Amazon does not make it easy for developers to create Kindle books in their apps, but they provide tools to convert EPUB books to Kindle. Perform the following steps to convert an EPUB book to Kindle
- Download Amazon’s Kindle Previewer app.
- Launch Kindle Previewer.
- Open your EPUB book by choosing File > Open Book.
- Choose File > Export to export the book.
There are two Kindle formats that Amazon’s Kindle Previewer can export: KPF and MOBI. Older Kindle devices support MOBI but not KPF. Choosing MOBI will ensure every Kindle can read your book. I did some Internet searching and couldn’t find any information on what advantages KPF provides over MOBI.
