How to remove DRM from epub

"Can I remove DRM from EPUB books I purchased and read them on other devices?"

This is one of the most common questions eBook users ask after buying titles from Kobo, Google Play, and similar platforms. Since DRM limits how and where you can open your files, many readers look for a practical way to remove DRM from EPUB. In this guide, I will cover the two best free EPUB DRM removal tools for EPUB files from multiple eBook platforms, along with a simple tutorial to help you get started.

Free EPUB DRM Removal Tool: Calibre

Calibre is one of the most commonly used tools for EPUB DRM removal, especially for users who need a free option or want to handle books from multiple platforms. However, Calibre itself cannot remove DRM from EPUB files, so you need to install additional plugins. Calibre DeDRM plugin can decrypt EPUB books downloaded through Adobe Digital Editions (ADE), such as books from Google Play Books. Obok plugin can remove DRM from .kepub or .epub files downloaded from Kobo.

As you can see, using Calibre to remove DRM from EPUB eBooks requires some basic computer knowledge. Otherwise, the setup process can feel confusing, especially for beginners. If most of your books come from the Kobo platform, we recommend trying the second EPUB DRM removal tool, BookFab Kobo Converter.

How to Remove DRM from EPUB with Calibre?

Step 1: Download and install the latest version of Calibre from the official site https://calibre-ebook.com/.

Step 2: Go to the DeDRM_tools GitHub Releases page and download the DeDRM_tools.zip. Extract it to a folder, and you will find two important plugin files: Obok_plugin.zip for Kobo-purchased EPUB or KEPUB books, and DeDRM_plugin.zip for Adobe DRM-protected EPUB books downloaded through ADE.

Step 3: Open Calibre and click "Preferences" > "Plugins > Load plugin from file". First install DeDRM_plugin.zip, then repeat to install Obok_plugin.zip if you want to remove EPUB DRM from Kobo books. Restart Calibre so both plugins become active.

Step 4: Once the plugins are installed, you can import your downloaded EPUB files into Calibre to remove DRM. The process varies depending on the ebook platform and DRM type.

📕For EPUB eBooks from Google Play, Nook, e-library, and other Adobe DRM-based platforms:

Step a. Authorize Adobe Digital Editions

Download and install Adobe Digital Editions from Adobe's website. Open ADE and go to "Help > Authorize Computer". Log in with the Adobe ID you used to purchase or access your books.

Step b. Download the Protected EPUB

Retailers using Adobe DRM usually provide an .acsm file instead of the actual EPUB. Open the .acsm file in Adobe Digital Editions, and ADE will download the DRM-protected EPUB or PDF. Once the book appears in your ADE library, right-click it and select Show in Explorer/Finder to locate the file on your computer.

Step c. Remove Adobe DRM from EPUB in Calibre

Open Calibre and click "Add books". Navigate to the folder where ADE placed the downloaded EPUB. Select that file to import it into Calibre. Then, the DeDRM plugin will automatically detect the Adobe DRM and remove it during import. After this, the book appears in your Calibre library as a DRM-free EPUB you can read, convert, or export.

NOTE: If your EPUB comes from Google Play Books, go to the Google Play Books website, open "My Books", click the menu next to the book you want, and choose "Export ACSM for EPUB/PDF" to download the .acsm file before opening it in ADE.  

📕For EPUB books from Kobo:

Kobo uses its own DRM variant, and the Obok plugin is designed to handle it. Once installed, Obok can pull your purchased Kobo ebooks from a desktop app or connected Kobo device and strip their DRM automatically.

Step a. Download Kobo Books to Your Computer

Install and open the Kobo Desktop App (Windows or macOS). Sign in with your Kobo account. Download the ebooks you want to process so they're stored on your computer. 

Step b. Romove Kobo DRM from EPUB

Close the Kobo Desktop App to ensure ebook files are not in use. Open Calibre and click "Add books". Select the Kobo files (.kEPUB or .EPUB) you just downloaded. The Obok plugin will detect the Kobo DRM, remove it, and add the decrypted book to your Calibre library. The resulting files will be standard DRM-free EPUBs ready for reading or converting.
