Email to Kindle

You can easily send documents to your Kindle using email, which can also be used to convert EPUB files to a Kindle-compatible format.

Detailed Introduction: Amazon provides a unique email address for each Kindle device, which can be used to send documents directly to your e-reader. When you send an EPUB file to this address, you can include the word “convert” in the subject line, and Amazon’s servers will automatically convert it to a format your Kindle can read.

Detailed Steps:

  1. Locate your Kindle’s email address by going to your Amazon Account’s Manage Your Content and Devices page, then to the “Devices” tab.

  4. Put “convert” in the subject line to ensure Amazon’s system converts your file.
  5. Attach the EPUB file to the email and send it.

Summary: This method is incredibly convenient because it doesn’t require any additional software and can be done from almost any device with email capability. The downside is that you must have a Wi-Fi connection for your Kindle to download the converted file, and the file size is limited by Amazon’s email service.
