FBReader

What is FBReader

FBReader is a popular (30+ million installs) ebook reader. Works on iOS, Android, Windows, Mac OS, and Linux.
FBReader uses its own book parser and rendering engine. The engine is lightweight, fast, and highly customisable.
FBReader supports many ebook formats, including ePub, mobi, fb2, HTML, RTF, plain text. The primary formats are ePub and fb2.
FBReader is not open-source since 2015. For developers, we offer FBReader SDK: a library that allows creating own ebook readers.

Get FBReader App

For Android devices, you can choose the stable version or beta of the upcoming new release. The app is available on Google Play, on Huawei AppGallery, and directly from our site.
FBReader for iPhone and iPad is downloadable on the AppStore.
In late 2021, we resumed Linux, Windows, and Mac OS development. Version for Linux is available for the public via the Snap Store. Windows app is published on the Microsoft Store. FBReader for Mac is installable from the Mac App Store.
If you are looking for the app for another platform, please check the “FBReader” menu item on the top of the page.

If you want to create your own ebook reader on the FBReader engine, use FBReader SDK.
The SDK is currently available for Android and iOS.
The SDK for other platforms might be available by request. Please, contact us via email.
The SDK includes the parser and rendering engine for text formats, i.e. ePub, fb2, mobi, etc. It does not support PDFs.
You can download the SDK and develop your app for free. If you decide to release the app, you have to buy the SDK key that removes warnings and unlocks all the features.
The price starts from £800 for a single key.
You pay once and have access to all upcoming updates.
