What is the format of books for iPhone

What are the formats of e-books

ePub is the recommended format for e-books. The layout is floating, i.e. adapts to the size of the reader’s screen. Supported by almost all mobile devices, tablets and readers.

mobi. format for reading books on Kindle devices.

PDF is a fixed layout format, the pages correspond to a printed book. Suitable for reading on computers and large screens.

PDF (spread or spreads) is a format with a fixed layout, written in spreads (this is how some creative and children’s books do, in which there are many illustrations for a spread). For example:

format, books, iphone

fb2. format with floating layout, suitable for readers; on other devices fb2 is also played.

In what format to download books on iPhone

The native e-book formats for the iPhone are the iBooks app formats.

So there are two forms that can be used for iPhone:

  • EPub (Electronic Publication).
  • PDF (Portable Document Format).

In the iBooks program, books look great, they turn over. The size of the font can be made larger right in the process of reading.

Which e-book format is better to choose and which application is better to read

When choosing an application for reading, keep in mind that it is not only about how beautifully the pages are flipped in it and how many colors there are for bookmarks, but also how the application interprets the files. Some applications, for example, ignore some of the tags and symbols (Stanza, Tucan applications do not understand the non-breaking space character, which is why the reader receives a book with stuck together prepositions).

For devices using electronic ink (they are also readers, they are e-books; examples of devices: Book, Bookeen Cybook, Digma and others), ePub and fb2 are suitable (for older models).

The main electronic format is ePub. It conveys the most formatting elements among floating-type formats.

Fb2 is a format that simplifies a lot, therefore it is suitable for devices with disabilities to display books (some devices on e-ink).

If you like fixed layout. read PDF anywhere.

  • If you have an iOS device, it is better to read in ePub format in the native iBooks application (available on all devices, synchronized).
  • Android devices. ePub in Google Play Books or Mantano Reader apps.
  • Windows Phone devices. ePub, e.g. in the Bookviser Reader app.


But you can read on the iPhone in another format FB2 (Fiction Book). This is a specialized format for viewing books. Only for this format the iBooks program will not work. You will need “Aichitalka”.

You can upload no more than 100 of your books and each book should not exceed 5 MB. these are the terms of use.

All books loaded into the memory of the reader, regardless of the source, are automatically sorted and organized on a beautifully designed virtual bookshelf.


This type of markup assumes that all elements have a clearly fixed position on the page with a clearly specified size. This markup has a format that most closely resembles a physical medium, such as a page of a regular paper book. Everything in its place and no adaptation. On devices, adaptation most often looks like scaling with all of this ensuing consequences. What looks acceptable on a computer screen is already too small on a tablet, and on a smartphone screen you cannot see it at all. Well, playing with zooming in and out turns into torture for the reader.

An example of displaying fixed markup

This format is suitable when you know for sure that your work will be read on a medium with a specific size, under which your work will be laid out. Initially, it is assumed that this markup was developed for further printing of the work, therefore it indicates the size and format of the future medium. We do not recommend using this markup for e-books, as it limits the reading area of ​​books to devices with a certain screen size.

The most common digital representation of this markup is PDF, but EPUB also supports it.

We decided to tabulate popular formats and show support for various markup inside them.

Reflowable Fixed-layout format
ePub perfect support good support since version 3.0
PDF not ideal for rigid marking
FB2 complete not
TXT complete not
MOBI complete good

We figured out the layout. Now let’s take a look at the most exciting moment for authors. copyright.

About the FictionBook format

Popular under the name FB2. It is popular mainly in Russia and in the post-Soviet space, so you can safely call it a national format.

Nevertheless, this format contains logical markup, the book is divided into sections, which can be poems or prose. However, the format itself is very limited because not only there is no support for complex layout and formulas, but also banal things like bulleted lists.

There is an idea of ​​the FB3 format, an improved FB2, judging by the description, which is a clone of the ePub format. It uses a similar zip archive and separates files into description, text and pictures. Dmitry Gribov is intensively working on a new format and we hope that he will delight the authors with new opportunities.

This format is well suited for simple fiction written in Russian.

Choosing the best format for your e-book

Sometimes it seems that deciding on the format is quite difficult, there are so many of them and each has its own advantages. Many authors ask themselves the question: “How to choose a format for an e-book?” We conducted our analysis of the formats and found out which is the best format for ordinary books. We have carefully studied many formats, and considered them both from the point of view of the convenience of the reader and from the point of view of the convenience of the author. Let’s dive into the details a little and see what influenced our choice.

Reflowable markup

You can translate into Russian as fluid, adaptive or floating. Allows you to fit the contents of the book to the device screen, change the color and size of the font. Ideal for ordinary books with simple text. novels, poems, technical literature. Those. anything where clear image anchoring or complex visual presentation is not required.

