Now, we will have to first download two plugins – DeDRM and KFX. The DeDRM can be downloaded from the following link, while the KFX plugin can be installed from the Calibre app itself (refer to step 4).

Step 5: Load Kindle books and remove DRM protections

• Now that all the plugins are installed, simply drag and drop the downloaded AZW3 files (under Documents > My Kindle Content) to your Calibre library.
• Calibre will automatically remove the DRM for these books. To be sure, click on Convert books at the top.
• Select an output format at the top right corner.
• And click OK.
  • If your books are converted without any error messages, then you have safely removed the DRM from them. You can now save them wherever you like. To do so, right-click on a file and Save to disk.
• And select a folder.
• All your converted and DRM-free files will be in this folder.

It is ideal to get the latest version of Calibre to DeDRM books. But Calibre alone won’t be able to do so. You will need the DeDRM and KFX plugins as well to fully DeDRM your Kindle books.

Use a Kindle Paperwhite (v5), then open Amazon, manage digital purchases, and download and transfer book files. Save them to the PC, then drag and drop into Calibre.
