Convert ACSM to PDF and EPUB Free

Posted on Feb 3, 2015 | 5 comments

Sometimes when we download a purchased eBook, we only get an ACSM file. Then we get totally confused, having no idea how to read the ACSM file. In fact, ACSM file is sort of “key”, it is always only 2-3 KB. All the eBooks protected by Adobe Adept DRM are coming from ACSM. If you want a complete PDF or EPUB book, you need to convert from the ACSM file.

Download Adobe Digital Editions

At first download the Adobe Digital Editions (ADE) from Adobe Official site, or click the button below.

Then open Adobe Digital Editions and authorize it with your Adobe account.

• If this is the first time you installed ADE, please press “Ctrl + Shift + U” (Mac users press “Command + Shift + U”) to authorize the program;
• If you’ve installed ADE before and wanted to switch an 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 account

Add ACSM File into Adobe Digital Editions

Please do make sure the ACSM file is downloaded by your own account in online eBooks retailers, or you may fail to convert it to a complete EPUB or PDF book.

To take an example, I download an ACSM file from my Kobo library, as Kobo is adopting Adobe’s content server service (in other words, protected by Adobe DRM).

Now directly drag the .ACSM into Adobe Digital Editions, if you authorized with correct account, you will see the complete book is being downloaded.

Once the process is finished, the book will add into ADE’s library and open up itself.

Where to Find the Downloaded EPUB/PDF File

When the book is displayed in ADE library, a complete EPUB or PDF file is also saved in computer. Both Windows and Mac computer users can find the content folder in the path “Documents\My Digital Editions“, you can also right click on the book cover and choose “Show File in Explorer (Finder for Mac)“.
