So we can't read those Kindle books on a Non-Kindle eReader or Kindle app. What's worse, we can't even share Kindle books with our families and friends. Though we have paid for our Kindle books, it seems that we don't truly own them. It's really a pain for eBook lovers, right? But how can we solve this problem? In fact, the best way is to remove DRM from Kindle books. In this article, I will show you a free Kindle DRM Removal--Calibre Plugin, which can help us remove Kindle DRM with ease.

FAQ: Failed to remove Kindle DRM with Calibre
I cannot remove DRM from the Kindle books downloaded from Kindle for PC/Mac or from my Kindle device. Why?

Earlier in 2019, the Kindle has released a new Kindle KFX DRM. Your Kindle eBooks will be encrypted with this new Kindle KFX DRM if you download Kindle eBooks via Kindle for PC/MAC version 1.25 or higher, or Kindle device with firmware higher than 5.10.2.

Now Calibre can not directly handle this new DRM scheme if the Kindle books are downloaded from v1.25/v1.26 Kindle desktop app and higher version.Therefore, the current solution is to downgrade your Kindle to older version, disable KFX support in the latest version Kindle deskotp, or download from Amazon site with Download & Transfer vis USB. The following are 2 solutions that are 100% working.

Solution 1 Downgrade Kindle for PC/Mac to Older Version

Solution 2 Disable KFX Support in Kindle for PC/Mac.

Solution 3 Download & Transfer via USB on Amazon.

Far, far too complicated. If a one-click drm removal that requires no serial number cannot be developed, why bother?

We just want to list all the options. It is for you to make the decision which method to choose. Different people may choose different methods.

Download the software for free, but it won't work (at all) until you buy a license. This is just deceptive marketing speech. It pisses me off to be lied to, and to have a company try and trick me. There is no way I would ever use or recommend your product.

I will not reward dishonesty!

Thank you for your comments. The dedrm plugin is totally free. You can choose to use this free software.
For the Epubor Ultimate, it is the paid software with free trial version.

You should have been honest and said that it's not free. Very misleading.
02/15/2022 17:10:05
And you can't call it a "free trial version" when you only give back 20 % of the text in the trial :(

Epubor cannot be opened on Mac.  Unidentified developer

I have had the same error warning come up each time that I try to install the tool - theplugin -n c:\\users\mdgri\\Ddowlmoads\DEDRM Tool 7.2.1(4)zip is invalid. it does not contain a top level_int_py file

any suggestions please as have lost whole catalogue of books to this

Inside that zip file there's another zip file called "DeDRM_plugin" without any version number. That's the one you're meant to add.

DeDRM Calibre plugin "v7.2.1 — Full Release" is not working :(

One detail that's missing from the instructions. If you're trying to back up your ebooks from your kindle then you need to customise the plugin and add your kindle's serial number. Then you download the ebooks from Amazon with the USB transfer option, and that will work.

Thank you for your supplementary explanation?
