How to Convert Adobe ACSM to PDF Free

Posted by on .

When acquiring eBooks from a public library, it's common to encounter the ACSM format, rather than the more prevalent EPUB or PDF formats.

What exactly is an ACSM file? As depicted in the image below, an .acsm file serves as a download link and not an actual eBook.

In my opinion, the best way to open .acsm files and read them on common reader devices and software is by converting them to the common EPUB or PDF formats. For details on converting .acsm to .epub format, I highly recommend you take a look at the article Convert ACSM to EPUB and Remove DRM.

In this article, I will be addressing the process of converting ACSM to PDF in just 3 steps.

convert acsm to pdf

To convert .acsm to PDF, you just need three 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.

Step 1. 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 Digital 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.

Step 2. 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 create 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.

Frequently Asked Questions
Q: "Incorrect login ID or password for the selected eBook vendor. Please try again". Unable to authorize ADE with google vendor id?

A: Though Google docs told us that we can authorized ADE with google id, but in fact most of us will fail to finish the authorization. This makes us frustrated. If you met the same problem, the correct solution is to obtain an Adobe ID (use the same email address as your google id).

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.

When Adobe Digital Editions runs, it will automatically download the acsm to pdf or epub files, which are the actual eBooks. And if you hapeen to download 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 ...

That's all. Now you've successfully transformed your acsm files into PDF format with Adobe Digital Editions. 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 keep in mind that it would be better to make your eReaders be authorized with the same Adobe account (the same e-mail address).

Convert Adobe-only PDF to regular PDF no DRM

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.

Is it possible to convert ACSM files to PDF format online?

There are some acsm converters such as AnyConv which claims that they can help convert adobe digital editions books to pdf online. But here I would say that since acsm files are bundled with your adobe id, you are not allowed to convert acsm to pdf online without the authorization from adobe digital editions unless you telling the third-party website your adobe account information. That's not safe. So the online ACSM to PDF converter is not recommended here.

In contrast, I highly recommend you open your acsm files via the Adobe Digital Editions on your local computer, and then convert the drm protected files to normal ePub or PDF format to backup them with Epubor Ultimate.

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

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.

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!

01/31/2016 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. :-)

Hello, if possible send your screenshot image to epubor support staff (support@epubor.com) 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!
