What type of book file do I need?


Choosing the right e-book format for your reading device.

157 words 1 minute read

E-books come in two main types of file: ePub and Mobi.

If you buy your e-books direct from the same company that made your reading device, such as Amazon, Apple, or Kobo, you never usually have to worry about which type of file you should download. They will usually automatically appear on your e-reader, mobile app, or tablet after you've bought them.

But if you want to buy e-books from independent bookshops you'll need to know what format suits your device. Many independent shops will provide a selection of file types with every purchase, others will ask you to choose one particular format.

You'll usually have a choice between ePub or Mobi.
