What is an azw3 file?

The extension .azw3 refers to files of Amazon “Kindle Format 8” (KF8) eBook. The file structure of AZW3 is an enhanced version of the standard AZW file format which was built off the Mobipocket format and was used by Amazon earlier.

AZW3 format supports HTML5, CSS3, and several other formatting techniques, so it has better performance than AZW and MOBI. The formatting, typesetting, and layout of eBooks in AZW3 format are no worse than EPUB. Amazon pushed out AZW3 to replace MOBI and it becomes the mainstream Kindle format.

Amazon also adds its DRM scheme for digital rights protection and anti-piracy to AZW3 format. Kindle’s publishing program, KindleGen is provided by Amazon for publishers to create great-looking kindle books.
