How to Convert ACSM to PDF Free

Posted by on .

When we purchase eBooks from public library, you may find that the majority of these books are the ACSM format but not the common EPUB or PDF format.

What is an ACSM file? As the image below shows, an .acsm file is not an actual eBook but just a file download link.

In my opinion, converting ACSM to common EPUB or PDF is the best way if we want to open .acsm file and read them on common reader devices and software. For details about converting .acsm to .epub format, I highly recommend you have a look at the article convert acsm to epub and remove DRM.

Today what I'm about to deal with in this article is the way how to convert ACSM to PDF. Just need 3 steps.

convert acsm to pdf

To convert .acsm to PDF, you just need these simple steps:

Please note that the PDF generated from .acsm is DRM protected, if you want to convert the format, back up the file, or want to read it freely, you need to remove the DRM. This article also covers this part.

Below is the detailed guide.

Step1: Install Adobe Digital Editions

ACSM is designed by Adobe which helps you manage, read or transfer your ebooks to another e-reader. Furthermore, only Adobe Digital Editions can open acsm file.So firstly please download and install it.

install Adobe Ditital Editions to convert acsm to pdf

Adobe Digital Editions for Windows download: ADE for Win (8.13MB)

Adobe Digital Editions for Mac download: ADE for Mac (23.2MB)

If you have already installed you can skip to the next step.

Step2: Authorize Adobe ID

If this is the first time using ADE, you will see a dialogue box. Then you need to input your Adobe ID to authorize the current computer. Of course you can also creat an Adobe account to register if you don't have an Adobe ID yet.

authorize adobe ID

Then enter your Adobe ID and password, click the "Authorize" button to activate it.

Step3: Open .acsm File and Download the PDF books

Now find the .acsm files you downloaded in the computer, then double click them, they will be opened by Adobe Digital Editions as default. If they can not be opened normally, you can click the right mouse, select Open with—Adobe Digital Editions.

open converted acsm file with ade

When Adobe Digital Editions runs, it will automatically download the PDF books, which are the actual eBooks. And if you have already downloaded the .acsm files as ePub format, you can also try to convert ePub to PDF.

As soon as the downloading part is completed, you would see all your PDF books. Choose one book in the main window, click the right button and select "Item Info" , a new dialog box will pop up. It shows the location of the downloaded ebooks.

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

For Mac: Users\ Your computer name\ Digital Editions ...

Until this step converting ACSM to PDF format has been finished with the free acsm to pdf converter. Congratulations!


You can read your converted PDF books on Adobe supported devices, such as Kobo Aura, Sony eReader, etc. Just copy them with the USB cable. But there is an important thing you should remember that it would be better to make your eReaders be authorized with the same Adobe account (the same e-mail address).

In addition, I have to tell you a truth that you can't read these converted pdf books on Apple devices (iPad mini Retina, iPod, iPhone) and Kindle devices (Kindle Paperwhite, Kindle Fire HDX) because these PDF books are protected by Adobe DRM. To meet your demand perfectly, I recommend you the best software Epubor Ultimate which makes it possible to convert ACSM to Kindle supported formats(azw, mobi) or convert acsm to Apple device supported formats(iBooks Author).


All you have to do is just to run Epubor Ultimate and it can detect your PDF eBooks automatically. Then you drag the books you want to read on other devices to the right blank space. Voila! All ebooks will be decrypted at once and you can convert them to any formats you want.

lets start the revolution, baby.
02/18/2014 02:02:16
Thankyou! This is a lifesaver. I thought I was stuck with the awful Booktopia app!
06/10/2014 13:50:12
Totally works and yes really annoying I ***** paid money for this book and you companies make me first convert it to another format then remove DRM.
It's like with the games and DVDs - The honest buyers are just left standing.
06/12/2014 12:28:56
I had a book of Windows 2012 could not open with this contribution I can make and if formatting my computer I can open another user solamante my Adobe and my ASCM file. Thank you helped me.
06/19/2014 15:24:35
might want to put this information that this won't work for Apple devices AT THE TOP of the page, before people follow all the steps...
08/1/2014 01:55:43
Thanks for your good suggestion. After you convert acsm to pdf, you can put it to Apple devices, but if the acsm is from Apple store, with this method we can't convert acsm to pdf, for the Apple DRM problem.

I have been trying to convert ascm to epub till 10 hours.

Your method converted my ascm to epub.

Thank you so so much. I'd like to pay for it. You know my email please email me your paypal email.

08/1/2014 01:59:10

Thanks for your comments.

You can go to product page to buy it.

07/28/2014 14:45:44
welp. I downloaded ADE and when i double click me 'ebook' it still comes up in Adobe Reader so I tried left clicking and going "open with" but it still hasnt got ADE in there even though it is fully downloaded. Fun :(
08/10/2014 20:15:49

You have two options to solve this problem.

1. Click "Open With", if you can't see ADE, then browse the program to open it.

2. Open ADE at first, then drag the book into ADE's window.

08/7/2014 23:35:24
Worked perfectly!
10/30/2014 00:18:55
Many thanks for this. greatly appreciate your help

I have already one ebook.if i open adobe digital editions the book is opening up.i have sign up for adobe account. how can i authorize my own current computer so that the acsm file can be converted into pdf
11/27/2014 18:27:34

If you aren't prompted to authorize ADE the first time you open it, you can go to Help > Authorize Computer to start the process manually.

