How to convert AZW3 to EPUB
- Add your .AZW3 file - drop it in the box above or click to browse.
- Convert it to .EPUB in a few seconds.
- Download your new .EPUB file.
What to expect
- Books bought from the Kindle Store are DRM-protected - Calibre will import them but refuse to convert, showing a DRM error.
- Text, chapter structure, and images carry over cleanly; fixed-layout designs such as children's books or magazine-style non-fiction may reflow differently in EPUB.
- Newer Kindle purchases often use the KFX format, which is distinct from AZW3 - check your file extension, as
.kfxfiles require a different workflow.
Frequently asked questions
Can I convert a Kindle book I bought on Amazon?
No - purchased Kindle books have DRM that prevents conversion. Only DRM-free AZW3 files (self-created content, public-domain books, or DRM-free store purchases) can be converted.
Why does Calibre show a DRM error when I try to convert?
The error means the file is copy-protected. Calibre cannot convert DRM-locked files, and circumventing DRM may violate Amazon's terms of service or local law.
Will the EPUB look the same as the original Kindle book?
For most reflowable books - novels, essays, general non-fiction - text and chapter structure are preserved faithfully. Complex fixed layouts may render differently depending on the EPUB reader.
Is AZW3 the same as KFX?
No - KFX is a newer Kindle format used for most recent Amazon purchases. If your file extension is
.kfx, a different converter or plugin is needed.Programs that convert AZW3: Calibre · Hamster Free eBook Converter · Calibre for Mac · Calibre for Linux
