As we know, Kindle books we buy from Amazon are always protected by DRM. 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.
Free Kindle DRM Removal: MSIXKFXArchiver + Calibre KFX-input Plugin
With the release of the Microsoft Store Kindle app and the retirement of the legacy Kindle for PC, a new method for free Kindle DRM removal has been released by Satsuoni. It has also been packed into the DeDRM_tools package; however, this Kindle DRM removal process does not rely on Calibre itself. That said, using this method still relies on the Calibre KFX Input plugin, which functions to convert the generated kfx-zip files to KFX files for later conversion. Let's see how it works.
Step 1: Download needed tools: Calibre and kfx-input plugin
Calibre Download KFX-input Plugin Download
Step 2: Install the KFX Input plugin in Calibre
We have shared the full details in this post: How to install the KFX Input plugin.
Step 3: Download DeDRM_tools.zip and extract Kindle books as KFX-ZIP files
First, make sure your Kindle books have been completely downloaded via the Microsoft Store Kindle app.
Unzip the DeDRM_tools.zip file and locate MSIXKFXArchiverMobi1_16118.exe. Run it, and a command window will pop up showing the decryption process. Once finished, you will get a folder named "archived_kfx".
All downloaded Kindle books will be extracted as KFX-ZIP files. Now, simply drag and drop them into Calibre (make sure the KFX Input plugin is already installed), and the Kindle books will be imported as DRM-free KFX files.
From there, you can convert the KFX files into EPUB, PDF, DOCX, or any other format you prefer.
A Simpler and More Effective Way to Remove Kindle DRM (both on Win and Mac)
Does the DeDRM plugin method seem a bit complicated? Don't worry. I want to share a much simpler tool with you: Epubor Ultimate. It is currently the best eBook DRM removal and Kindle converter tool on the market.
It is super easy to use. First, download your Kindle books using the Microsoft Store Kindle app. Then, open Epubor Ultimate, and your downloaded Kindle books will automatically appear in the left panel under the "Kindle" tab. Simply drag and drop them to the right side, and the Kindle DRM will be removed instantly.
1. No need to install additional DRM removal plugins.
2. Much easier to use than Calibre, thanks to a cleaner, more intuitive interface.
3. Automatically detects and loads your books into the software—no manual adding required.
As a disclaimer, I should explain that my reason for taking DRM from books is to allow me to rename and order books on my e-reader how I would like them. For example an author may write stand alone novels but also series , I like to prefix my series of books and number order them, or simply to remove annoyingly long subtitles like – a stunning psychological thriller! or similar. It is not to share the books with other people other than those people I would allow to read my e-reader. I would recommend Epubor Ultimate to anyone who needs to easily gain full access to the ebooks that they purchase – it really could not be easier to set up or use. - ady briggs- A happy customer
As the image shows, Epubor Ultimate automatically recognizes your existing books and displays them in the left column under the Kindle tab. Simply drag them from the left to the right-hand pane, and the Kindle DRM will be removed instantly. It’s a far easier solution than using Calibre plugins, wouldn’t you agree? Download it now to give it a try!

