About ACSM files
An .ACSM file is an Adobe Content Server Message. It is not an actual eBook. Instead, it is an XML token that authorizes the download of a DRM-protected EPUB or PDF file from Adobe's servers. To open it, you must use Adobe Digital Editions. You can read more about Adobe's DRM on Wikipedia. The .ACSM format is highly frustrating for users. People buy an eBook, expect an EPUB, but receive a 2KB file that cannot be read on standard devices like a Kindle. It is heavily restricted by proprietary Digital Rights Management (DRM). It requires creating an Adobe ID and installing specialized software just to retrieve the actual book. Furthermore, the token often expires after a short period. You cannot directly convert an .ACSM file without first downloading the linked eBook. Once you fetch the actual EPUB or PDF using Adobe Digital Editions, you may wish to convert it to bypass device restrictions. For reading on a Kindle, convert your downloaded file to AZW3 or MOBI. For archiving, use .PDF/A.
Convert.Guru analyzes your ACSM file, detects the exact format, and lets you read the text inside.
If you want to convert ACSM file to PDF, EPUB, MOBI, AZW3, AZW, KFX, PRC, LIT, OPF, CBZ, CBR or CB7, you can use Adobe Digital Editions or similar software from the "Ebook Download DRM Token" category. In the File menu, look for Save As… or Export….

The ACSM Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our ACSM converter.
