Which ebook format should you choose?

EPUB is the open standard read by Apple Books, Kobo, Google Play Books and most e-reader apps, and Kindle now accepts it through Send to Kindle. MOBI is the older Kindle format and AZW3 the newer one; both open mainly in Kindle devices and apps. PDF keeps fixed pages, which suits computers and printing but is harder to read on small screens.

DRM-free files only

Books bought from the Kindle, Apple or Kobo stores are usually protected with DRM and cannot be converted. The converter works with DRM-free ebooks, such as your own files, free public-domain books and books sold without DRM.

Frequently asked questions

EPUB, MOBI and AZW3 are reflowable, so text adapts to the screen. Converting to PDF fixes it onto pages; converting a PDF to an ebook works best with text-based PDFs.
