How to Remove DRM from eBooks Adobe Digital Editions

Posted by on .

Adobe Digital Editions (abbreviated ADE) is an ebook reader software program from Adobe Systems, built initially using Adobe Flash. It is used for acquiring, managing, and reading eBooks, digital newspapers, and other digital publications. The software supports PDF, XHTML (through the nonproprietary EPUB file type specification) and flash-based content. It implements a proprietary scheme of Digital Rights Management ("DRM") which, since the version 1.5 release in May 2008, allows document sharing among multiple devices and user authentication via an Adobe ID.

That's why so many people want to strip Adobe DRM. And this is also the reason why we write this article for you. Three parts are covered here concerning how to remove DRM from Adobe protected ePUB & PDF books, among which the second section is especially important as the key decryption is exactly generated during this process.


Part 1: Check whether your ePUB & PDF eBooks are DRM protected or not.

Part 2: Read your DRM-protected ePUB & PDF eBooks on Adobe Digital Editions.

Part 3: Remove DRM from ePUB & PDF on Adobe Digital Editions.

Video Guide

Part 1: Check whether your ePUB & PDF eBooks are DRM protected or not

Launch Calibre (Windows/Mac), add your ePUB & PDF books and double click the book title to open it. If the following warning window pops, it means that your book is DRM protected. For your .ACSM files, just convert them to EPUB so as to be supported by Calibre.

Or you can open the PDF books with your favorite PDF reader. DRM-protected PDFs will come with a similar alert window.

If you can read your books on Calibre without restriction, they will be DRM free. Just feel free to transfer them to anyone.

Part 2: Read your DRM-protected ePUB & PDF eBooks on Adobe Digital Editions

1. Download & Install Adobe Digital Editions and authorize your Adobe Digital Editions with your Adobe ID. If you don't have an Adobe ID, you can apply a new one.

2. Make sure the ePub & PDF files can be read on ADE!

For EPUB & PDF books from Sony/Kobo/ other stores, refer to how to read eBooks on ADE.

For .ACSM files, refer to how to convert .ACSM to EPUB to read on ADE.

Note: The decryption key will be generated during the reading process. If you failed to read eBooks with ADE, you will be likely to fail to remove DRM as well. To solve this problem, you have to delete all your books under ADE folder and redownload them under the newly authorized ADE.

Part 3: Remove DRM from ePUB & PDF on Adobe Digital Editions

1. Download and install Epubor Ultimtate.


2. Launch Epubor Ultimtate, it will automatically detect and upload your books saved in ADE's default folder. As you can see, all the books here are listed on the left side.

remove DRM from EPUB file

If the program doesn't detect your books, you can manually set the input location by "Settings" -> "ADE". You can also just drag those eBooks to the program's interface.

To check the output books, you can click "Decrypted" to open the output folder. Or you can also right click on the title in the interface and choose "Explore Decrypted File", then you will see the decrypted DRM-free eBooks.

Some Good Tips for You

1. The default location of ADE:

For Windows: ...\My Documents (or Documents)\My Digital Editions\...

For Mac: Users/ ... (Your computer name)/Digital Editions/...

2. Problem with authorizing ADE:

An error "problem decrypting session key" may occur if you use different ADE versions to download ACSM files or open eBooks. In this case, you have to delete all your downloaded books under your ADE folder and redownload them with the authorized Adobe ID again.

3. Win 7 or Vista users:

This guide mainly applies to Win XP and Mac. If you are using Win7 or Vista, please right click on the program icon and choose "run as administrator".

4. Convert Books with Calibre:

If you want to convert the books, use the best eBook manager and converter Calibre!

5. Remove DRM from Kobo eBooks:

Since Kobo eBooks are also protected with Adobe Adept DRM, you can use this method to help you. But here is an easier way for you to remove DRM from Adobe Digital Editions.

07/20/2014 12:04:08
Wow... Thanks so so much!
08/14/2014 05:05:49
It works!  However this prog is the trial version.  If this were a freeware, the world will be a better place......
08/14/2014 19:41:37
Thank you for the kind words about this post. However, the company needs money to run and to expand, sorry for cannot provide this program for free.
10/9/2014 04:37:00
Thank you. Perfect.
10/29/2014 07:33:11

Perfect, With the Trial Version I've been able to decrypt Adobe's 3.0 DRM and FINALLY print the book.

Thanks a lot.

11/3/2014 09:09:27

Thank you so much, this works perfectly and I'm now able to print my books.

Again, thank you for a helpful post!!!

01/18/2015 00:37:04
thanks it worked perfectly :)
04/7/2015 07:16:32
I took a course and in these course they sent me a ebook for Adobe Digital editions I installed without Adobe ID i just permit in the computer, so is there a way to break tha DRM ? Please someone help me
04/8/2015 20:11:18
I guess it's sort of a "rented" book, and it's not guaranteed to decrypt successfully. However you can use our free trial to handle it before placing an order.
04/11/2015 13:53:33
If you're removing DRM to read a book on your own device, great.
However, if you're trying to open a stolen book, please remember that authors work as hard as you do at your day job. Would you want to not get paid at the end of the day for your work? Would you show up at your desk knowing someone was going to rip you off? How could you possibly enjoy reading their efforts with this in mind? You are a reader. You are a good person. Do not steal books.
04/11/2015 21:07:52
You are correct!
The software just help you backup your books, not others!
04/26/2015 09:15:24
Didn't work for me. Pressing the button, Finder window opens, nothing happens.
Book bought on Google Play, opens in ADE.
04/26/2015 18:40:48

You don't input email address, so we can't contact with you.
This method has helped thousands of people resolved their problems, it's must be helpful with you.

