  • multi-format documents: supports fixed page formats (PDF, DjVu, CBT, CBZ) and reflowable e-book formats (EPUB, FB2, Mobi, DOC, CHM, TXT). Scanned PDF/DjVu documents can also be reflowed with the built-in K2pdfopt library.

  • full-featured reading: multi-lingual user interface with a highly customizable reader view and many typesetting options. You can set arbitrary page margins, override line spacing and choose external fonts and styles. It has multi-lingual hyphenation dictionaries bundled into the application.

  • integrated with calibre (search metadata, receive ebooks wirelessly, browse library via OPDS), Evernote (export hightlights), Wallabag, Wikipedia, Google Translate and other content providers.

  • optimized for e-ink devices: custom UI without animation, with paginated menus, adjustable text contrast, and easy zoom to fit content or page in paged media.

  • extensible: via plugins
