Guides

Convert a Kindle AZW3 (KF8) ebook into a standard EPUB file that opens in Apple Books, Kobo, Calibre, Google Play Books and most other readers. The conversion runs in your browser, so the book is never uploaded.

How to use it

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

What is carried over

  • The book's title, author, publisher, description and language.
  • All chapters in reading order, with a generated table of contents.
  • Images, embedded stylesheets and the cover.

Limits

  • DRM-protected books (most purchases from the Kindle store) can't be read and are rejected. Only DRM-free files convert.
  • Kindle-specific internal links are dropped, since they have no meaning outside the original file, so footnote jumps may not work in the EPUB.
  • Fixed-layout books (comics, children's picture books) are not reproduced faithfully.

Frequently asked questions

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

Does it also read MOBI? Yes — older .mobi files open too.

Why does the EPUB look plainer than the original? The converter keeps the book's own styles, but device-specific Kindle layout rules have no EPUB equivalent.
