Usage statistics

We count page views and operations. A random cookie identifies a browser profile; after sign-in its activity is linked to your account. Your last IP and its observation date are visible only to the site owner and kept for up to 90 days. Daily counts are kept for 90 days, and inactive profiles are removed after 90 days. Formats, outcomes, error codes, and size and time ranges are counted separately. File names, contents and metadata stay on your device. Turning this off deletes the current browser profile.

Frequently asked questions

Why convert EPUB to FB2?

Many readers and apps popular in Eastern Europe — PocketBook, ONYX, FBReader — work best with FB2, which has handy footnotes and contents.

What is kept?

Title, authors, language, cover, chapters with headings, paragraphs with bold and italic, quotes, lists, tables and JPEG and PNG illustrations.

What happens to images?

The cover and illustrations in JPEG and PNG come through. Images in other formats are poorly supported by readers, so they are skipped and the file's row shows a warning.

Do purchased books work?

Books with copy protection (DRM) can't be read. DRM-free books — from libraries, your own and most free ones — convert as usual.

Why is the genre “unrecognised”?

EPUB has no FB2 genres, so the book gets “unrecognised”, as other converters do. You can fix the genre in your library manager.

Is it safe?

Yes. Only the converter itself is loaded from the site; your book is processed in your browser and never sent to a server.
