Amazon Announces New Kindle Format 8

Update to this post: The new KindleGen 2 and Kindle Previewer with Kindle Format 8 (KF8) support are now available for download. See

Amazon have announced a new Kindle Format 8  with HTML5 Support and will be introducing a bunch of enhancements to their Kindle Publisher Tools and Publishing Guidelines.

“KF8 is the next generation file format for Kindle books – replacing Mobi 7. As showcased on Kindle Fire, KF8 enables publishers to create great-looking books in categories that require rich formatting and design such as children’s picture books, comics & graphic novels, technical & engineering books and cookbooks.

“Kindle Format 8 replaces the Mobi format and adds over 150 new formatting capabilities, including fixed layouts, nested tables, callouts, sidebars and Scalable Vector Graphics, opening up more opportunities to create Kindle books that readers will love.”

This will be particularly useful to authors and publishers of graphic-rich content such as comic books, children’s picture books, and recipe books.

The new Kindle Fire will be the first Kindle device to support KF8, and then it will be gradually rolled out to the latest generation of Kindle e-ink devices and free Kindle reading apps.

There will be a number of enhancements planned to the Kindle Publisher Tools making it easier and faster for publishers to create high quality Kindle books using KF8.

What does this mean for self-publishing authors… will you need two versions of your Kindle books?

Amazon says, “Information on how to update your existing titles to take advantage of new capabilities in KF8 will be in the new Kindle Publishing Guidelines, available soon.

And you will not need to provide two versions of your titles. The upcoming updates to the Kindle Publishing Tools will take care of this. The new KindleGen 2 will convert your content so that it works on all Kindle devices and apps. You will be able to preview how your title will look on the range of Kindle devices and apps using the new Kindle Previewer 2.
