Now you're working on Milestone 2.
I'm not always sure what question I'm being asked. Really, there are only two eBook formats that are still remaining in the USA, and, when you look around, in the world.
If you've Googled, you've likely seen all sorts of claims, ranging from some folks telling you that you can put an ePUB on Kindle, to the idea that using Word is the best "Kindle eBook format. The former is the actual, final, encrypted Kindle format that is dispensed from the Amazon store, to your Kindle as a purchased book.
That's not a format that you can make yourself. The latter, AZW3, is a file format, created to emulate what's called "KF8," the more-advanced Kindle formatting by a piece of free library software called Calibre.
Obviously, that format, then, lacks utility. Fine for personal use, but useless for publishing.
If someone starts yammering away at you, talking about how you can convert your file to AZW or AZW3 format, for the purposes of publishing--that's not someone to whom you should be listening. If you've banged around some more, you've seen some folks, including people like me, who will tell you that you can use an ePUB to Kindle formatting process.
This is absolutely true. So, you can, then, effectively ePUB Kindle. Even here at Booknook. Amazon does this because they continue to support even the oldest of their e-reading devices.
It's the KF8 MOBI files that will have embedded fonts, can float images next to paragraphs of text, display Dropcaps and that sort of thing. It's great for you as both a reader, or an author.
When a reader buys your book, they receive the copy of the book--either KF7 or KF8 format--that suits their device. Lastly, you should know what file formats you can, and cannot, upload at the KDP in an effort to build your book, or put your book on sale.
If you're doing it yourself, the KDP will take files uploaded in. We highly recommend that you don't try uploading a PDF--the results are almost always very, very poor. If you're tecchy, you can try to create your own ePUB and upload that, because.
Your best option is to upload a complete, fully-crafted and custom-built MOBI file, created for your own book.
This method results in the fewest "suprises" at the KDP. And that's the best eBook Format for Kindle--the one that doesn't give you any unpleansant surprises.The Kindle has become wildly popular with e-book readers, and users often seek to expand the Kindle experience.
One interesting but little known function that Kindle provides is the ability to copy and automatically convert pages of books to Portable Document Format (PDF) files. The former is the actual, final, encrypted Kindle format that is dispensed from the Amazon store, to your Kindle as a purchased book.
That's not a format that you can make yourself. And, even if you could, you can't upload that format at the KDP, the Kindle Digital Publishing platform.
