Amazon is eliminating users' ability to download Kindle books without WiFi, meaning you’ll want to move your library as soon as possible.

If you're an avid e-book reader or someone who has an extensive library of Kindle content, now is the time to back up your books: Amazon is killing the option to save e-books to your computer.

Starting Feb. 26, 2025 (via ZDNet) you will no longer be able to download copies of your Kindle books and use those files as a backup. After that date, you will only be able to download books via Wi-Fi or through the Amazon platforms.
