What to expect
- DRM is the only real blocker - Kindle Store purchases are account-locked and trigger a DRM error in Calibre; only DRM-free
.azwfiles can be converted. - AZW shares its internal container format with MOBI, so text, chapter structure, cover art, and embedded images all transfer cleanly; a few Amazon-specific metadata fields such as the ASIN are dropped, which does not affect reading.
.mobiis a legacy format abandoned by Amazon in 2022; if your target device or app supports.epub, that is the better output choice.
Frequently asked questions
Can I convert a Kindle Store purchase from AZW to MOBI?
No. Amazon DRM locks the file to your account and Calibre will report a DRM error. Removing that protection violates Amazon's terms of service.
How can I tell if my AZW file has DRM?
Add it to Calibre - if it imports and converts without errors it is DRM-free. A DRM error on import or conversion confirms the file is protected.
What is preserved in the converted MOBI file?
Text, chapters, cover art, and inline images carry over correctly. A handful of Amazon internal metadata fields are dropped, but these do not affect reading.
Should I convert to MOBI or EPUB?
EPUB is the better choice for most uses - Amazon has accepted
.epub via Send to Kindle since 2022 and every non-Kindle reader supports it. Choose .mobi only for older Mobipocket apps or devices.
