Convert ACSM to EPUB and Remove DRM

We often get an .ACSM file after purchasing an eBook online, but it’s not the eBook file. Here I will tell you how to convert ACSM to EPUB and PDF, then strip eBook DRM for reading on various devices.
To convert ACSM to EPUB you just need to follow these simple steps:
- Install Adobe Digital Editions (ADE)
- Authorize with your Adobe ID
- Open the .ACSM file via ADE
- ADE would save the .acsm to .epub (or .pdf)
- Use EPUB DRM Removal to remove DRM from the EPUB
Below is the step-by-step guide.
How to Convert ACSM to EPUB books
Step 1 Download Adobe Digital Editions 4.5 (ADE) .
Step 2 Register an Adobe Account and authorize ADE with your Adobe Account by clicking “Help”->”Authorize computer”.
Have installed ADE before and wanted to switch to another account?
please press “Ctrl + Shift + D” (Mac users press “Command + Shift + D”) to wipe out the formal authorization information and re-authorize with the correct Adobe ID.
Step 3 Open .ACSM with authorized Adobe Digital Editions to download eBooks.
Double click the .ACSM format file you downloaded from the online library, then it will be opened with Adobe Digital Editions as default and start downloading.
Tips: If your .ACSM file is not opened by ADE as default, right click the file and select “Open with“ -> “Adobe Digital Editions 4.5 “.
Output path of your EPUB file is:
For Windows: …\My Documents (Documents)\My Digital Editions …
For Mac: Users/Your computer name/Digital Editions …
You can also switch to “File” Menu -> “Item Info” -> “Location” to check the location of your downloaded EPUB book.
After downloading the eBook, you can delete the .ACSM or back it up for downloading the eBook later.
We can read the converted EPUB eBooks on Adobe supported devices like Sony eReader, Kobo reader, Android Devices (with reading apps like BlueFire installed) etc. Just copy the converted EPUB files to the specified eBook folder of your device with the USB cable connected to your computer. Make sure your eReader is authorized with the same Adobe account, otherwise you will be prohibited to open the EPUB books.
However, you can’t directly read the books on Apple Devices (iPad, iPod, iPhone with iBooks) and Amazon Kindle titles because they don’t support Adobe DRMed books unless you can install compatible ADE app. So we have to remove DRM from the eBooks, then transfer them to anywhere as you like. Here is the best software for removing DRM from Adobe DRM protected ePUB .
How to remove DRM from ACSM (EPUB)
Step 1 Download Epubor Ultimate .
Step 2 Run this program. If your EPUB files are converted from ACSM as the guide above, the program will find your EPUB files automatically and display it in the left column. You can simply drag the file from left side to right side to remove DRM.
You can right click on the added file and choose “Explore decrypted folder” or click “File”->”Open decrypted folder” to get your DRM free EPUB books.

I have read this information before with Adobe digital. Perhaps Adobe Digital is not installed corrctly.
I did not see a software to remove DRM. You mentioned being the best software but did not give the name.

Does Epubor only allow you to access a portion of a book when you use the free trial version? I tried it with a book that has 248 pages and only the first 50 pages converted.

The trial version will help you decrypt 20% content of each book.

Thanks for this guide. However, I tried getting an ID but never received an email confirmation from Adobe. So in the end I tried ‘activate without an ID’ and it worked fine. So maybe you don’t need to bother?
I also didn’t bother with DRM for the two books I converted. They seem to work fine.
Thanks again.

Your instructions are easy to understand and I have followed them. My problem is adding the ebooks to Calibre. I cannot open them there and I also am unable to download from ADE to my Sony reader. I am not computer literate so many things are not as simple as they seem. I read that I should be able to download to my reader from ADE but I see nothing to tell me that I can.
Epubor.Fors

Hi Clemira,
We are very sorry for the late reply.
Calibre is not able to add your books because your books are DRM protected, Calibre is only able to handle those DRM-free eBooks.
Now have you get the .ePub files or still .acsm files?

“the program will find your EPUB files automatically.”
I bought a Google E-book (acsm file) and opened it in ADE, but apparently the file hasn’t turned into an EPUB file; instead, it appears as a .pdf file instead. I tried putting “.epub” at the end of the file name, but the program failed in removing the DRM.
How do I solve this???
Jonny
01/23/2014 23:30:47
Hi Louise,
Yes sometimes the .acsm will give a PDF file.
Then you need to use our Adobe EPUB&PDF DRM Removal, it can handle both EPUB and PDF files.

