What is EPUB and Why Convert to MOBI?
EPUB is the open standard for ebooks supported by most e-readers. But Amazon Kindle uses its own MOBI/KFX format and does not natively support EPUB files.
Converting EPUB to MOBI lets you read any EPUB book on your Kindle device or the Kindle app on any device.
What is EPUB?
EPUB is the open-standard ebook format maintained by the W3C. It is supported by Kobo, Nook, Apple Books, and virtually every e-reader except Kindle.
EPUB uses reflowable text that adapts to any screen size. It is the most widely used ebook format outside of Amazon's ecosystem.
What is MOBI?
MOBI is Amazon's ebook format used by Kindle devices and apps. While being replaced by KFX, MOBI remains widely supported.
MOBI files can be sent directly to your Kindle via email (your Kindle email address) or transferred via USB cable.
