Vellum: Upload Your Kindle EPUB and Convert to MOBI

Due to limitations with Amazon’s KindleGen, Vellum will no longer export .mobi files.

Instead, Vellum will export a special file called a “Kindle EPUB” that is designed to be uploaded to Amazon or compiled into a .mobi file. You can upload this Kindle EPUB to BookFunnel and we will automatically convert it to a .mobi for distribution.

When uploading your book files, you must upload both of these Vellum-generated files:

  1. Generic EPUB
  2. Kindle EPUB

Why are both EPUB files necessary?

The Kindle EPUB has a lot of Amazon-friendly formatting to make sure the book looks perfect when uploaded to Amazon. It is not a file that should be sent directly to readers.

A Kindle EPUB is intended to be uploaded to Amazon, or it can be uploaded to BookFunnel and converted to .mobi for distribution.

Please upload the Kindle EPUB for Kindle apps and the Generic EPUB for everything else.
