Kindle DRM Removal - Amazon Kindle Format eBooks

If you have purchased eBooks from Amazon Kindle Store and you want to read them on any other device then you must strip their DRM Protection to use them freely.

Amazon Kindle Store eBooks

In this post, I am going to show you how to remove DRM using an open source popular eBook Converter Software. If you have any question or concerns about whether is it legal or not you are welcome to see our DRM-Removal Policy.

You may also want to try my other Unswindle (DRM Removal) Method for Kindle if you face any difficulties using Calibre. It will also help you to pass over the Kindle PID part. In fact, the Calibre method is far better and it does support more e-Book extensions of Amazon Kindle Format.

This method is working great but I recommend you also to try the most up-to-date DRM removal method which is DeDRM: Ultimate Calibre DRM Removal Plugin for eBooks.

What is Calibre (DRM Removal) for Kindle Fire Method?

This method is the quickest and easiest way to remove DRM from e-Books by Calibre (Free DRM Removal Tool) through K4MobiDeDRM (Calibre Plugin). You can also get this to work without using Calibre if you install python but it will get harder and take longer which is not necessary.

Calibre can then convert your Kindle e-Books to whatever format you desire. It is meant to function without having to install any  dependencies except for Calibre being on your same machine and in the same account as your Kindle for PC or Kindle for Mac application if you are going to remove the DRM from those types of books.

Warning : Do not send the (DRM-Free) content to anybody else and keep it only for self-use and also keep in mind that the purpose of removing DRM is to enjoy your legally purchased Books or Media on other devices.

Credits : Article, Tips and Download links are done by me (Saleem Almajed). But originally the K4 Mobi Tool and Calibre Plugins were created by (DiapDealer) and a special thanks to (Apprentice Alf) for improving the plugin.

This is only legal as long as you are the original owner of the content and you are planning to remove DRM to fully gain the right of ownership NOT for sharing it.

What type of eBooks are supported by this method?

This plugin is meant to remove the DRM from Kindle Fire Books with the extension of :
  • Mobipocket eBook File (.prc/.mobi)
  • Kindle Mobipocket (.azw)
  • Kindle Topaz (.tpz/.azw1)
  • Kindle Print Replica (.azw4)

How to install the "K4MobiDeDRM" Plugin?

It is so easy to install a Plugin to Calibre but there is something that you should consider when you are installing an Unofficial Calibre Plugin (which is the plugin we use to strip DRM). Actually, I wrote a full tutorial post on How to install a plugin to Calibre successfully. After you have installed "K4MobiDeDRM" Plugin you should proceed to the next step below to configure it.

In order to run Plugins without Calibre, you will need to install Python for Windows (Mac already comes with Python, but apparently has older versions).

We strongly recommend ActiveState's Active Python 2.7 Community Edition for Windows (x86) 32-bit.

How to Configure the Plugin "K4MobiDeDRM" to work?

Move your mouse to highlight the plugin (K4MobiDeDRM under the "File type plugins" category) and click on the "Customize Plugin" button and a dialog will appear like the Picture Below.

Configuration of the Plugin "K4MobiDeDRM"

So, you need to enter your Kindle PID into the dialog with your Serial Number which is either 10 Digit PID or 16 Digit PID.

10 Digit PID

Enter your 10 digit PID and If you have more than one PID separate them with a comma (no spaces).

16 Digit PID

If you have a standalone Kindle then enter the 16 digit serial number (these typically begin "B0...") in the dialog (again separated from the PIDs or other serial numbers with a comma (no spaces).

This configuration is not needed if you only want to decode "Kindle for PC" or "Kindle for Mac" books.

How to remove DRM from eBooks by Calibre?

Once The plugin is installed and configured, you can simply add a "DRM-ed eBook" to Calibre and the "DRM-Free eBook" will be imported into the Calibre Database.

Add & Convert eBooks with Calibre
