.azw4 file extension is a file format developed by Amazon and is used by applications specifically designed for e-readers. It is mainly found on Kindle e-reader devices, a Kindle software is also available for desktops that allows interpretation and reading of azw4 files. It is used to read e-books normally purchased online. The greatest benefit that comes with using azw4 is that text does not have to stay static, so files transferred from a device with a larger screen to one with a smaller screen are adjusted and one does not have to zoom in order to read.
The American company Amazon is a recognized powerhouse when it comes to all things related to books. Their proprietary eBook readers dubbed the Kindle which was first released in 2007 is a testament to this. The .azw file format is the filename extension associated with eBooks designed to be read on Amazon's proprietary Kindle device and through their free but closed source Kindle software for smartphones, PCs, and Macs. The format is incompatible with any device other than kindle and its associated software. In order to open files saved in this format on non-kindle devices, one would have to convert the file to another format such as the open ePub format or PDF. Some converters can also convert other formats into .azw files which can later be opened on a kindle device or application.
