Amazon Kindle Will Support EPUB Books, Abandoning MOBI Format

Kindle Paperwhite

This morning, I received an email from Amazon saying that the Kindle will no longer support MOBI books because, after 15 years of refusing to do so, they are embracing the EPUB book format. Read on for the full email from Amazon with all the details, including when this change goes into effect.

Dear Kindle Customer,

Thank you for using the Send to Kindle service to send personal documents to your Kindle library. We wanted to let you know that starting August 2022, you’ll no longer be able to send MOBI (.mobi, .azw) files to your library. Any MOBI files already in your Kindle library will not be affected by this change.

MOBI is an older file format and won’t support the newest Kindle features for documents. Any existing MOBI files you want to read with our most up-to-date features for documents will need to be re-sent in a compatible file format.

Also, compatible formats now include EPUB (.epub), which you can send to your library using your Send to Kindle email address. We’ll also be adding EPUB support to the free Kindle app for iOS and Android devices and the Send to Kindle desktop app for PC and Mac.

If you have any questions, please visit our help page or contact our Customer Service team.

Regards,
The Kindle Team

  1. Thank you. But what other Kindle format should now be used, if not Mobi? (And other than Epub)
