Book formats

The primary formats for FBReader are ePub and fb2. For a comprehesive list, please refer to our table of supported and unsupported formats.

FBReader can open ePubs protected with Readium LCP. There are various DRM solutions for ebooks, but Readium LCP is the one supported by FBReader.

“Kindle format” is also known as mobipocket. FBReader opens *.mobi but does not understand their DRM-protection. That means FBReader works with unprotected Kindle books only.
