Why convert FB2 to EPUB?
FB2 is a Russian XML ebook format that most mainstream readers won't open, which is exactly why converting it to EPUB matters. EPUB is the open industry standard that Apple Books, Kobo, Nook, Google Play Books, Calibre, and newer Kindles all read natively. This free tool sends your .fb2 over an encrypted HTTPS connection to our conversion server, rebuilds it as a reflowable EPUB with chapters, paragraphs, embedded images, and metadata intact, then deletes the file right after. No sign-up, no watermark.
- You downloaded a book as an .fb2 file and your Kobo, Nook, or Apple Books app refuses to open it — converting to EPUB makes it load and reflow correctly on your e-reader.
- You want to sideload a book onto a newer Kindle (which has accepted EPUB since 2022) or send it via Send-to-Kindle, neither of which accepts FB2 directly.
- You're tidying a mixed ebook library in Calibre, Apple Books, or Google Play Books and want everything in one consistent EPUB format with working chapter navigation and cover images.
FB2 vs EPUB

FB2 to EPUB — frequently asked questions
Will the chapters, cover, and images survive the conversion?
Yes. FB2 and EPUB are both XML-based, so the structure maps over cleanly. The EPUB keeps your chapter breaks and table of contents, embedded illustrations, the cover image, and metadata like title and author, while staying fully reflowable so text resizes to any screen.
Is it really free, and what happens to my file?
It's completely free with no account, no email, and no watermark. Your .fb2 is uploaded over a secure HTTPS connection to our conversion server, converted there, and automatically deleted shortly after — it is not stored or shared. This is a real server-side conversion, not an in-browser one.
Does it handle .fb2.zip files and large books?
Plain .fb2 files convert directly. If yours is a compressed .fb2.zip, unzip it first so you upload the raw .fb2. Long novels with many embedded images are fine — the converter processes the full book and returns a single ready-to-read EPUB.
How do I convert FB2 to EPUB?
Drop your FB2 file (or several) into the converter, confirm EPUB is selected as the output, click convert, then download the EPUB file. The whole thing takes a few seconds.
Is this FB2 to EPUB converter free?
Yes — it's completely free with no watermark and no sign-up required.
Is it safe to convert FB2 to EPUB here?
Yes. Your FB2 file is sent over an encrypted HTTPS connection to our conversion server, converted, and deleted automatically moments later — it is never stored, logged or shared.
Can I convert multiple FB2 files at once?
Convert one FB2 file at a time — finish one, then drop in the next.
Does it work on mobile?
Yes — the converter runs in any modern browser on phones, tablets and desktops.
