What’s AZW3?
The newer Kindle ebook format (KF8). Kindle apps and Calibre libraries use it for DRM-free books.
This AZW3 to EPUB converter turns Kindle KF8 ebooks into EPUB for Apple Books, Kobo, Google Play Books and other reading apps. Everything runs in your browser, so the book stays on your device.

Limits
