What is ACSM?

You probably have downloaded ACSM eBooks from your public library to the computer or pulled down the books locally from the Adobe Digital Editions application, but found the books could not be opened in your preferred PDF or ePub reading apps. That’s because ACSM books can only be opened via Adobe Digital Editions(abbreviated ADE) and have DRM protection. The only way to break this is to convert ACSM to PDF/EPUB (and remove DRM).

ACSM file is an Adobe Content Server Message file which contains information about downloading a digital publication and is protected by the Adobe DRM.

An ACSM file is not the actual e-book, but a type of link or message between the user and the Adobe Content Server DRM software. When you open an ACSM file, the actual eBook is downloaded from a remote source via the Internet.

When you download the eBook (i.e. from your google play bookstore), you will get a file named “URL.ascm”. ACSM files have an average size of 1-5 KB.

Best Practices

Many booksellers use ACSM, but our products are not guaranteed to remove all ACSM copyright protection.

Of course we offer a trial, you can buy after the trial is successful.

Here’s a little tip. If your book can be opened with ADE version 2.0, then our software will be able to do the conversion successfully.
Anyway, the decision is yours.
