AZW3 called Amazon Kindle Format 8 (KF8) is a relatively new format and well supported by Kindle Paperwhite. But sometimes Kindle 5 and some third-party reading apps are unable to identify the azw3 format perfectly. Apparently Amazon also doesn’t accept azw3 files delivered via e-mail, there’re only two ways to push it to your Kindle, one is converting azw3 to mobi, the other, is via USB cable. Just because the mobi format is already widely supported, it’s very necessary to convert a azw3 file to a mobi file for reading convenient on old Kindles.
