Free EPUB DRM Removal

EPUB is the most widely supported vendor-independent XML-based e-book format; that is, it is supported by the largest number of hardware readers. The majority of mainstream eBook stores, like Google Play Book, Kobo, Barnes & Noble's Nook, etc, has adopted ePub format.

The open-source EPUB e-book format is great for sharing books between different readers and making life easier on readers generally--but epub books purchased from eBook stores usually comes with DRM(Digital Right Management) which locks your purchased book within its app and reader devices.

You will get a acsm link instead of ePub file. So next you need to open the acsm file with Adobe Digital Edition to download the ePub file to your computer. Then the downloaded epub files will be displayed under Adobe column in the left sidebar of Epubor Ultimate. If you are not sure how to convert acsm file to EPUB files, you can read this guide about how to download Google Play Books to your computer.

Tool 2: Calibre

Calibre is open source software while DRM by its very nature is closed. Though Calibre doesn't support opening or viewing DRM files, it can also be used as DRM removal if De-DRM Plugins has been loaded to Calibre. But if you don't know much with computer, Calibre is going to drive you crazy.

Step 1download Calibre to your computer and launch it.

Step 2download De-DRM Plugin to your computer.

Step 3load De-DRM Plugin to Calibre.

Open calibre's Preferences dialog. Click on the Plugins button. Next, click on the button, Load plugin from file. Navigate to the unzipped DeDRM_tools folder and, in the folder DeDRM_calibre_plugin, find the file DeDRM_plugin.zip. Click to select the file and select Open. Click Yes in the "Are you sure?" dialog box. Click the OK button in the "Success" dialog box.

Step 4add DRM-ed epub book to Calibre


1. These tools do not work with kepubs downloaded using Kobo's desktop app. So you need to download the epub file on Kobo website. When you click the Download, you will get a .acsm file instead of a epub file. Then you need to open the acsm file with Adobe Digital Edition to get the epub book. At last, you just need to add the epub file to Calibre to remove it‘s DRM.

2. You must add some key information if Barnes & Noble ePubs were downloaded using Nook for PC instead of NOOK Study

Let's say if you download the Nook book via Nook for PC, then you have to add needed key information for other books, highlight the plugin (DeDRM under the File type plugins category) and click the Customize Plugin button.

Select Barnes and Noble ebooks.

Then Calibre can remove DRM from your Nook books.

UPDATE: Calibre can no longer remove Nook DRM because Nook has changed their DRM scheme.

3. For Google Play epub files, you need to download the epub on Google Play Book website. Then you will get a .acsm file. Next open the acsm file with Adobe Digital Edition to get the epub file. Last add the epub file to Calibre to remove DRM.

Comparing to Epubor Ultimate, it's really complicated and annoying to use Calibre to remove DRM from ePub files. To be honest, the DeDRM plugins has too many limitation and rules. It really drives me crazy to decrypt DRMed epub files with Calibre at one point. And I'd rather purchased a licensed Epubor Ultimate to help me unlock my epub files fastly and conveniently.
