Re: Amazon support for EPUB3 ???

Hi Ruth,

As Ken mentioned, Amazon only handles conversion of fluid files. To submit
a fixed layout file, you can convert the ePub using Kindle Previewer. This
software allows you to test what works or doesn’t work on Amazon.

Here at Booknando, we produce a Fixed Layout ePub designed for Amazon, with
right and left pagination as needed, and then convert it to mobi using
Kindle Previewer and deliver this mobi file to the client.

Abraço
