How to Remove DRM from Kindle & eBooks with Calibre

Eliminate DRM from your eBooks

DRM can prevent you from transferring books to all of your personal reading devices. Calibre and a little elbow grease can help you get around it.

Even if you purchase eBooks from Amazon for your Kindle device, some of them might contain DRM which prevents you from copying them to read on other devices. There are several reasons why DRM is a bad thing for consumers, but there might be laws in your region that protect its placement. Before continuing with removing it, be sure to check your local regulations. And, I don’t recommend sharing books with others that you’ve removed DRM from. This guide is designed for personal use and backup, in which case you shouldn’t run into any problems.

Note: This does not work for pulling protected books directly from a Kindle Fire Android tablet. This will however work on E-inks and some other non-Kindle tablets.

Required Downloads for PC

The first thing you need to do is download and install Calibre and Kindle for PC. Then setup and download your books onto Kindle for PC.

Once you have those two programs installed, you need to configure Alf’s DRM tools for Calibre. Unzip the folder that was downloaded from Alf’s, and then put the Calibre_Plugins folder somewhere you’ll be able to easily find it.

Now open up Calibre preferences. This can be done by clicking the right arrows and then selecting the gear icon that says Preferences.

In the Preferences window click Plugins.


Select to “Load plugin from file.”

Now browse to the Calibre_Plugins folder extracted from Alfy’s pack. Open the first zip file on the list, and then repeat the process again for all five of the plugin zip files.

add plugins

After you’ve added all of the plugins they’ll be listed in the “File type” plugins list of Calibre. If you’re running a Kindle device (except Fire) the Kindle and Mobipocket DeDRM plugin can be configured further to pull books directly from the device.

add serial to plugin

Within the plugin settings you can add the Kindle’s serial number. If you don’t know it, you can gather your 16 digit serial number from Amazon’s website under the Manage My Devices area. After you’ve entered it, click OK and Apply to save changes.

Note that this serial number is only necessary if you are going to pull DRM protected books directly off of your Kindle device.

add device serial to decrypt kindle books

Now there’s two ways to remove DRM using the plugins. The first is by pulling it directly off of the device in Calibre. There should be a new “Add books to library” function that will decrypt the book and make it readable in Calibre for export and conversion.

The second is by adding books downloaded with Kindle for PC. These are stored in the following folder:

  • %userprofile%documentsMy Kindle Content

Just adding them to Calibre should decrypt them.

add booksselect books from k4pc download folder

That should handle removing DRM from your Kindle and other books using Calibre. If you have any questions or comments, please drop them below!

    can you search Kindle for DRM’d files or do you have to remove and re-add them again

    I installed the calibre, dedrm, and already had kindle for pc. I still can not convert any of my kindle books. Especially if it has it is an azw format I can not even read it on the calibre program. I do not know what I am doing wrong. I would like to know exactly how do you pull up the screen on calibre where you can insert the serial number of your kindle device? I can add books to the calibre library onto calibre but can only read the mobi formatted ones. Please help
