FBReader

Overview

FBReader is an ebook reader for desktop and mobile, with support for formats such as ePub, fb2, mobi, HTML, RTF and plain text. It is best suited to readers who keep books in several formats or move between supported devices. Its breadth is appealing, but the platform you use determines which features and limits apply.

Key features

FBReader opens ePub books protected with Readium LCP, giving readers another option for managing compatible protected titles alongside ordinary ebook and text files. Support varies by platform, so the same library may not offer the same capabilities everywhere.

The Book Network syncs book collections, reading positions, bookmarks and custom shelves across supported devices. Books are kept in the user's Google Drive space; metadata, covers and reading positions are kept on FBReader servers. FBReader says the service can upload new files to Drive and access files it created, but cannot access other Drive content. This is useful for readers who want their library and place in a book to follow them, with the trade-off that the service uses both Google Drive and FBReader's servers.

OPDS online book catalogues work on Android, Windows, macOS and Linux, but not on iOS at present. That makes FBReader a stronger fit for catalogue browsing on desktop and Android than on an iPhone or iPad. Android Premium adds PDF and comics support, Google and DeepL translation integration, and automatic reading aloud; those are meaningful additions for Android readers, but they do not extend to every platform.

FBReader's current code is closed source. On Android 10 and later, version 3.8 and newer uses Android's Storage Access Framework, which restricts folder access and can slow file operations. Android readers who regularly manage files in folders should factor that limitation into their choice. The maker offers a binary SDK for Android and iOS with a text-format rendering engine, but no PDF renderer. Support is directed through its FAQ and public Telegram group.

Pricing

FBReader is freemium, with free desktop, Android and iOS options. The Windows, macOS and Linux reader is free of charge; supported features and formats vary by platform. FBReader Free for Android costs nothing, though some features require Premium or separate plugins.

FBReader for iOS is free with in-app purchases. The free version is limited to ten books and disables online translation; the full version is a one-time fee, with no amount stated. This free tier suits a small library, but readers with more than ten books or who want online translation should expect to pay.

FBReader Premium for Android costs $14.99, paid once, billed as a $14.99 buy. It is a one-time purchase tied to a Google Play or Huawei account and adds the Android Premium features. Android readers who want PDF, comics, translation integration or automatic reading aloud have a clear upgrade path; those who only need the basic reader can stay on the free plan.

Platforms

FBReader supports Windows, macOS, Linux, iOS and Android. Its catalogue access and Premium additions differ by platform: OPDS is supported on Android and desktop systems, while iOS lacks third-party network catalogues and has a ten-book free limit. Android Premium is the only plan with the stated PDF, comics, translation and reading-aloud additions.

Who it's for

FBReader is a good fit for readers with varied ebook formats who want synchronized collections, bookmarks and reading positions across supported devices. It is less suitable for iOS readers who rely on OPDS catalogues or need more than ten books without paying, and for anyone seeking an open-source reader.

Pros and cons

Pros

• Supports ePub, fb2, mobi, HTML, RTF and plain text, making it useful for libraries in mixed formats.
• Book Network syncs collections, positions, bookmarks and shelves across supported devices.
• Android Premium adds PDF and comics support, translation integration and automatic reading aloud for a one-time 14.99 USD purchase.
• Readium LCP-protected ePub support covers compatible protected books.

Cons

Verdict

Choose FBReader if you want a multi-format ebook reader with cross-device library and progress sync, especially on Android or desktop. Its clearest reasons to look elsewhere are iOS's catalogue and free-library limits, Android's file-access restrictions, and the closed-source code.
