Calibre is a totally free and open-source ebook tool. Did you know that there are many plugins you can install to Calibre to make full use of the best ebook management ebook software? When you find a Calibre plugin online, you may meet troubles when adding it to Calibre. So today I create this blog and would like to show you the step-by-step guide to adding a plugin to Calibre (Here I take the most popular DeDRM plugin as an example. It’s accessible to all the other plugins).

  1. Get your Calibre plugin prepared. (All the plugins are .zip files.)
  2. Download and install Calibre on your Windows, Mac, Linux computer.
  3. Run Calibre. Find “Preference” at the top menu bar and click it.

4. In the next pop-up window, hover your mouse to the end. Find “Plugins” under the “Advanced” option, and click it.

5. Then click “Load plugin from file”. Choose the plugin .zip file you’ve got.

6. Click “Yes” to proceed to install the plugin to Calibre.

7. Then a window will show that you’ve successfully installed the plugin under “XXX”.

8. For the DeDRM plugin, it’s installed under the “File type plugins”.

OK. That’s fine. These are the whole steps we should take to install a plugin to Calibre. There are many Calibre plugins available. You can just google “the best Calibre plugins”. Those plugins would make your Calibre more powerful and functional.

Note: Some plugins cannot be installed to Calibre 5.0 version or higher, including the DeDRM plugin, with a SyntaxError poping up.

To deal with this problem, you just need downgrade your Calibre to the older version V4.23 and then try to add the plugin once again.

Friendly Tips: If you think the DeDRM plugin re-installing is too comlicated, you can try the Ultimate ebook Converter. Besides Calibre, it is anoter well-known brand in converting ebooks. Compared with Calibre, it does not require you to install any plugins to remove ebook DRM.
