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.
What Analyser reads
Identify e-book files: Kindle (MOBI, AZW, AZW3) and DjVu. FictionBook (FB2) now opens in a full reader (see Text & markup above).
Depth of analysis
.AZW is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
Open a .AZW file
Drag a .AZW file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
