Question: is azw3 compatible with kindle?
Answer: You can't send any AZW3 file to Kindle via email, but you don't need to convert it to Mobi format. Just connect Kindle to your computer, and directly copy the AZW3 file to Kindle. ... AZW3 is the official file format of Amazon ebooks now. Every ebook you purchased from Kindle bookstore will be used AZW3 format.
