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.

calibre-advanced-plugins

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.

calibre-plugin-securiy

Finally you can see the success notification.

plugin-install-success

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.

Windows Version Download Mac Version Download

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

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

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?

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.

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!

Hi, I have Calibre 2.24 on W7, and this version does not have the option of installing a plug-in from a file, only from the master list.

I tried to do the "manual" installation from the "Writing your own plugins..." help, with the command line:

calibre-customize -b 1.


and it installed some stuff but came up with the error message:
[Error 3]  The system cannot find the path specified:  u'1.\\*.*'


Presumably this could work if I found the right directory to unzip the Obok files into.
Any help on this?

I find this most frustrating, as I bought a book on Kobo, believing it to be in epub format, which I could read on my various devices.  As it happens, I borrowed the original book from a library, my wife got partways through on her Nook, and I decided to buy it so she could read it leisurely.  Well, of course, I am unable to liberate it from the Kobo, and what is really additionally irritating, that I cannot find the place where she stopped.  I have copied out a sentence from the page where she was on in the Nook, but Kobo is unable to search for a phrase (in spite of suggesting a phrase search), and the Nook version was consecutively page numbered, while the Kobo version restarts the page numbering in each chapter.  Guess how many more books Kobo will be selling to me?

thanks,

A

Hi,

I installed Calibre 2.24 and am able to install plugin from file.

However, for Kobo books, you can download .acsm file from Kobo website at first, then convert acsm to EPUB via Adobe Didital Editions, you can read this guide post: http://www.epubor.com/how-to-read-kobo-books-on-kindle.html

This calibre tool works and doesn't work.  :)

I have it installed on this computer twice.

  WinXP here. Two different user accounts.  Each with Digital Editions, each with Calibre, each with the removal tool installed in calibre.

  One works.  The other one doesn't.  

  I have removed the book from calibre library and then reinstalled it again and it still doesn't work.

  So I know it works.  And I know it doesn't work.

I tried the removal tool thing but that turned out to be simply a trail that led towards an ask for money...

Hi,
I run calibre on a MacBook. I have tried to install the DeDRM Plugin, but I get the following fault:

I have almost 6,800 ebooks that I store and read in Calibre, and I have had Calibre for years. The problem I ever had with it was when I was stupid enough to not make sure I keep the updates current or when I didn't read the instructions correctly. Only a illiterate could have a problem with Calibre. Follow the instructions, and it works well. With Calibre Companion I can get all or some of my books on my Samsung Phone, or it will format the books perfectly to send to my Kindle Reader. Formatting works automatically when it is copied. I rest my case - Calibre is the best, and I choose to ignore anyone who can't use it as computer illiterate. Here's my advice RTFI "Read the F***ing Instructions.
