Calibre DRM Removal Plugins – Download and How to Use

Every hardcore eBooks fans must know the software Calibre. Basically, it’s a library manager and file converter, with hundreds of plugins it becomes even more powerful and omnipotent.

Among all the plugins, the Alf’s DRM Removal plugins are very important and useful, as it’s the only free and easy way to remove DRM. Besides the DRM Removal plugins, you have to run the scripts (which requires coding skills) or pay for some shareware.

By removing DRM, you truly own the eBook you bought. Or the books are sort of “rented” from those online retailers as they can easily wipe them from their cloud servers and then you are no longer own the book. Yes, you are still having the file on your computer, but if there is no such a book on the server, you won’t be able to pass the DRM validation and fail to open this book for reading.

Therefore, I’m not advocating for piracy here when I say we need to remove DRM. It’s just for safe back up. You also do not remove DRM from eBooks for piracy purpose.

OK let’s go. I am going to compile a step-by-step guide in this post, everyone can easily use Calibre DeDRM plugin by reading the following parts.
