FBReader SDK

The SDK is a library that allows building an ebook reader based on FBReader engine. We use the engine in FBReader, the app with millions installs on Android and iOS. If you want to test how your files look in the engine, please install FBReader.

The library includes rendering engine for text formats, i.e. ePub, fb2, mobi, etc. It does not include PDF renderer.

The library distributed in binary form. If you are interested in the source code license, contact us via email.
