File formats


ePub files can be read on most e-readers including the Barnes & Noble Nook, Blackberry Playbook, Apple’s iBooks software (on iPhone, iPad and iPod Touch), Kobo, Sony Reader and more. You can use a variety of software to read ePub files including the free Adobe Digital Editions app.


mobi files can be read on the Kindle, Mobipocket Reader, Calibre and Stanza desktop amongst others. Many smartphones also support mobi files. Amazon’s Kindle software is available for most hardware.

Calibre e-reader software will read most types of files including ePub, mobi and prc, and is available for Windows, Mac and Linux.

If you want to transfer your mobi file to a Kindle, please seeĀ these instructions.


prc files are equivalent to mobi files. If you have a prc file but your device only supports mobi, just change the file extension from .prc to .mobi (see below).

File extensions

A file extension is the part of a filename after the . e.g. .txt in file.txt. If the extension is missing your computer will not know which program to use to open the file.

Some operating systems hide the extension of a file by default. To show them, try this for OS X , and this for Windows.

If your device says it cannot recognise the eBook file, please check it is in the right format for your device and that the file extension is present.

If your ebook files do not show an extension or have an extension which is not .epub or .mobi, and your software cannot recognize or open the files, try renaming the file with .epub or .mobi as the extension, as this often enables the file to be readable.
