How to Read ACSM on Kindle

Posted by on .

If you download an eBook from an online ebook store, and you want to read the book on your Kindle eReader, the resolution is to convert acsm to Kindle. You would ask why and how to do it. Don't worry. You will get the comprehensive answer in this article.

To read acsm on a Kindle, follow these 4 steps.

Step 1 Using Adobe Digital Editions to open your ACSM files.

Step 2 Once opened, the ACSM will be saved as ePub or PDF.

Step 3 Remove DRM from the ACSM.

Step 4 Convert ACSM to Kindle supported format.

The following 4 parts will address all your questions.

Part 1: What's an ACSM File

After you purchase an eBook online from the public library or a private bookseller, you can download it to have a look.

what the acsm file is However, typically the downloaded file uses an .acsm suffix. In other words, the majority of the books you got from online stores are in ACSM format.

You may be confused about this file type since the acsm is not your actual eBook. It's actually a download link to your eBook.

Part 2: How to Open with ACSM File

ACSM stands for Adobe Content Server Manager. This name suggests that Adobe manages the downloading of the ACSM file.

I would recommend using Adobe program Adobe Digital Editions to open your acsm file. It's also the best acsm ebook reader.

install ADE to open acsm file Step 1, create an Adobe account and authorize it.

Step 2, run ADE program and open acsm with it.

Double click acsm file and ADE will automatically start downloading your book as PDF or ePub, which is the actual eBook you purchased.

Step 3, read acsm file in ADE. (how to read books on ADE)


ACSM doesn't allow us to reproduce and transfer, and it can only be used on the computer where you have downloaded the books. So I can't stress this enough: Before you buy Adobe ebooks, whether PDF or ePub, please install the Adobe Digital Editions. Only by using this software you can open the acsm file and read it on your computer.

The details are referred to at these links:

Part 3: How to Add ACSM File to Kindle

As previously explained the ACSM file can only be opened with ADE on your PC. If you try to open this file with any application such as Kindle for PC rather than ADE, it will issue an error message.

This is because once we download an acsm file and open it with ADE, the acsm file will be associated to ADE (Adobe Adept DRM). There is no compatibility with Kindle or iPad. Even worse, if we want to read acsm on Kindle, there is another problem we have to solve besides the DRM protection. It's the format limitation. This is because the Kindle only supports its own format such as AZW3, AZW, MOBI, PRC, TPZ but not the common ePub or PDF.

So here you may find the key to resolve your problem to read acsm on Kindle: Remove Adobe DRM and convert ACSM to Kindle format.

When I attempt to ope the 'ascm' file in ADE, an error window pops up stating:
                            "ERROR!CHECK ACTIVATION".
What does that mean and what should I do?
11/17/2014 19:46:00
1, Check if you ADE has been authorized.
2, Check if you are authorizing the correct account which is the owner of the book

I bought in Google Play.

OK the Google Play books can be decrypted correctly. The most possible reason is the Adobe ID database is messed up.

The most solid solution is find a new computer which hasn't installed Adobe Digital Editions yet.

Or you can try to reinstall ADE or use some apps like CCleaner to clean the remaining information of ADE.

GREAT FORMATTING! The best thing's that the formatting in the resulting MOBI file is perfect. It's exactly like the original EPUB file just compatible with Kindle. Thank you very much.
06/8/2015 21:10:22
Wow!  Thanks.  Worked great.  Excellent instructions.  Only one thing you left out - Ultimate Converter costs $25, although you can get a free trial to give it a try, which I did.  Not sure how long the trial lasts.

Good day, I am just wondering the converted MOBI format will work the same as a native MOBI file? Would their properties be the same? For instance, can I still highlight notes and save them for future access?
09/1/2015 02:51:49


Yes, converted Mobi format will keep the original content without quality losing.

Maybe you can have a try to see, converted files will not replace your original Mobi books.

Hello, I'm trying to convert an Adobe e-book (acsm file) to Kindle (Kindle for Mac). I've selected Kindle as my output format and the "E-book Converting" message has been up for several minutes now, with the blue loading-bar full from the start. Does that mean it's still working? If so, how long might a 118mb file take?

Also, am I doing this wrong/ is there a better way to do this?

