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
- Drop an .epub file onto the upload box.
- Press Convert to AZW3.
- 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.
