There are a few reasons why some Kindle users might miss this feature. It’s useful if you don’t have access to a Wi-Fi network, and although it’s a tedious process since purchased books can only be downloaded one at a time, there’s some peace of mind in knowing you have offline copies of all your books.
The feature is also the easiest way to convert books purchased from Amazon to other formats like EPUB that can be used on alternative devices such as a Kobo. Books downloaded through Amazon’s website are delivered in the older AZW3 format which allows DRM to be easily removed using various software tools.
Older Kindle models also store books in the AZW3 format, and they can be extracted by connecting the device to a computer with a USB cable. But modern Kindles use the newer KFX format (first rolled out in 2015) which introduced improved font rendering, better layout capabilities, and DRM that’s nearly impossible to circumvent.
But the pop-up that appears when selecting the download option now includes an additional warning. “Starting February 26, 2025, the ‘Download & Transfer via USB’ option will no longer be available. You can still send Kindle books to your Wi-Fi enabled devices by selecting the ‘Deliver or Remove from Device’ option.“
Amazon confirmed the removal of the book download feature in a statement to The Verge. “Customers can continue reading books previously downloaded on their Kindle device, and access new content through the Kindle app, Kindle for web, as well as directly through Kindle devices with WiFi capability,” said Amazon spokesperson Jackie Burke.
