Are you a book lover? If you always buy e-books online, you will know that the books we download or purchased from the Internet are sometimes in ACSM format. But it can't be opened directly because it is only a link. If you want to read your ebooks, you need to convert the ACSM to ePUB format. Besides, you need to remove DRM in ebooks. Many people still have trouble with these two questions. Well, don't worry, keep reading this passage. You will learn a complete and thorough guide on how to convert ASCM to ePUB and how to remove DRM.

What Are ACSM, EPUB, and DRM

Before getting to the point, let's first learn a few basic concepts in this article. So what are ASCM, EPUB, and DRM? It will be puzzling to read the article if you don't understand these three words.

ACSM is an abbreviation for Adobe Content Server Message. It is not a real file that we can open or read directly. Actually, it is a download link distributed by Adobe Content Service, which is used to activate and download Adobe DRM-protected content. 

ePUB is an abbreviation for Electronic Publication, an e-book format that uses ".epub" file extension. The EPUB file is compatible with most devices like kindles, tablets, smartphones, etc. So this file format is widely used just like PDF.

So if you want to open and read the books you bought or subscribed to, you must change the ASCM format into another readable format like EPUB.

DRM is an abbreviation for Digital Right Management, which aims at protecting files copyrighted works from being wrongly used, modified, or distributed. 

The books that we converted from ACSM usually come with DRM. So if you want to edit or use the content, you need to remove it in advance.
