Why we have to convert acsm to kindle

In my previous articles I have written what the acsm file is. When you borrow or purchase ebook from online store, public library, what you are really downloading is an acsm file. It's not an actual ebook, but only a link to your book, allows a program to download the book. In common acsm file always comes with DRM.drm acsm

ACSM is the short name of Adobe Content Server Manager, so you know that acsm is produced by Adobe. In fact, Adobe Digital Editions is the program that has the rights to open acsm file. When ADE see the acsm file, it will automatically download acsm to the PDF or EPUB format. But ADE can be only installed on computer, pc or mac, but not kindle. So here comes the reason 1: acsm file can be opened only on computer with ADE.

Additionally, let's talk about kindle devices' shortcoming. We know reading kindle books on Kindle is enjoyable, however, this also brings us problem, we can't read any ebooks if they are not kindle format. But our acsm file can only be opened to epub or pdf. In a word, the reason 2 is that Kindle devices don't support acsm format.

So we must convert acsm file to kindle format. As mobi is the native kindle format, so I recommend you convert acsm to mobi.

word of warning: it works, but unless you pay $25 then it will only give you a converted preview of the book (20% of it) and leave out the rest. wow what a massive waste of time, only to get stuck here.
