How to Open and Convert ACSM File to PDF? -

An .acsm format file refers to an Adobe Content Server file that it is not a real file but a link that allows you to download a purchased or rented eBook. This file takes data from the “Adobe Content Server” to activate and download the original content of the eBooks, usually in ePub or PDF format.

The ACSM file works as a connection between the Adobe Content server and the book-authorized Adobe Digital Editions ID, which means that if you use the same Adobe ID on different computers, you will be able to download and open the same DRM protected .acsm file with Adobe Digital Editions. This is one of the many reasons why so many eBook sellers use this eBook distribution method because they think it can provide perfect distribution of books on all devices.

The main reason eBook vendors use Adobe Content server to distribute their eBook content to their customers is that it can add DRM protection to eBooks. So if you have a ACSM you may be wondering how to open and view it. Below we will see all the possible solutions!

How to Remove DRM from ACSM Files

After converting the .acsm to pdf or epub, you can open and read them with ADE. But you can't open your downloaded PDF or EPUB with your favorite reader. This is because the pdf / epub files are protected by drm to prevent the free circulation of the book. To read DRM protected ACSM PDF or ACSM EPUB, you must first remove this protection.
