Calibre DRM Removal Plugins

Posted by on .

What is Calibre DRM Removal Plugin? Calibre DRM Removal Plugin, known as Alf's DeDRM Plugin tool, is developed to remove DRM from eBooks, including Kindle, Kobo and Adobe DRM. There is no doubt that Calibre's success majorly depends on those varieties of plugins and Alf's DRM Removal plugins are the super stars among them. But many people are saying the Calibre's interface and user-experience are not that friendly for tech noobs. No mention the plugin installation, which would be another challenge for them. To help you use this free DRM Removal plugin smoothly, this article will cover these two issues: how to install DRM Removal Plugin to Calibre on Windows /Mac and how to remove eBook DRM with Calibre DRM Removal plugins.

Part 1. How to Install Dedrm Plugin to Calibre

Step 1. Install Calibre

Calibre is totally free to download and use, click the buttons below you can download the Windows and Mac versions directly.

Download for multiple platforms click here: http://calibre-ebook.com/download

Step 2. Download the DRM Removal plugin

Part 2. How to Remove eBook DRM with Calibre DRM Removal Plugins

For now, this Dedrm plugin can remove DRM from Kindle eBooks (only downloaded to your kindle desktop application and kindle eink device), Barnes & Noble ePub ebooks (Because Nook has changed its DRM scheme, this DRM plugin does not work for Nook DRM any more.) , any ebooks using Adobe Digital Editions DRM (This includes ePubs from Kobo and Sony that are downloaded for Adobe Digital Editions. I have to mention that many vendors have strength their ADE DRM to force readers to download eBooks via ADE4.5 which may caused the DRM removal failure.), and the older Mobipocket and eReader ebooks.

Detailed stepsRemove DRM from eBooks with Calibre

Step 1. To remove DRM from eBooks, you just need to find your downloaded file and add them to Calibre.

Step 2. Once the book has been added successfully, DRM will be removed automatically.

Detailed stepsRemove DRM from Kindle device with Calibre

The above steps show you how to remove DRM from ebook downloaded to your computer directly. If you have books downloaded via Kindle devices, this part will show you how to remove drm from Kindle device with Calibre DRM removal plugin. Please note: Calibre DRM Removal plugin cannot handle ebook downloaded via Kindle device firmware higher than 5.10.2 because they are encrypted with a new Kindle KFX DRM.

Before we start the detailed steps, please find your Kindle serial Number and write it down at first. You will need it later. You can also watch the following video to know how to find a Kindle serial No.

Steo 1. Run Calibre, and find "Preference"-->>Plugins.

Step 2. Then find "File type plugins"-->>Select " DeDRM (6.6.3) by Apprentice Alf....scripts" and then click on "Customize Plugin".

Step 4. Then go back to the main interface of Calibre and plugin your Kindle device. Find the "Device" option at the top menu and select "Show books in the main memory of the device".

Step 5. All Kindle books from your device will be loaded in. Select the book you want to decrypt, right click the mouse and then choose "Add books to Library" . You will see your selected books has been transferred to the main library of Calibre and the DRM has been removed in this process.

If it doesn't work, try to:
1) remove your DRMed books from the library
2) reload Calibre
3) add them again to library

at least this works for me!

Perfect. Everything working. If you have $20, purchasing the Epubor Ultimate (which includes DRM removal as well as eBook converters) is well worth it. It gets rid of DRMed AZW4 files in less than a minute. Drag-drop-done.

The Calibre DeDRM plug-in and Epubor software work well on Win7 64-bit.
You MUST have Kindle for PC/Mac/etc. installed and activated on your PC before either the plug-in or Epubor software will remove the DRM from Kindle books.
If you download other e-books, you must have Nook for PC, Adobe Digital Editions, Kobo Reader, etc. installed for either approach to work.  Both software solutions rely on being able to access YOUR account credentials which were used to encrypt the e-book you have downloaded. This is the only way the e-books with DRM can be decrypted.  Note: This prevents sharing e-book files with intact DRM.
The documentation for DeDRM and Epubor both explain this.  If you can't use these solutions, you probably didn't read the documentation.  Everything is very well spelled out.
Also, Kindle books with DRM that are already added to Calibre must be removed and reloaded for the plug-in to work.  It only works when Calibre loads and processes the book file.

To those of you that are complaining about this plugin not working:

This website's offering an outdated version of the Calibre plugin. Try downloading the latest version from the plugin's official website first before you start complaining: apprenticealf(dot)wordpress(dot)com

Instruction: Run Calibre, and click "Preferences" in the top menu bar. Problem- Running Calibre brings up the Library where I cannot find "preferences". I must be doing something wrong, but what is it?
reply
02/20/2019 06:29:06
If you open up the main Calibre program screen, you will see the PREFERENCES all the way to the top right.

This is the exact same problem that I'm having. When I open the .zip file, I can see the _init_.py file in the DeDRM_tools_6.6.3 in temp folder where the .zip unpacks.

Thinking I'll just get the other software and be done. This used to work perfectly, but sadly it doesn't and the plugin won't install now.

I did the following steps but Calibre still shows the message that books are DRMed.

1) Downloaded Calibre
2) Downloaded the Plug-In --> added it to the PREFERENCES. It sais it is active
3) Restarted Calibre.
3) Downloaded the E-Book in AZW3 from Amazon ("Download and transfer via USB")
4) Added the book to Calibre
--> Cannot open it in Calibre

Do you have some helpful ideas I maybe missed to do? Would be great if you could help!

reply
09/24/2019 08:44:59
If you have downloaded the kindle books from amazon via usb, this book is encrypted with azw3 drm. Please follow this part" Remove DRM from Kindle device with Calibre" in this article. You should enter the kindle series no.
