People are still in a dilemma when it comes to the best digital book format for Kindle. At this point, the two formats that are considered are ePub and MOBI.
Now, what is the format that Kindle actually uses? Many may claim it to be AZW or AZW3. AZW is in fact the encrypted final format dispensed to the kindle from Amazon store when a book is purchased. You can’t create this one for yourself and also in case if you succeed in doing so, this can’t be uploaded to a KDP. AZW3 on the other hand emulates KF8 using a free software named Calibre. Again, this can’t uploaded to KDP.
Is ePub readable on Kindle?
When an ePub is uploaded to KDP, a MOBI files gets created; KDP accepts ePub. However, creating the said version is not that easy. Most of the companies offering Kindle Conversion Services after getting approval from clients for ePub makes some modifications and use this revised content for creating the final compatible Mobi file. Conversion at KDF has many pitfalls.

Also there is a complete “KF7” MOBI file which is tweaked optimally to be accessed and read on the earlier devices. In addition to the said, there is an improved “KF8” MOBI file. Thus every reader can read the delivered book in a perfect manner on their specific reading devices.