Adobe Digital Editions fails to download epub content from acsm, just says about some license error and server error with something about unknown filetype.
Authorization is ok, tried that to some sample book (acsm) from ade website.
this drm is frustrating, you can’t read the book you just bought.. :/
Epubor
01/21/2015 20:51:26
Hi,
This problem happens when you are not connecting your Adobe account with the account of the online store where you bought this book.
I would recommend you contact the book store’s customer service for this issue.
doh
01/22/2015 04:25:54
So what’s the proper way to connect adobe account to let’s say mat google account? I may as well create new adope account cause just made one yesterday for this purpose only.
So if I start with clear desk, what should I do to make sure things will work?
Epubor
01/22/2015 20:02:45
Different online retailer provides different ways, the best practice is to contact the online retailer’s customer service for help.

Did that, contacted to google, and thay said it is font which is causing problems and they are trying to solve problem. No timefrime tough. They also offered option to get refund from book.
This shows that drm is crap, if you cand download book with some font by using acsm file, but you could do it other way just fine. Sure there are lot more reasons why drm is crap, but…

I don’t have a good command of English…
I have tried to open that acsm file, but it’s always appearing a window saying: “Error! Check activation.”
I’ve got either Adove Digital Edition 2.0.0.0 and 4.0.3.0
What do I have to do?
Alen
03/31/2015 18:32:47
Use the latest version of Adobe Digital Editions, and authorize with your adobe ID, then click .acsm file do download EPUB books.

For decrypting Adept ePUB&PDF books:
1, Install Adobe Digital Editions (ADE) on your computer and authorize your computer with Adobe ID.
2, Click .acsm file to download ebook file, make sure you can read the EPUB/PDF books on ADE.
3, Run Epubor software and add the EPUB/PDF books from default ADE content folder to software’s main window, and remove DRM.

Hi,
Glad to hear that your problem has been solved.
The Kindle DRM Removal only supports Kindle formats, but you are trying to remove DRM from EPUB with it, so it says “Don’t support the format”
Thank you !

I have a computer that is not compatible with ADE 4.5 and the older ADE versions are incompatible with my .acsm file. Is there any other way to convert the file so that it is readable?
Ann
08/4/2016 02:44:05
1. Ctrl + Shift + D, erase authorization.
2. Delete your files under “My Digital Editions”.
3. Download the old version of ADE, log in with your Adobe ID(authorize).
4. Download your ACSM file again and drag it to the ADE.

Thanks a bunch this worked perfectly! Ended up buying a book on Google Play and then was at a loss as to how to get it on to my Kindle! Your guide helped me a lot because I’d never seen a .acsm file before and had no idea what DRM locked books were! Quick question: this AllDRMRemoval software: I’ve clicked free trial for now, how long will this trial last?

The DRM removal seemed to work just fine, but the de-DRM pdf I got has the following tezt
“Your ebook has decrypted.
The TXT file just save 20% of ebook content.
Please register the software, then get full content and the valid ebook
format.”
Only a fifth of the book is actually there. Is there any way to get around this?
Epubor
01/24/2018 14:50:49
That’s because you are using the trail version. If you want to get the whole content of the decrypted book, you need to purchase the license version.

It somewhat worked, what you trade for getting rid of the DRM, you get ugly xhtml text formatting or no formatting, and it only converted 1/3rd of the book, rather disappointing.
Epubor
03/8/2019 11:51:46
You are using the trial version. It will decrypt and convert 20% content of each book.
Here is the solution:
Solution 1: Buy the full version.
Solution 2: Ask for customer support team to ask for temporary license.
Solution 3: Contact editor team to help translation the software or one article in exchange of a free license .

Following these instruction, the “decrypted” file was just a txt document. Is that due to a limitation of the trial version or does this not convert DRM protected epubs to pdf?

