How to Remove Kindle DRM with Epubor Ultimate
Are you looking forward to using Epubor Ultimate to remove DRM from Kindle books? Follow the detailed steps below to decrypt your digital book collection in a few clicks.
Step 1: Register for the Kindle App
Run the Kindle for Windows (PC) or Mac computers. Then, log in with the active credentials of your Amazon account.
Within a few minutes, your Kindle library will display. It will show all the books you have purchased from the Amazon Kindle store in your account.
Step 2: Download Kindle Books to your PC
Go to the "Kindle library" and right-click the cover of the book you wish to download. Select Download.
💡Note: Ensure that you download the books to your local computer. This way, you can successfully remove the Kindle DRM. Once saved, you can find the books in your Downloaded tab.

Hands-on Epubor Ultimate Review: Putting Epubor to the Test
While format conversion is a standard feature in most eBook tools, the ability to remove DRM is the most critical factor for evaluation and review. To see how Epubor Ultimate stands up, I conducted a stress test on a Windows 11 environment using Epubor Ultimate v3.0.16 and Kindle for PC v2.8.0. Given that Amazon's latest encryption is arguably the toughest to crack, I selected five Kindle titles (a mix of KFX and AZW3 formats) for a "limit testing" session.
My hands-on test confirmed that Epubor Ultimate can still successfully strip Kindle DRM. The exported EPUB files remained stable, with no noticeable formatting glitches when viewed on Calibre or mobile devices.
However, the experience was not without its friction. First, the user interface feels dated; while it requires fewer clicks, the lack of modern, intuitive guidance means users may face a slight learning curve during initial setup. More critically, I hit a performance bottleneck with the newer KFX encryption. While average books took about 3 minutes to convert, two of the "hardened" KFX titles lagged significantly, taking around 10 minutes to process. For users looking to sync a large library, this lack of efficiency could be a dealbreaker.
If you find Epubor's performance or interface lacking, there is a more efficient Epubor alternative for 2026.