Thanks, Ryan

01/4/2016 23:19:54


It seems your file is a little bit large, it may take a while for converting.

As long as the conversion has been finished, the output folder will pop up automatically.


01/5/2016 00:52:04
Thanks for getting back to me, I will be more patient when I try it again. I see there's no Kindle for Mac Output Format, but there is a Kindle for PC output format. If I want to convert the Adobe Digital Editions file to Kindle for Mac, which Output Format do I select?
01/5/2016 23:03:39


You can just select Mobi as output format.

01/29/2016 14:46:36

I have successfully converted the ACSM file to MOBI format!
Now, how do I open the MOBI file with the Kindle for Mac app?


01/31/2016 23:59:47


Yes, you can open it via Kindle for Mac app. If you have Kindle eReader, you can also transfer converted mobi file to it.

Thank  you !

I want to use Kindle for Mac to read my book that is currently on Adobe Digital editions (ADE). Based on this page, my plan was to convert the ACSM file to a MOBI file so I can read the book on Kindle for Mac.

But, I am confused because: This page mentioned that once ADE opens the ACSM file, it becomes a PDF file. The page also says that you must first open the ACSM file in ADE, and then convert the ACSM file to a MOBI file using Ultimate software. BUT, if I have opened the ACSM with ADE, the ACSM file is now a PDF! That is, when I look in the right side area of the Ultimate software under ADE, my book is a PDF!

Am I supposed to convert this PDF to a MOBI file? - This method doesn't allow for the removing of the DRM from the ACSM step above; when I select this PDF to convert to MOBI using the software, and then open it in the Kindle for Mac reader, It becomes a messed-up mix of letters and partial pages; so I don't think this is the way. If it is, what am I doing wrong?

If I am supposed to be selecting an ACSM file from the right side of the Ultimate software under the ADE tab, how do I make it appear there?

Thank you, Sean

02/1/2016 00:07:43


Yes, the correct step is: open acsm file via ADE, download complete PDF, launch our Ultimate, drag PDF file to it, the DRM will be removed automatically. Then convert PDF to Mobi.

You can email to support@epubor.com for technical support.

Thank you !

07/18/2016 18:42:34
Um. My Kindle Fire doesn't have ADE in the app store.
08/2/2016 20:23:05
you have to download it from google playstore which you can download to your kindle
08/4/2016 02:56:48

You can only download ADE to your computer(PC or Mac), then make sure you can read your ACSM with ADE.

Once your ACSM saved as ePub or PDF, using the tool to help you convert your book to Mobi.

Then, transfer Mobi to your Kindle Fire.

Thanks for the guide!

03/28/2017 17:33:15
Once converting finished, the output folder will pop up automatically, you can also click on "succeeded" to find them.

Hi everyone;

I have a question. I have an ebook i am downloading it and I receive URLLink.acsm it is right but when I download same folder with safari on mac this folder downloading like URLLink.acsm.xml . How can I fix it in my codes. I am coding with c#.
This problem is because of safari. Safari decides extension of file automatically and my folder's content is xml but it is a link and after download must be .acsm extensson not acsm.xml
How can I prevent safari to not check folder's contain.

03/31/2017 09:42:59
Thanks a lot for the tutorial. I've only a question: Although I can read the book without any problem in my Kindle Paperwhite, I cannot highlight, change the font, or look up any word in the dictionary. Is there any way to do it?
07/19/2017 03:37:07
It doesn't convert the whole book. Not even half.
07/20/2017 09:56:05
The trial version only can convert 20% of each book.
11/5/2017 21:55:38
THank you so much!!
09/8/2018 11:12:42
Nice work.
09/8/2018 11:26:01
It works like a charm. Now I can transfer my acsm file to my kindle oasis.
11/28/2018 08:13:03
nice !!
thank you!!
04/22/2019 12:19:44
I'd love to see these instructions written in English.
12/25/2019 21:59:16
Please mention that you have to buy a program license. It is dishonest to describe the tutorial without mentioning.
12/27/2019 09:19:23
Thank you for leaving the comments. We don't mention Epubor Ultimate is a free software.
02/16/2020 21:36:53
Requires buying  £25 license to remove DRM from a book that costs £2. Pointless waste of my time.
12/8/2020 15:50:57
