It is just a link to your eBook that allows a program like Digital Editions to download the actual book, The idea that you could convert an .acsm file to a .pdf file is based on the assumption that the .acsm file contains all the text of a book, and that it’s just in the wrong format.

EPUB is a free and open e-book standard by the International Digital Publishing Forum (IDPF). Files have the extension .epub.

An EPUB file can optionally contain DRM as an additional layer, but it is not required by the specifications. In addition, the specification does not name any particular DRM system to use, so publishers can choose a DRM scheme to their liking. However, future versions of EPUB (specifically OCF) may specify a format for DRM.

There are a variety of options for publishers who want to create digital editions.