Then just drag the .acsm file into ADE.

I paid for the book on Google Books. I've clicked on "download pdf". The file downloaded was in .acsm format but I need to read it on pdf cause I don't have any ebook reader. Your method only allowed ADE to open and read my book but doesn't change it into pdf....nevermind. I've noticed where your information was unclear. I'll give some feedback.

First of all, this part written where it is, is confusing, "And if you have already downloaded the ACSM files as ePub format, you can also try to convert ePub to PDF."

-if the file is in .acsm how do we know whether it's in ePub format? And you say this after you said the .pdf has been downloaded. So I thought, "if the pdf is already there, why should I bother with the ePub format? What should I be doing with this info? How do I know if I've downloaded it in ePub format? It only said .acsm"

And for this part, "Choose one book in the main window, click the right button and select "Item Info"..." it would greatly help if you have visual aide. Make sure there's a book there on the ADE bookshelves.

And most importantly, for the purpose of this article, you need to CLEARLY mention that you don't have to have a program that'll CONVERT the .acsm into .pdf, instead ADE will HELP you DOWNLOAD to .pdf and in order to find out where it is automatically stored, you can continue with your next instructions.

04/3/2015 20:30:15
You are correct! .acsm is just the key for downloading ebook file.
But a few people can't understand what's .acsm, they need ebook files, then want to "convert .acsm to epub/pdf".
04/17/2015 10:40:38

I've downloaded ADE and authorized my computer. When I use File > Add to Library and select the .acsm file, I get an error message:

Error Getting Licence. License Server Communications Problem:

What did I do wrong, or how to get the file to convert to .pdf?

You have to ask Google to reset this count in order to download again your book.

1- Visit this link

2- Click in CONTACT US (upper right corner)

3- Explain the problem

This software worked perfectly on my ACSM files. The process is very simply to follow. This useful little thing desires a good review.

Can you tell me more details about your problem? To open ACSM file. please install ADE on your computer and authorize it with  your Adobe ID.

Make sure you authorize with the same email address which is used to purchase your books.

10/2/2015 07:24:21
Hi, I tried what you just outlined above but upon installing ADE and opening the acsm file, the ebook opened. I looked for the ebook file following your step but ADE didn't save it as epub but instead as .pdf file that when clicked, will just route you to the ADE browser page, or just open an acrobat reader. Any help?
10/7/2015 23:34:42


You can use ADE to read these PDF files. If you want to read them on other platform, you may need to remove DRM first.


12/21/2015 00:47:26
You can right-click this .pdf file, then "open with", next choose the ADE program to open your pdf file please.
11/22/2015 20:23:17

Thanks for the article. Shame about the whole Adobe thing.

Can't believe I'm supposed to download some Adobe app to get a book I paid for. If I'd known this I would not have supported Google Play and I never will again. Every time I install an Adobe product I have to fight tooth and nail to keep their fucking bloatware off my machine. Obnoxious, invasive bullshit. Can hardly believe a software giant like Adobe is so intent to grasp at every penny that they would engage in an embarrassing practice like that. Any have you ever read their TOS? Check out flash player sometime. If anyone can give Google a run for their money on being invasive, it's those guys.

Bite me, Adobe and Google.

12/26/2015 17:04:07

It won't work for 128-bit RC4 encryption i tried and if any one can help me i'll pay for it

12/27/2015 20:41:52


Can you tell me more details about your problem?

12/31/2015 15:06:34

I'm impressed. I have to admit I was a little skeptical at first, but this successfully decrypted my ACSM from Google Play.

Thank you so much!

01/21/2016 01:57:40
Worked just great!! Thank you soo much!
01/31/2016 06:10:23
Thank you this worked perfectly. I was very frustrated when I bought a teaching resource book from google and couldn't even print off the worksheets. I wasted a lot of time trying to work it out until I found this method. Very happy now. :-)  
02/9/2016 18:09:52
Does it contain malware? I don't want my PC to get infected.
02/15/2016 01:06:02


The software doesn't contains any malware. It is 100% clean and safe.

03/4/2016 05:23:28

08/4/2016 02:39:09

Firstly make sure you have finished the downloading of your ACSM file.

Then, drag the file to ADE, soon ADE will download the file and save it as ePub or PDF.

02/23/2017 13:20:55

I did everything you said, but the PDF file I found is BLANK! I did with several books and still happening..

please help!!

Hello, if possible send your screenshot image to epubor support staff ([email protected]) so that you can get the problem well resolved.

I have been using Kobo Ereaders since they first came into existence. I tried many differing softwares, but the only one I stick with is Epubor Ultimate. This is the best and easiest book conversion tool there is. The few times I have required help, Ada and the team of agents have been great.If I had a problem converting a book, all I had to do was send them the book file and they even did it for me. Superb customer service and care. I wish all companies were like this one. Thank you all at Epubor!

Hi, I understand your instructions clearly. The only problem is that my ADE 3.0 will not open. I was using 4.? but downgraded thinking it might help. Nope. When I click on ADE it will open on my desktop (Windows 10-64Bit)and then show "Loading Library..." and the dots will blink over and over.

Have you any suggestions that might help? I already tried the 2x4 & a good swift kick but neither have helped. Thank you.

12/11/2017 14:45:44
For this issue, please contact the customer service via tickets:http://ticket.epubor.com/
Please describe your problem clearly and they will give you the instruction to solve your problem.
