DRM (Digital Rights Management) is a usually polarizing topic. Some call it a necessary evil because it protects the rights of the copyright holder, while others term it a big hassle for the consumer who doesn’t deserve that when he has already paid for the product. The downside of DRM hit me when I bought Kobo, a digital e-ink reader, few days back.

Calibre is open-source software and costs nothing, although if you find it useful you might throw developer Kovid Goyal a few dollars. Calibre is available for Windows, Mac, and Linux. Download Apprentice Alf's DRM removal tools for ebooks. This comes as a.zip archive, so open it up and put the 'DeDRMcalibreplugin' folder where you can find it. The DeDRM calibre plugin only imports the HTMLZ versions of the Topaz ebook. The html version can be manually cleaned up and spell checked and then converted using Sigil/calibre to epubs, mobi ebooks, and etc.

As you might know, ebooks that are bought from Kindle store can only be read on Kindle apps and devices. As a consumer, when I have already purchased the digital media why should I be stopped from reading it just because I didn’t buy a Kindle and a Kobo instead? You with me on this? Then here’s how you can remove DRM from ebooks you have purchased on the Kindle store.

Note: This guide is for personal use only. Do not circulate decrypted eBooks over the internet or using any other media. According to the DMCA (Digital Millennium Copyright Act) it’s a punishable offence. We at Guiding Tech cannot be held responsible for any misuse.

Removing DRM from Kindle Books

Step 1: Download and install Kindle for PC and Calibre for Windows on your computer. Once you have installed these tools, launch the Kindle app for Windows and download the books you would like to remove the DRM from to your hard disk. To download the book, log in to your Kindle account, right-click on the book you would like to download from your library and select the option Download. Once you have done that, you can close the app.

Step 2: Download Alf’s DRM removal tools and extract the content to a folder in your computer. While downloading the file, the host would ask you if you would like to use the web service download manager. Don’t forget to uncheck the option before you start downloading. Just to be extra cautious, make sure you download a Zip and not an Exe file.

Step 3: Now run the Calibre tool on your computer. In you are using the tool for the first time, you might be asked to configure it. Just select the default options and complete the wizard. Once you are on the main screen, click on the Preferences button and select Plug-ins from the window that opens up.

Step 4: In the Plug-ins windows click on the option Load plug-in from a file located at the bottom of the page and import all the zip files contained in Alf’s DRM removal tools/Calibre_Plugins folder. Once you have added all the plugins, restart Calibre.

Step 5: Now the easiest way to remove DRM from a book is to import the file to Calibre. To do so, click on the Add books button on Calibre and import the book from Kindle directory which is %userprofile%documentsMy Kindle Content. Make sure you import the .awz file type to the library.

Step 6: As soon as the file is added to Calibre it’s decrypted and the DRM is removed. You can now convert the file to various formats using the right-click context menu and read it on any device capable of reading an eBook. We have covered a complete guide on how to convert ebooks formats using Calibre that you might find useful.

Conclusion

So that was how you can remove DRM for ebooks purchased on Kindle and read it on any device. This should come in handy for people who love shopping eBooks on the Kindle store but want to read it on an eBook reader other than Kindle.

About calibre
Calibre is a free, open source, ebook management and conversion utility created and maintained by Kovid Goyal. It is available for Windows, Mac OS X and Linux.
Calibre cannot, on its own, remove DRM from ebooks. However, it is possible to added third-party software (‘plugins’) to enhance calibre.
To be able to use the DeDRM plugin for calibre, it is necessary to install calibre first. The latest version can be downloaded from calibre - Download calibre
Installing the DeDRM plugin for calibre
The latest tools_v6.5.1.zip can be downloaded from https://github.com/apprenticeharper/...ses/tag/v6.5.1
1. Download the latest tools package, and unzip it.
2. Run calibre. From the Preferences menu select “Change calibre behavior”.
(Do not click “Get plugins to enhance calibre”, that option is reserved for ‘official’ calibre plugins.)

3. Click on Plugins (under “Advanced”) — it looks like a jigsaw puzzle piece.
4. Click on the large “Load plugin from file” button
5. Navigate to the tools folder unzipped in step 2
6. Open the “DeDRM_calibre_plugin” folder
7. Select the DeDRM_plugin.zip file in that folder
8. Click on the “Add” (sometimes “Open”) button.
9. Click on the “Yes” button in the “Are you sure?” warning dialog that appears. A “Success” dialog will appear, saying that the plug-in has been installed. Click on “OK”.
Using the DeDRM calibre plugin
The DeDRM calibre plugin removes DRM from ebooks as they are imported into calibre. So to use the plugin, just import your DRMed ebooks into calibre, and the DRM will be removed. If you have already imported your ebooks into calibre, you will need to remove the DRMed ebooks and import them again.
You can check that the DRM has been removed from an imported ebook by trying to view it using calibre’s built-in viewer. Note that for .azw3 Kindel ebooks you might need to check a checkbox in calibre’s preferences to say that .azw3 ebooks should be viewed using calibre’s internal viewer.

If things go wrong
The calibre developers are not involved in the development of the DRM removal plugin, and are not able to help with any DRM removal questions. If you have any difficulties following the instructions in this post, the calibre developers will not be able to help.
Credits
Most of the work on converting the DRM removal scripts to a calibre plugin has been done by DiapDealer and Apprentice Alf.
Now we are prepared to strip the book by her DRM protection so will follow next :
There are several ways to go about getting your DRM-loaded Kindle books. You can:

1. Mount your Kindle as a USB device and pull them off.
2. Download them using the Kindle for PC app.

Let’s look at each technique in order to highlight the benefits/shortcomings and what you need to do.
Copying the Books from Your Kindle: If you’re going to rip the book directly from your Kindle device (or use the download and transfer technique), you need to manually enter the serial number of your Kindle into the DeDRM removal plugin. Do so by navigating back to Preferences -> Advanced -> Plugins -> File type plugins and double clicking on the entry for DeDRM. You’ll see a box like so:
Click on the first entry “eInk Kindle ebooks” and, in the resulting dialog box, click the + sign and enter the serial number off the back of your Kindle.
Double check the serial number; any discrepancy between the serial number in the book file and the plugin will lead to decryption failure.
Downloading Your Books via the Kindle for PC App: If instead you have sent your Kindle books to Kindle for PC, and we strongly recommend this method because it’s so easy, you can find the locally stored books in the following directory:

C:Users[Your Windows Username]DocumentsMy Kindle Content

Each Kindle book you import to Kindle for PC will have two companion files (.MBP and .PHL files); you can ignore the extraneous file types. Books will also have odd names, like “B001QTXLQ4_EBOK”. Don’t worry the proper name and author data are stored in the files. This technique is nice because you can snatch all your books in one swoop and dump them into Calibre. Simply select all the actual book files (all the .AZW, .TPZ, and .MOBI files) and dump them right into Calibre to import them.
Now, Calibre will import any ebook file (DRM-laden or DRM-free) without a hiccup. The real test of whether or not the import-and-strip process has worked properly is to try and convert the book into a new format. Right click on the entry for the new book and select Convert Books -> Convert Individually. This will pull up the conversion menu. Convert it to any other format, it doesn’t matter which.
If the book’s DRM hasn’t been properly removed, you’ll get an error like this:
Now, this error does not necessarily mean that the DeDRM plugin isn’t working properly. If you’re loading books off your physical Kindle and you entered the serial number wrong in the DeDRM configuration, the process would fail like this. If you tried to add Kindle books that you’re not the actual owner of, it will also fail.
Load the books from the proper source, however, and the process starts successfully.
