About FB2 to EPUB
Apple Books, Google Play Books and Kobo don't read FictionBook. Convert your .fb2 or .fbz book to EPUB in a few seconds – chapters, table of contents, cover and illustrations are kept, and the EPUB can be sent to Kindle too.
Frequently asked questions
What is an FB2 file?
FB2 (FictionBook 2) is an XML e-book format that is the most common e-book format in Russia, Ukraine, Belarus, Kazakhstan and Uzbekistan – most Russian-language online libraries offer books as .fb2 or zipped .fbz/.fb2.zip. Kindle, Apple Books and Word can't open it.
Can I read the EPUB on a Kindle?
Yes. Kindle now accepts EPUB through Send to Kindle, which converts it for you.
My FB2 book is in Windows-1251. Does that work?
Yes. Old FB2 files in Windows-1251 or KOI8-R are detected automatically, so Cyrillic text comes out correctly. Cover pictures and illustrations stored inside the book are kept.
Is my document kept?
No. Files travel over an encrypted HTTPS connection, are converted automatically and are permanently deleted after 1 hour. Nobody looks at them and they are never used for AI training.
Is FB2 to EPUB free?
Yes – completely free, with no account, no daily limit and no watermark.
Are my files safe?
Files are sent over an encrypted HTTPS connection, processed automatically by our servers, never shared and permanently deleted after 1 hour. Nobody looks at your documents.
Do I need to install software or sign up?
No. It works in any browser on Windows, Mac, iPhone and Android. No account needed.
Is there a watermark?
Never. Your converted files are clean, with no watermark or branding.
