Option 1: Send to Kindle (easiest)
Amazon's Send to Kindle service accepts EPUB files and converts them for your Kindle automatically. You can use it by:
- emailing the EPUB to your Kindle's email address (found in your Amazon account under devices),
- using the Send to Kindle website in a browser, or
- using the Send to Kindle app on a computer, or the share button in the Kindle phone app.
The book appears in your library on every Kindle and Kindle app.
Option 2: Convert and copy over USB
If you prefer copying files with a cable, convert the EPUB to a Kindle format first:
- EPUB to AZW3: the modern Kindle format, with better layout support. Best for current Kindles.
- EPUB to MOBI: the older format, for very old Kindles.
Connect the Kindle to your computer and copy the file into its documents folder.
Note that Send to Kindle no longer accepts MOBI files, so use AZW3 or EPUB for new books.
Option 3: PDF
EPUB to PDF works on any device, but PDF pages do not reflow, so text can be small on a Kindle screen. Use it mainly for printing.
Why some books will not convert
Books bought from stores such as Kobo, Google Play or Apple Books are usually protected with DRM. DRM-protected books cannot be converted. DRM-free books, such as those from Project Gutenberg, Standard Ebooks and many independent authors, convert without problems.
