This article describes what AZW files are, how to open them on your computer or other device, and how to convert the eBook to another format, such as PDF or EPUB, so you can read it on a specific device.
What is an AZW file and how do I open it?
A file with the AZW file extension is a Kindle eBook Format file. It is based on the Mobipocket (MOBI) format and is usually DRM protected to prevent copying.
These files are used by Amazon's Kindle eBook readers, so you'll likely encounter them when you download eBooks from the Internet or transfer Kindle books to your computer.
In these files you can store things like bookmarks, notes, last reading position, page numbers that correspond to the physical version of the book, and more.
