Why Convert MOBI to EPUB?

Amazon officially retired the MOBI format: since 2022, Send to Kindle no longer accepts .mobi files, and the Kindle ecosystem has moved to EPUB-based ingestion. Outside Amazon, virtually every reader — Apple Books, Kobo, Google Play Books, BOOX, PocketBook — standardized on EPUB. If you still have a library of MOBI files, converting them is the only way to keep them readable on modern devices and apps.

Escape the Kindle lock-in

MOBI only ever worked inside Amazon’s ecosystem. EPUB opens everywhere — switch readers and devices freely without losing your library.

Rescue aging collections

Old free ebooks, Smashwords downloads, and early Kindle-era files are often MOBI-only. Convert once and future-proof the whole archive.

Better typography and features

EPUB 3 supports modern CSS, accessibility metadata, embedded fonts, and popup footnotes — capabilities MOBI never had.

Frequently Asked Questions

Which Kindle formats can I convert?

The converter accepts .mobi, .azw, and .azw3 files. AZW3 (KF8) files contain richer formatting and generally produce the cleanest EPUB output.

Will the converted EPUB work on a Kindle?

Yes — modern Kindles accept EPUB through Send to Kindle, which converts it to Amazon’s internal format automatically. Ironically, EPUB is now the officially supported way to get books onto a Kindle.

Can I convert DRM-protected Kindle books?

No. Books purchased from the Kindle Store are typically DRM-locked and cannot be read by third-party converters. DRM-free MOBI/AZW3 files — including many free and public-domain books — convert without restriction.

Is my ebook stored on your servers?

No. Files are processed in a temporary directory that is wiped as soon as the converted file is delivered. Nothing is retained, indexed, or used for training.