Free Kindle DRM Removal: Calibre DeDRM Plugin (Legacy Method)
Step 1. Install Calibre and DeDRM plugin
Before removing Kindle DRM with Calibre plugin, you need to install both Calibre and the DRM Removal Plugins first. If you have already done it, just skip this step.
Download: Calibre
Download: DeDRM_tools.zip(v10.0.9)
The DeDRM_tools.zip you download from Github should be unzipped. After you unzip it, you will get a file DeDRM_plugin.zip which is exactly the file you should install to Calibre. Remember to install the DeDRM_plugin.zip instead of the DeDRM_tools.zip.
Then run Calibre, click "Preference" >> "Plugins" >> "Load flugin from file" >> add the DeDRM_plugin.zip file to Calibre. Follow the procedure and you'll find the DeDRM plugin has been added under the "File Type" option.
Note: You should also install the kfx-input plugin to calibre.
After installing them successfully, it's time to remove Kindle DRM.
Step 2. Remove Kindle DRM With Calibre DeDRM Plugin
First, make sure you have downloaded your Kindle books to your computer. If not, there are 3 ways you can try to download them:
(1) From Kindle for PC desktop app (V2.4.0);
(2) From Amazon official website(no longer works).
(3) From Kindle e-ink device (firmware lower than 5.18.5).
(4) Newly Supported: From kindle for PC (v.2.8.0/2.8.1/2.8.2/2.8.3)
How to remove drm from Kindle for PC desktop app (V2.4.0)
1Add books.
When the Kindle books are prepared, run Calibre, click "Add books" to upload your Kindle books (the .azw format file) to Calibre or just drag them to it.
2Remove DRM from Kindle books.
If your books are downloaded from Kindle desktop app, Amazon site or Kindle device, the DRM will be automatically removed when you upload books.
How to Remove DRM from Kindle for PC 2.8.x (v.2.8.0/2.8.1/2.8.2/2.8.3)
Another fact is that the free kindle dedrm plugin won't work if Kindle for PC app updated to v.2.8.0/2.8.1/2.8.2/2.8.3. You will get the error like "Failed to decrypt KFX DRM voucher with any key" and the imported kindle books are turned into KFX-ZIP format, still with drm protected. If you have updated your Kindle books to the latest version, try this KFXArchiever method developed by Satsuoni.
How to Remove DRM from a Kindle E-ink Device (Firmware Lower Than 5.18.5)
Note: You need to configure the Calibre DeDRM plugin for your Kindle e-ink device first.
Go to Preferences >> Plugins >> Search for “DeDRM” >> Customize Plugin >> Kindle eInk Books, then enter your Kindle serial number.
For Kindle device users, simply connect your Kindle to your computer using a USB cable. Calibre will automatically detect the device and display it on the top menu bar. Click Device to view the Kindle books downloaded to your device, then add the books to the Calibre library to remove Kindle DRM.

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!
For the Epubor Ultimate, it is the paid software with free trial version.
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
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.
Purchased and returned the ebooks in 5 mins????
If I add a DRM protected book into the Calibre library it says it cannot open it due to DRM protection.
Any ideas?
thanks
Steve
Hello,
Thanks for your comment. I'm sorry that we can't make sure taht the DeDRM plugin of Calibre can decrypt all books protected by DRM.
If this plugin does not work for your book, I suggest that you can use our Epubor Ultimate, please test your book with the free trial version.

Las indicaciones que da el autor funcionan sin problema, solo hay que leer y seguir el procedimiento indicado, entre otras cosas por ejemplo: 1) instalar una version de KINDLE para PC anterior a 1.25 y 2) usar luego CALIBRE (con los complementos suministrados)para obtener el resultado buscado.
Gracias!!!!

The indications given by the author work without a problem, you just have to read and follow the indicated procedure, among other things for example: 1) install a version of KINDLE for PC prior to 1.25 and 2) then use CALIBRE (with the supplied accessories) to obtain the desired result.
Thank you!!!!
I have done the free trial. As a demo of what is possible, it is good. Simple, I like simple. Okay, it choked on a massive file, but the rest were automagically completed.
Unfortunately I'm retired and too much month at the end of the money was on the 2nd. Bummer.
But, thank to the pointers, device and step by steps, I was able to get the alternative method to work. "It has only taken me 4 plus hours. to get the work around to work around. (Tangent: I do not like Windows 11, and I sometimes feel my laptops aren't real computers.)
But the people ae epubor.com are doing great work, and I wish them continued success.
I don't know if the software work, and I can't know because I won't buy a product before I can test it.
The so called "free trial" is not actually a trial, it's a bait. Sure the interface of their software says "book converted" but depending on your book (image heavy books for exemple) it's not enough to see if it really worked.
A real trial version should allow FULL access to ONE OR TWO books, to show it works. And THEN only ask for your money.
I'm not paying, not upping my rating until a real free trial is offered.
(3) From Kindle e-ink device (firmware lower than 5.18.5).
This option will not be available as of May 20, 2026 for older Kindle issued before 2012.
Amazon is desupporting the transfer of ebooks to old Kindle devices through wi-fi. The Kindle devices affected are:
Kindle 1st and 2nd Generation,
Kindle DX and DX Graphite,
Kindle Keyboard,
Kindle 4,
Kindle Touch,
Kindle 5,
Kindle Paperwhite 1st Generation
Basically after May 2026 these devices can only read the books already present and no new books bought on Amazon store can be tranferred to them. They also cannot be reset bricking them if any issue occurs.
The only way to save new books to these devices is through Calibre with no eDRM.
Amazon mentioned they will remove eDRM from their ebooks if the publisher/author authorizes it.
This might give access to a few books.
Note however that you cannot download the books on your PC directly anymore. That feature has been removed from Amazon since May 2025. So the only choice is to get the ebook on the PC using K2PC app.