Please don't copy the file anywhere, just click .acsm file with Adobe digital editions to download ePUB/PDF files, and make sure you can read all books with ADE, then drag all book files to Epubor software, all done.

If failed, please delete all book files, and download again.

Hey it does not work on Win 8...
06/11/2015 00:30:58


Win 8 has two modes, including tablet mode and traditional computer models.You can operate in traditional models,and it will work

06/11/2015 07:24:19
I did not get it. Can you elaborate a little bit? How to use the traditional mode? Many many thanks!
06/11/2015 19:26:46
Under Win 8 there two operation modes, one is the "tablet mode", which you can only install apps from official appstore, another is the "traditional mode", which looks like Win 7, you can install program with an .exe file.
07/1/2015 04:31:13
i got the full version and it works like a charm. but i was still unable to print. hope you can help me.
07/2/2015 18:53:52
Can you tell me more details about your problem?
09/8/2018 10:51:09
I guess the file you try to print is epub, not pdf. Please convert the epub file to pdf with Epubor Ultimate and then print it.
07/12/2015 15:01:22
This is awesome, if it doesn't work for you then you did something wrong.  I downloaded and had the PDF DRM free within a minute, through it in my dropbox and opened it on my ipad.  Great program!
10/2/2015 11:27:39
Works like charm. Thank you!
10/7/2015 23:42:02
Thanks for using our software. If you like it, don't forget to recommend it to your friends.
10/30/2015 18:37:53
It worked!n I can finally have access to an electronic version of my very own(!!) book manuscript without DRM restrictions. Thank you for helping put a stop to all this madness!
01/21/2016 00:41:19
Worked perfectly on Windows 10 to unlock an overly restrictive school PDF document! It is shame that the library's online book reader and that Adobe digital editions provide a very poor user experience. Ctrl+ doesn't zoom and Adobe only provides presets such as full page, 1.5x, 2x, 4x. What about 1.25x? The online view makes the text blurry when using the built in font tool and even then the font choices are: small, medium, and large. I don't like removing copy protection...but the restrictions force us to do so. Thank you!
02/17/2016 17:08:06
Thanks so much!! I needed to print a book in order to work with it for my Master's thesis... I need to make annotations, underlining and write down comments, which I wasn't able to do with the digital version.
03/6/2016 17:56:25
Oh god, it works! And I nearly cried that I will have to read that 316 pp book costing me 30 euro on ADE supershitty interface...
03/11/2016 14:03:12
This is absolutely amazing. I don't understand why there are negative comments below.
But it worked perfectly on my files. I just can't say enough how helpful this is. Hats off to the developer for making this free too.
04/8/2016 07:55:28
thanks. worked perfectly
05/11/2016 02:09:27
Does the DRM remover need an internet connection? I intend to break the DRM on a file only to be able to read the protected file with Adobe Reader instead of Digital Editions, but I worry that the DRM remover intercepts the file I broke DRM on and used it for other purposes.
06/27/2016 11:42:49
Me ha funcionado a la perfección.
07/5/2016 05:44:06
shows drm removed, file still no printable.
09/8/2018 10:45:21
If the DRM has been remove, but still unprintedable, you may need to convert the acsm from epub to pdf and print it.
07/26/2016 01:54:39
This software is amazing and so easy to use! Thank you, great service
09/8/2016 19:30:57
Amazing, worked perfectly!  Index shortcuts also works.
01/19/2017 01:04:16
I am using ADE 4.5, which the library from which I borrowed the book requires. Calibre's DeDRM plugin says there is no way as of Oct 2016 to remove ADE 3+ DRM. I tried a couple on-line pdf to docx converters and they all fail. Can your program do this? Thank you.
01/19/2017 01:29:03
P.S. to my previous comment: The DRM prevents the pdf from being opened in anything but ADE, and it also deletes itself 2 weeks after it was borrowed (I borrowed it today).
02/3/2017 12:46:05
Great program. Works flawlessly...thank you! <)
04/12/2017 20:56:25
Thank you so much. Worked perfectly.
05/7/2017 22:55:09
I like it very much.  One question; how come when I drag a book to remove DMR, most of the time, it shows a generic book cover?  The book cover shows up in Adobe before and after I remove the DMR.  
06/29/2017 12:12:07
THANK YOU! It worked perfectly.
07/13/2017 16:44:40
It is our great pleasure!
07/1/2017 22:46:18

Doesn't work woth ADEPT (Adobe Digital Editions) DRM.

I downloaded this software, and it failed to decrypt DRM of Adobe Digital Edition.

I e-mailed them reagrding this, first they gave me a laundry list of things to do, did all of it, and it still did not work.

I e-mailed them futher, and they point blank told me that their software does not work for the DRM I tried to decrypt, thank you for the answer, but this software couldn't meet my decrypting needs, i will go as far as saying this software is incompetent for the price it charging.

This was their e-mail answer:

Hi there,
Thanks for using Epubor software.
Epubor software can only support ebook purchased from mainstream ebook stores like Amazon/Google Play Book/Kobo/Nook, etc. We don't promise to remove DRM from books purchased other sources. We are sorry for the inconvenience. By the way, rented books are also not supported by Epubor software.

Best regards,

Thank you for your answer, however, please include in your FAQs the limitations of this software so that individuals purchasing this may know.


02/11/2019 09:50:56
Thank you for your suggestion. We have included all the vendors in our product details and will add it to our FAQ as you suggested.
