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".
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.
Remove DRM from Kobo ACSM
If your ACSM files are downloaded from Kobo ebookstore, here is an easier way for you to remove drm: Kobo DRM Removal. It will automatically detect your ACSM files that you have downloaded to computer. No need to use Adobe ID to authorize your files any more.

I did not see a software to remove DRM. You mentioned being the best software but did not give the name.
Thanks for viewing our site!
The page has introduced the software, here is the link:

Enjoy
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.

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?
Hi, Anil
Glad it works.
Feel free to tell us for any further problem.

Hi, Zizzi
Thanks for your kind words. We are glad that our guide helps.

"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???
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.. :/
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.
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?
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...
Thank you for the information and the provided links, I could finally read the book I purchased on my kindle.
Thanks for sharing!
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?

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
