Learn About Sending Documents to Your Kindle Library

Send to Kindle is a service that allows you to send documents to your Kindle library on your Kindle devices and Kindle app at no additional cost. Upload documents through the web, an authorized email address, the Kindle app for iOS and Android devices, or a Send to Kindle application if available. All documents sent through Send to Kindle are protected with end to end encryption.

Note: Starting November 2023, we’ll be reducing support for sending MOBI files to your Kindle library via Send to Kindle for Email. Additionally, we’ll end support for sending MOBI files to your Kindle library through any Kindle apps on iOS or Android, or Send to Kindle apps on the desktop. This change won't affect any MOBI files already in your Kindle library. You can still read them with Kindle. MOBI is an older file format and won't support the newest Kindle features for document.
