What to expect

  • Conversion only works on DRM-free .azw files - Kindle Store purchases are account-locked and any tool will refuse to process them.
  • Body text is preserved faithfully; custom fonts may not carry over, since AZW/MOBI has limited font-embedding support, so the .azw3 output may fall back to device defaults.
  • AZW3 (KF8) requires a Kindle Touch (2011) or newer - first- and second-generation Kindles do not support it.

Frequently asked questions

Why does Calibre show an error when I try to convert my AZW file?
Almost always DRM. Books purchased from the Kindle Store are account-locked; check the Calibre jobs log for the exact message. DRM-free AZW files convert without issues.
Will the converted AZW3 look different from the original?
Body text and images are preserved. Fonts or fixed-layout elements that AZW/MOBI could not embed may fall back to device defaults in the .azw3 output.
Should I convert to AZW3 or EPUB?
Choose AZW3 if you plan to sideload the file to a Kindle over USB. Choose EPUB if you want a format that works on virtually every non-Kindle reader.
Does the converted AZW3 work on all Kindle models?
AZW3 is supported on Kindles from the 2011 Kindle Touch onward. Very early Kindles (2007-2009) do not support it - keep the original .azw for those devices.
