Guides

Convert an EPUB ebook into a Kindle AZW3 (KF8) file. The conversion runs in your browser, so the book is never uploaded.

How to use it

  1. Drop an .epub file onto the upload box.
  2. Press Convert to AZW3.
  3. Download book.azw3.

What is carried over

  • The book's title, author, publisher, description and language.
  • All chapters in reading order, with the book's stylesheet.
  • The table of contents (from the EPUB's own navigation) and links between chapters.
  • JPEG, PNG and GIF images and the cover.

Limits

  • DRM-protected books can't be read. Only DRM-free files convert.
  • WebP and SVG images, embedded fonts and nested table-of-contents levels are left out; the contents list is flattened to one level.
  • All of the book's stylesheets are merged and applied to every chapter.
  • Newer Kindle devices and apps accept EPUB through Send to Kindle; AZW3 is mainly useful for older Kindles and for copying a book over USB.

Frequently asked questions

Is my book uploaded anywhere? No. Everything happens on your device.

AZW3 or MOBI? AZW3 (KF8) keeps styling, working links and a table of contents. Pick MOBI only for very old readers.
