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 and read them on common reader devices and software. For details about converting ACSM to EPUB, 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 3 steps.

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.

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.

authorize adobe ID

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

Step3: Open .ACSM 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".

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 work 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 all the job converting acsm to PDF 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 Adobe PDF ePub DRM Removal which makes it possible to convert ACSM to Kindle (azw, mobi) and convert acsm to iPad.

Windows Version Download Mac Version Download

All you have to do left is just to run the soft and click the "Remove DRM" because it can grab your PDF eBooks automatically.

This is a scam.

You will die Adobe.

How dare you lock our libraries up to line your pockets.  FUCK ACSM DRM EPUB MOBI SHIT.

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.

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.

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.

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.

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.

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.

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.

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.
