About MOBI to EPUB

MOBI to EPUB helps when a book you own as a MOBI file needs to move off the Kindle ecosystem: onto a Kobo or Tolino, into Apple Books or Google Play Books, or into a reading app on Android. EPUB is the format almost every non-Kindle reader supports. Upload the .mobi and download an .epub. Books in the newer AZW3 format go through AZW3 to EPUB.

It works with DRM-free MOBI files, like those from authors and publishers who sell without copy protection, public-domain collections and your own conversions. Books bought in the Kindle Store usually carry DRM; those can't be converted, and we don't remove DRM.

FAQ

MOBI to EPUB: questions and answers

Can I convert Kindle Store books with MOBI to EPUB?
Only if they're DRM-free. Most Kindle Store purchases are copy-protected, and those can't be converted here; we don't remove DRM.
Why convert MOBI to EPUB?
Because many e-readers and reading apps outside Amazon, such as Tolino, Apple Books and Google Play Books, read EPUB but not MOBI, and a Kobo gives EPUB books its full set of reading features. If a book has to go the other way, onto an older Kindle, EPUB to MOBI handles it.
How do I add the EPUB to Apple Books?
On an iPhone or iPad, open the downloaded file and choose Books; on a Mac, drag it into the Books app.
Is MOBI to EPUB free, and how big can a book be?
Yes. You have 2 tasks without an account and 2 a day with a free one, for books up to 50 MB, and VIP has no task limit.
Is my book safe on your server?
Yes. It travels over HTTPS, is converted in an isolated process and is deleted automatically after one hour.
