If you often purchase ebooks from Amazon Kindle, you must have come across AZW format if you ever tried to download them. AZW is the most popular format adopted. Although Amazon has recently employed a new KFX DRM, the books are still saved as AZW format when you download them from Kindle for PC/Mac. All the Kindle AZW books are DRM-protected and only supported by Kindle devices and Kindle apps. To read Kindle AZW books freely on other devices, you need a AZW Converter to help you.
