Why Convert FB2 to EPUB?
FB2 (FictionBook 2) is a popular Russian-origin ebook format widely used across Eastern Europe and available on major ebook sites. The problem is that Apple Books, Kindle, Kobo and most Western e-readers do not support it natively. Converting to EPUB opens your library to any modern device.
Most online converters upload your file to a remote server and return a download link. That is fine for public-domain books, but it is not ideal for unfinished manuscripts, recently purchased ebooks or anything personal. Because Handytool's converter runs entirely inside your browser using standard JavaScript, your book never leaves your device.

- 03

Click the download button to save the EPUB to your device. Transfer it to your e-reader via USB, Calibre or email.
What the Converter Preserves
The output EPUB is a faithful representation of the original FictionBook:
- 01All chapters and sections with a working table of contents
- 02Cover image displayed as the first page of the book
- 03Embedded illustrations and binary image elements
- 04Author name, book title and language metadata
- 05Original character encoding (UTF-8, Windows-1251 and others)
- 06EPUB 2 format with NCX navigation — supported by all major e-readers
Privacy: Your Book Stays on Your Device
The entire conversion is handled by JavaScript running inside your browser tab. Files are read directly from your local filesystem and the EPUB is built in memory, then offered as a download. No data is transmitted to any server at any point.
This also means the converter keeps working if you go offline after loading the page — useful if you are on a plane or a slow connection with a stack of ebooks to convert.
FB2 to EPUB Converter FAQ
How do I convert an FB2 file to EPUB?
Drop your .fb2 or .fb2.zip file into the upload area and click Convert. The tool parses the FictionBook XML, extracts the cover and images, and packs everything into a standard EPUB you can download in one click.
Will my book stay private?
Yes. The conversion runs entirely in your browser using JavaScript. The file is never uploaded to a server — it is read from your device and the EPUB is built locally.
Does it support .fb2.zip archives?
Yes. The converter automatically unpacks .fb2.zip files and reads the FB2 inside. Drop the archive directly without extracting it first.
Does the EPUB work on Kindle?
Yes. Send the EPUB to your @kindle.com address or use the Send to Kindle app and Amazon will deliver it to your library. Modern Kindles support EPUB natively.
Are cover art and illustrations preserved?
Yes. Embedded binary elements in the FB2 — cover and illustrations — are extracted, attached to the EPUB manifest and referenced from the chapters so they render in any EPUB reader.
Which EPUB version does it produce?
The output is EPUB 2 with an NCX table of contents — the most broadly compatible format, supported by Apple Books, Kobo, PocketBook, Calibre and Google Play Books.
