What is a .AZW file?

AZW is Amazon’s original Kindle e-book format, based on MOBI. Opened by Amazon Kindle.

Did you know
  • AZW arrived with the very first Amazon Kindle in 2007.
  • AZW is a proprietary variant of the Mobipocket e-book format, which Amazon gained by buying the French firm Mobipocket in 2005.
  • It wrapped that format in a new DRM scheme that tied a purchased book to a particular device.