Hi: I have a fully licensed version of Epubor Ultimate v3.0.12.610. I’m trying to decrypt and convert a new book I just downloaded to Adobe Digital Editions. ADE has my login and account correctly set up and I’ve successfully converted previous ACSM files. With this book I get an error message: AdeptDRM failed!
To test, I again successfully converted a previous book from last week so it’s only this book, Any suggestions you have would be appreciated.
Thanks. –George

It does the work. And I thought USD 30 is okay. However, a little expensive for just removing the DRM. USD 20 is a more ‘normal’ price for a removal tool. But then, and I’m getting really annoyed by these practices, it is only for a 1-year subscription. If you want a lifetime subscription, it costs USD 55. For a removal tool. Are you serious?

I would buy this if it worked properly, but when I tried out the trial version, it converted the ePub books I’d downloaded via Adobe Digital Editions to plain text files. I need an ePub file without DRM. A plain text file is no good to me!
Epubor
11/2/2020 10:34:24
Thank you for using our software. That’s because you are using the trial version. If you use the full version, you will get the full content in its original formatting, not the text file. Please don’t worry. We have 30 day money back guarantee. If you are not satisfied with our software, just request the refund before that.

It was certainly incredibly generous of people like you to present without restraint what exactly many of us would’ve sold as an ebook to make some dough on their own, primarily now that you might well have tried it if you wanted. These strategies likewise served to provide a fantastic way to fully grasp the rest have the same passion just as mine to grasp more and more related to this issue. I know there are several more pleasant sessions up front for those who read through your website.

I purchased epubor ultimate and was able to successfully convert 31 purchased kindle books to epubs for my archive. For the most part your sw worked well and I’m satisfied. However, I have encountered ADE issues with books downloaded from my library. I have installed ADE 4.5.11 on my Win7Pro pc with sp1. If I download several epub books from my library and try to import the .acsm files to ADE (about half the time) I get an error that it can not open the .acsm file in my c:\users\…\downloads folder. I’ve tried uninstalling ADE, removing and reauthorizing, upgrading my NETF to 4.8, deleting the C:\Users\…\Documents\My Digital Editions folder and using a different pc setup. Still 2 or 3 out of 5 books fail. I then cleaned up ADE 4.5.11 and installed an old version of ADE 3.0 + authorization and I can download/import 5/5 books successfully. I’ve tried ADE 4.5.11 on win10pro and it works fine. I can not figure out what’s wrong and my epubor ultimate won’t accept a .acsm file.
I know I can just leave ADE on 3.0 and forget it but would still like to know what is causing the error.

Hello, thanks for your message.
This is due to the security settings for your Mac. By default your security preferences only allow installation of apps from the Mac App store and identified developers.
To solve this problem, go to System Preferences>Security & Privacy. On the General tab, click on the little lock icon in the lower left corner to unlock the general preference pane. Then select the Open Anyway radio button beneath Allow applications downloaded from.
Any other questions or concerns, pleas feel free to contact u s via support@epubor.com .

I am a student trying to download digital books from the Uni Library. I have downloaded the books in the latest Adobe Digital 4.5. while I am trying to decrypt the book using Epubor Ultimate full edition (drag & drop), this is giving me an error message (DOES NOT SUPPORT EBOOK- click here how to remove DRM from ACSM file). The Source file in Adobe Digital Book is in ACSM, why ultimate full epubor full edition is unable to decrypt the file?

Hi,
I’m sorry that we can’t make sure that our software can decrypt all the books you downloaded from your University library, but you can test some books with Epubor Ultimate. If it failed to remove DRM, our software doesn’t support it.
Epubor Ultimate can support decrypting and converting the most books you purchased from common websites like Amazon Kindle, Kobo, Barnes & Noble Nook, and so on.
Any other questions or concerns, please feel free to contact us.
Best regards,
Epubor Team

I purchased epubor ultimate, it unable to convert .acsm files to PDF. I have encountered ADE issues with epub books downloaded from my online library. I have installed the latest Adobe Digital Edition (4.5.11). I download several epub books from my library and try to import the .acsm files from my epubor folder to ADE, it does not automatically load the file in the ADE software under the ADE Tab, I then have to manually load the file from the source folder to the ADE software. After I loaded the file to the ADE software, I tried to convert the .acsm file to PDF, I get an error that it can not be converted due to the DRM security feature (error message to remove DRM the .acsm file).

Hello,
May I ask where you downloaded and purchased this book?
I’m sorry that our Epubor Ultimate does not support the e-books you rented from a Library.

HI–I downloaded an ascm file from cloud library, to read offline; Adobe Digital Edition 4.5 wouldn’t authorize it.
