Convert Kindle e-books to EPUB, the format almost every other e-reader and reading app uses. The book's chapters become EPUB chapters, its pictures and embedded fonts are carried across, its table of contents becomes the EPUB's contents (for both new and older readers), and its title, author, language, publisher and cover go into the EPUB's details. Links from one part of the book to another are kept, to the exact spot wherever the Kindle file records it. It is free to use, with no account and no upload limit, and it runs entirely in your browser: nothing is uploaded, and while the page stays open, a feature you have already used keeps working offline.
Only books without DRM can be converted: books you made yourself, got from a publisher or a site such as Project Gutenberg, or saved without copy protection. Books bought from the Kindle store are locked to Amazon's apps, and this page says so rather than trying to unlock them. The newer KFX format is not read here either. To read a Kindle book without converting it, open it in the MOBI & AZW3 Reader; to print it, EPUB to PDF turns .mobi and .azw3 books straight into PDFs.
- Can I convert Kindle books I bought from Amazon?
- Not if they have DRM, which store-bought Kindle books almost always do. DRM locks the text so only Amazon's apps and devices can read it, and this page does not remove it. A locked book is recognised and refused with a plain message. Books without DRM, such as ones from Project Gutenberg, from publishers who sell DRM-free, or ones you made yourself, convert fine.
- What is the difference between MOBI, AZW3 and EPUB?
- MOBI is the old Kindle format, AZW3 (also called KF8) the newer one with better styling, and both are read only by Kindle devices and apps. EPUB is the open standard used by Apple Books, Kobo, Google Play Books, Nook, Thorium, Calibre and most other readers. Converting to EPUB lets you read the book anywhere else.
- Does it work with KFX files?
- No. KFX is the format the Kindle app downloads today; it is a different design altogether and is nearly always locked with DRM. The page tells you when a file is KFX. Only .mobi, .azw3 and older .azw books without DRM are converted.
- Will the EPUB look the same as the Kindle book?
- Very nearly. Text, headings, italics, bold, lists, tables, pictures and the book's own stylesheets are carried across, and so are embedded fonts. Scripts, forms and anything that could run code are left out, and some Kindle-only layout tricks become plain text. Each reading app then shows the book in its own way, as it does any EPUB.
- Is the EPUB valid?
- It is written as EPUB 3 with the parts the standard requires: a package file, a navigation document, an NCX contents for older readers, and well-formed XHTML chapters. Books made this way were checked with EPUBCheck, the official validator, while this page was built.
- Are my books uploaded?
- No. The Kindle file is read and the EPUB written by code running in this browser tab, so your books stay on your computer. There is no account, no daily limit and no file size fee.
