2 Ways to Read ACSM on iPad, Read ACSM with iBooks

Posted by on .

When we download ebooks from online store, it's common for us to find that many books are ACSM files. You may have read these files on your computer previously. But now, you just got a new iPad and you can carry it everywhere. So reading your books with iPad is a wise choice. You tried to transfer these books to your iPad and open them, but finally failed. Now you wonder the reason and want to know how to read ACSM on iPad, but still cannot find a satisfactory answer, right? Don't worry, this guide can tell you the reasons and 2 useful ways to help you solve this vexting problem.

Read ACSM with iBooks After Removing DRM

In fact, there are 2 reasons that we cannot directly open ACSM files on iPad. Firstly, an ACSM file is not a real book file at all. It's just a download link for us to get the complete EPUB or PDF books. Besides, ACSM files are usually protected by Adobe DRM, which is not supported by iPad.

There is already a good app on iPad--iBooks. If you want to read the ascm files with iBooks, then this part will be very helpful for you. To read ACSM files with iBooks, we just need to remove the DRM, transfer the DRM-free books to iPad and then enjoy them via iBooks.

Tools you will need:

1. Adobe Digital Editions for PC/Mac

To get the actual book files, we need ADE on our computer to convert the acsm files to EPUB/PDF books.

2. Epubor Ultimate

To remove DRM from ACSM files, we need a DRM removal tool to help us. Here I recommend you a powerful software--Epubor Ultimate--which can help you remove the DRM with ease.

1 Remove DRM from ACSM Files

Launch Epubor Ultimate. Then it will automatically detect and upload your books. As you can see, all the books here are listed under the "Adobe" tab on the left side. Just drag and drop them to the right area. Then all the books will be decrypted immediatly.

2 Transfer the Decrypted Books to iPad

Once all the DRM-protected books have been decrypted successfully, you can just click the blue output folder icon at the bottom-right or "vDecrypted" at the end of each title to find your DRM-free books. Then you can transfer them to your iPad and read these books freely with iBooks. To learn more details, you can go through how to transfer books to iPad.

Read ACSM with a Third-Party Reading App

In order to read ACSM on iPad, we can still install a third-party reading app that support .acsm file, such as ADE and Bluefire reader. In this part, I will tell you the detailed information about how to do this.

1. Adobe Digital Editions App for iPad

First, please install ADE app on your iPad. Just open your App Store on iPad, input "ADE" in the search pane find ADE for iPad to download and install it.

Once you have installed ADE on your iPad successfully, you can transfer your downloaded ACSM files to your iPad.

Method 1 Use iTunes to Transfer the files

Connect your iPad to the computer with USB cable, open iTunes. Then tap the device icon on the left side of iTunes, select the "Apps" option and find "File Sharing" section. Click on ADE under Apps, tap the "Add" button to load downloaded ACSM files on your computer, and then just click "Sync" to transfer these ACSM files to your iPad.

Eject your iPad, open ADE app on your iPad. The "Library" will display all your transferred ACSM files. When you click them, the ADE will ask you to authorize your device. You just need to input your Adobe account information which is associated with your downloaded books, then tap "Authorize" to authorize your iPad.

After the iPad is authorized successfully, ADE will download the full content books for you. When downloading is finished, you can read ACSM files on iPad freely with ADE reader.

If you have opened ACSM files on your computer with ADE, it also downloaded the complete EPUB/PDF files for you. You can just transfer these downloaded EPUB/PDF books to ADE on your iPad. After you have authorized your iPad, you can directly read them on iPad with no need to download them again.

Method 2 Download the ACSM files on iPad directly

You can also directly download ACSM file from your iPad browser, then just select the ACSM, choose ADE to download EPUB files and read them.

In fact, I don't like ADE app for iPad very much, because even if I have authorized my iPad, it cannot sync the books which are already existed on my computer ADE. What's more, it cannot display the covers of my books very well.

2. Bluefire Reader for iPad

Bluefire Reader for iPad is a reading app which allows you to read eBooks in PDF and EPUB formats. The more important point is that it supports Adobe DRM, which means you can also read DRM-protected .ACSM eBooks on iPad with it.

Please download and install Bluefire on iPad at first. Then downloaded the ACSM files to your computer. Next please open ACSM files on computer with ADE to get the real EPUB/PDF books, and transfer the converted books to your iPad with iTunes. This is the same as the previous step for ADE app.

Once you open Bluefire Reader on iPad and tap the cover of the transferred books, it will ask you to authorize your device with your Adobe ID. Just enter your Adobe ID and password to authorize it. Then you can enjoy books with Bluefire Reader.

Note: No matter which app you pick up for reading ACSM files, please make sure it should be authorized with the same Adobe ID that is used for downloading the books.

Though Bluefire Reader can read ACSM files, sometimes there would apper some errors like "The request timed out" so that I cannot authorize my iPad successfully. This prevents me reading my acsm files.

Final Words

To tell the truth, I really don't like to install any other reading app on my iPad. Through comparison, the method of reading acsm with iBooks after removing the DRM is so easy, right? No need to authorize our device, no need to download any third-party app to iPad. I really hope tha it does work for you.
