Convert FB2 to EPUB.
Turn a FictionBook (FB2) ebook into EPUB, the format read by Apple Books, Kobo, Google Play Books and Send to Kindle.
From a regional format to a universal one
FB2 is widely used in Russian-language and Eastern European libraries, but most ereaders outside that market do not read it. EPUB is understood almost everywhere.
Structure is preserved
FB2 is structured XML with sections, titles, epigraphs and poems. Calibre maps those onto EPUB chapters and styles, so the book keeps its shape.
Size change
The EPUB is compressed, so it is usually smaller than an uncompressed FB2.

This re-flows the book into EPUB, carrying chapters, the table of contents and images. Reflowable ebook formats adapt to the reader's screen and font size. Heavy fixed layouts (comics, textbooks) convert less cleanly.
Common questions
Is it free?+
Yes. Convert FB2 to EPUB free. No signup and no watermark. Free covers 10 server conversions a day, up to 100 MB a file. Pro removes the daily limit and raises the file limit to 2 GB.
Is my file private?+
Your file is uploaded to a private bucket, converted on our own engine, and auto-deleted after 1 hour. It is never sent to a third-party converter.
Can I send the result to a Kindle?+
Yes. Send to Kindle accepts EPUB, so this is the simplest route from an FB2 book to a Kindle.
Are covers and metadata kept?+
Calibre carries the title, author, annotation and cover that the FB2 file declares into the EPUB.
