About the AZW3 format

AZW3 replaced the older MOBI and AZW formats on Kindle devices from 2011. It supports richer layout, fonts and images.

Other readers do not open AZW3. Calibre and this converter turn DRM-free AZW3 files into EPUB or PDF, and EPUB, DOCX or PDF into AZW3 for sideloading onto a Kindle.
