Have you encountered a problem with a AZW file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a AZW file here. In the further part of this page we have added a list of programs that should open your AZW file. It is enough you choose a proper application for your operating system, download and install it.


Azw files are electronic books in the so-called Amazon Kindle eBook format. This format is the native Ebook format of the Amzon Kindle and can only be read with these devices or the Amazon Kindle readers for Windows, Mac OSX and various mobile platforms such as the iPhone.

The Amazon Kindle is a reader (ebook reader) for electronic books, magazines and other publications. Commercial AZW files can only be purchased on Amazon and must be transferred to the Kindle for mobile reading.

The AZW format is in principle a version of the Mobipocket (prc) ebook format extended by some DRM functions. Under certain circumstances, unprotected AZW files can also be read with the Mobipocket Reader by simply renaming the extension AZW to prc.

To create AZW files yourself, there is Amazon KindleGen. Among other things, this command line program can be used to convert html and epub files into the AZW format. Alternatively, you can also create a Mobipocket book (prc, mobi) with the MobiPocket Creator or Reader, for example, and change the file extension to AZW. The Kindle recognizes this book as a DRM-free AZW book.

Amazon now also uses the endings azw1 and tpz for its ebook files, which both represent an extended format and are not directly compatible with AZW.

Programs which can open a AZW file

How to open a AZW file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the AZW file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a AZW file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support AZW files. At this point we are looking for disk space where the application was installed in and we can link it with a AZW file. Since then, our operating system will use the selected program to support all AZW files.

Other issues

Despite the described problem with AZW there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the AZW file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the AZW file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
