Open a book file and read — no conversion, no desktop app, no sending anything anywhere. Full EPUB and FB2 support, including the footnotes, poems and letters FB2 books are full of.



01
Double-click an EPUB or FB2, or drop it on a tab. Books stay on your machine — there is no cloud library to sign into.
02
Inline footnotes, verse formatting, nested sections and embedded images — the details most readers flatten or drop.
03
Progress, bookmarks and your typography settings persist per book, locally.
04
Adjustable measure, two-page spread on wide screens, and a night mode that doesn’t just invert the images.
No — no legitimate reader can open books locked by the store that sold them. DRM-free EPUB and FB2 open directly.
Conversion is a separate tool: the EPUB ↔ MOBI converter runs on this site with nothing to install, or as its own extension.
It’s the dominant format for Russian-language e-books, and most readers treat it as an afterthought — flattening footnotes, verse and nested sections. We don’t.
