Calibre DRM Removal Plugins

Posted by on .

Calibre's success majorly depends on those varieties of plugin in my personal point of view. No-doubt the 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.

Today I am going to cover this problem: How to install and use Calibre DRM Removal plugins.

1Install 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

2Download the DRM Removal plugin

Download the DeDRM Plugin V6.08 here: http://download.epubor.com/DeDRM_plugin.zip

GUI version for Windows | GUI version for Mac | GUI version for Linux

3Install the plugins to Calibre

Run Calibre, and click "Preferences" in the top menu bar, then look at the bottom of the new window, you can see "Plugins" in the "Advanced" area.


In the plugins center, please click "Load plugin from file".

calibre load plugin

Find the DeDRM plugin you downloaded in the step 2, and click "Open". The Calibre will warn you about the security risk, click "Yes" to proceed.


Finally you can see the success notification.


Back to the Plugin center you can see the plugin information in under "File type plugins".


Now the plugin is installed successfully, you can use Calibre to handle DRMed eBooks.

4The easier way to decrypt eBook DRM

Epubor provides a software called "All DRM Removal" which can remove DRM from Amazon Kindle, Adobe Adept(including Kobo, Sony and Google eBooks), Barnes & Noble, Mobipocket and eReader eBooks.

With this program you need not to download or install Calibre and the plugin. Just download and install the All DRM Removal, you can decrypt all the books listed above.

In addition, it only requires you to click one button, then you can remove the eBooks DRM. From all aspects, this way is far more easier than Calibre and the plugins.

All DRM Removal software free download:

I get an error from python when I try

All DRM Removal plug is cripled (and lame).  No mention of $35 price tag until it's installed.  No more epubor for me.

5 Star Rating was an error.  I would give a minus rating if it were allowed.

doesnt work

I had the same problem, it didn't works, but the solution is easy, just remove completly Calibre from your PC, then connect your account with Adobe Digital Editions (if is not connected) then install again Calibre with all them pluggings and test it again.
I dont use Kindle, but i think is the same way to delete DRM to them.

I've run Calibre together with Alf's deDRM on a Macbook Air running Kindle for Mac for 2 years now quite reliably. I particularly like that Calibre converts anything to anything else when I lend a book to a friend that can't read whqtever the format is. One nuisance is that Kindle don't name the book file with the title. It's just random letters. So what I do is sort the Kindle purchases in order of time and the new purchases rise to the top to copy over to the designated input folder for Calibre. And Calibre is really good about duplicates anyway, so it's easy to keep.

One complication for me is highlighting. Although Kindle won't print or copy, it does highlight nicely. Calibre won't highlight though it does copy and print. Kovid says on his site that highlighting is a feature he won't add to Calibre. Adobe does highlight, but is unstable, I've lost portions and whole book underlinings. Sony reader is stable so I use Sony when I want to underline. How odd to have to carry a toolbox just to read.

I spent 4 hours - user of Calibri for many years - updated to newest and could NOT get DeDRM Plug in to appear no matter how many times downloaded / exploded / loaded into Calibre per all instructions (PCs running WinVista or Win7).
I'll try other option now. Years ago on WinXP had a simple program called DRM Removal (or similar) - worked perfect and converted DRM books instantly. I'll look for that too.
Good Luck!

If you cannot handle Calibre, you can just use this DRM Removal tool, www.epubor.com/drm-removal-tools.html

Oops! That 5-star rating is a default - I forgot to change to "less than 1".

Thanks Hyde for response. Sorry for confusion - I love Calibre and have used it many years. The DeDRM programs for PlugIns to Calibre did not work per instructions on this site. I can't find original comments right now.
I did find and download a program that worked perfect in 2 seconds on my Adobe Digital Ediion book (translated to MOBI for Kindle).
It's called epubdrmsetup - perfect!
Thanks again for your hint, and I know can't beat Calibre.

How about try Epubor Kindle DRM Removal?
12/10/2014 12:59:16

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!

El proceso fue fácil y lo logre, pude quitar el DRM
12/22/2014 05:26:00
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.

Spent money on this, doesn't work.

These reviews are fake and created by the makers of this site. This is a scam! Avoid this at all costs.

Removing DRM doesn't work, I've been trying for the longest time using these lying programs. Customer support won't reply to me after I sent an email telling them this program is failing to function.

Please, avoid!

Does not work. Not even a little bit. Just in case you're thinking about trying this...

If you failed with Calibre DRM Removal plugin, you can have a try with Epubor All DRM Removal.

i have the QT4 message on MacOsx
To resolve the issue :
Download an old version of Calibre (1.40 for exemple)

Copy the app on the desktop (not on the application folder) run it and the extensions works for me

The plugin DeDRM does not work and the
All DRM Removal has also not worked.
03/16/2015 19:35:27


Our All DRM Removal can definitely help you remove Kindle, Nook and Adobe DRM. Can you tell me where you purchased your books and the format of your books?

03/16/2015 03:57:49
sorry for my comment before.
I was in the wrong directory from the removed file.
It has worked correctly.