This markup is not suitable for visual interactive books and children’s books with many illustrations, that is, those that require spatial referencing of graphics, various combinations of pictures and frames. By itself, the EPUB format allows you to create interactive books, but the responsive design of such books. this is real art.

Using this markup is ideal when you don’t know exactly where and how your book will be reproduced. Due to the flexibility of the layout, the book will be correctly displayed on almost any device, from a computer to any smart watch. Plus, this markup is perfect for people with disabilities.

Why ePub is the best format?

During the development of our services, we studied some technical nuances that affect the appearance and work with an e-book.

Let’s start with the simplest thing. managing the display of the book. Those. the ability for the reader to change the font size and page orientation. EPUB adapts perfectly to device screen size or font size changes. I would like to note that the specification states that in fact the format supports 2 layout modes. the first (reflowable), when you can change these parameters, and the second (fixed-layout), when you can clearly indicate what is where.

Let’s consider the layout modes in more detail.

IBooks for iPhone book formats. ePub

Given this trend, the developers have found an opportunity to use a different format for books for the iPad. There are many applications in the App Store for this purpose, we will tell you about the most popular.

Types of formats and programs for reading

Considering that the format of books for iPad is diverse, it is important to choose a special application for opening, the so-called Reader. Below we will consider the most convenient types of formats.

One of the most suitable for an Apple device is the iPad ePub book format. It is considered “native” for the device, and you can open files with this extension using iBooks. In recent versions of iOS, this utility is usually bundled with the mobile OS.

Before the release of iOS 8, the program was not included in the OS, but it can be easily found and downloaded from the App Store.

IBooks has convenient bookmarks, and you can also synchronize with all your apple devices via iCloud. Among the shortcomings, one can single out only that there is no synchronization with alternative platforms.

If you are interested in the most common book format for iPad and other devices, then definitely PDF. Files with this extension can be read both on a personal computer and on a phone or tablet. Documents have high-quality formatting, vivid images, etc. You can also read PDF files through iBooks.

Features of e-books with this extension:

  • the best format to store and view logs;
  • wide range of Reader applications;
  • PDF files can be easily scaled to fit different screen sizes.

Besides iBooks, GoodReader is a great application for opening PDF documents. With this utility, you can quickly download documentation from attachments to your mail, use WebDAV and FTP. Using the Good Reader engine, you can effortlessly process massive documents with a volume of several hundred megabytes. Disadvantage. the program is paid, the price in the App Store is 4.99 USD.

The FB2 book format on the iPad is best known only on mobile devices. iBooks does not open documentation with such an extension, for this it is better to use KyBook.

  • Supports ePub, FB2, FBZ, PDF, TXT, CHM, AudioBook and ComicBook formats;
  • works with archived documentation with ZIP and RAR extensions;
  • gives access to a huge collection of free books;
  • provides the ability to flexibly adjust the display of text;
  • simple internal navigation through the document using content, bookmarks and notes;
  • has built-in support for GoogleBooks, GoogleDrive, Dropbox, OneDrive and Yandex.Disk.

If you are interested in what format of books the iPad supports for easy viewing of scientific literature, then, of course, DjVu. In fact, electronic files with this extension are ordinary images (most often scanned books, technical manuals, etc.). DjVu is often used for textbooks and various technical documentation. The best way to view electronic documents of this kind is through the DjVu Reader. Among the features of the program are:

  • compatibility with popular archive formats (ZIP, RAR, etc.);
  • the presence of speech synthesis;
  • convenient navigation.

This is the simplest type of electronic documents. On the iPad, you can use many programs to open texts with this extension. Among the disadvantages of TXT files. there are not many opportunities for regulating text documentation, there are no illustrations and beautiful markup.

Alternative way

Despite the fact that the format for iPad e-books is diverse, we will bring to your attention one more convenient option for reading documentation on an apple tablet. open it through The eBook Converter. This application converts any electronic document from iBooks to formats such as the aforementioned ePub, PDF, FB2, as well as MOBI, AZV, Lit, LFR and others. The price of the converter in the App Store is 2.99 USD.

In the App Store, you can find even more software products for reading, and in which format to download books for iPad is up to the user.

Documents, charts, contracts and other technical files are often downloaded in PDF format. After all, it will not work normally to read and flip through a book in this form.

Fb2 format for Apple

Fb2 is considered the main alternative to the formats described above, but for it you need to download the reader separately. Since iBooks does not support this formatting for files. We advise you to download Aichitalka, which has a similar appearance, management and navigation.

There is another way out: you can convert the Fb2 format to ePub through an online service or built-in program. But it’s better to download several e-readers for reading books in different formats, so that you are ready for any situation.

What else do we recommend?

If we figured out the question of which format of books on the iPhone is more suitable, then with applications it is not completely. If you do not like the ones described above, then you can try these:
