviewer.html
Size: 1.5 MB

Another DjVu viewer. During installation, you can choose one of two languages: English or Russian. It works quickly and is small in size. A very useful feature is creating bookmarks and saving them in the document itself. And the main advantage over the other programs considered is that it supports, in addition to the DjVu format itself, viewing TIFF and PDF documents, thanks to which STDU Viewer also acts as an alternative to Adobe Reader.
This program provides the most comfortable work with text, naturally, in the presence of a text OCR layer. Here you can select a piece of text and copy it to the clipboard, followed by pasting it into a text file. To select all the text in a document, just select a small fragment at the beginning and click “End”. A very convenient search system with useful settings (case sensitive, only the whole word). The search result is displayed in the form of a list with bookmarks: the first column contains the page number, the second - a piece of text with the searched word. Double clicking on any of the bookmarks takes you to the desired page, the sentence with the searched word is highlighted in color.
There is also the ability to adjust the brightness, contrast and gamma of the image; this option is not very popular, but is extremely useful when viewing documents not in the most best quality. The downside is the inability to display individual image layers (color, black and white, foreground and background).
My choice is this program. The best combination of compactness, convenience and functionality. And of course – support for the Russian language!

DjVu FancyViewer

Program page: No
Platform: Windows
Language: English
Spreading: for free
Download: http://djvu-inf.narod.ru/djvubookmark.rar
Size: 1.5 MB

A simple and already outdated program that does not require installation. Nothing special, except for the colorful turning of pages in double-page mode. There are several options – it feels like you’re flipping through real book. There is indeed an inconvenience to this. The program displays the book all the time in a two-page format, so to make it convenient to read, you have to constantly use zoom.
