How to Remove DRM from Your E-Books Using Calibre and DeDRM on Linux

If you're an avid reader who has accumulated a large collection of e-books, you may have encountered the frustration of dealing with Digital Rights Management (DRM) restrictions. Fortunately, there's a way to remove these restrictions using Calibre, a free and open-source e-book management software, along with the DeDRM plugin on Linux.

Before we dive into the process, it's essential to note that not all e-books are protected by DRM, and some may be more difficult to crack than others. However, for those who have purchased or received e-books with DRM restrictions, Calibre and DeDRM provide a reliable solution.

To begin, you'll need to install Calibre on your Linux system. You can do this by downloading the software from the official website and following the installation instructions specific to your distribution.

Once Calibre is installed, launch it and navigate to its preferences menu. From there, click on 'Plugins' and then select 'Get New Plugins.' Search for DeDRM and install it. This plugin will allow you to remove DRM restrictions from your e-books.

Next, connect your Kindle or other e-Reader device to your Linux system using a USB cable. If you're transferring books directly from your e-Reader, make sure it's properly connected and recognized by your computer.

In Calibre, navigate to the 'Add Books' menu and select 'Add books from directory.' Choose the folder where your Kindle or e-Reader stores its e-books. You can also add individual books by dragging and dropping them into Calibre's main window.

Once you've added your e-books, you'll notice that each book has several files associated with it. These files include metadata, such as title, author, and publisher information, as well as the actual book content.

To remove DRM from your e-books using DeDRM, follow these steps:

1. Head back to Calibre's preferences menu and navigate to 'Advanced' > 'Plugins.' Double-click on the line called 'File type plugins.'

2. In the new window, click the green plus button and select the 'DeDRM' plugin.

3. A small empty window will pop up, requiring your Kindle's serial number. Finding this number varies depending on the version of your e-Reader, so you may need to consult the manufacturer's instructions or search online for specific guidance.

Once you've entered the serial number, click 'Apply' in the top right corner of the Calibre window.

4. With DeDRM installed and configured, navigate back to Calibre's main window and select the e-book you want to remove DRM from.

5. Right-click on the book title and select 'DeDRM' > 'Remove DRM.' This process may take a few seconds or minutes, depending on the size of your e-book and the speed of your computer.

After removing DRM, you can enjoy your e-books in any format supported by Calibre, including EPUB, MOBI, and PDF. You can also convert them to other formats as needed using Calibre's built-in conversion tools.

In conclusion, removing DRM from your e-books using Calibre and DeDRM on Linux is a relatively straightforward process that requires some technical know-how but is well worth the effort. With this tutorial, you should be able to strip away restrictive DRM restrictions and enjoy your e-book collection without any limitations.
