How to Remove DRM from KCR and Convert KCR to PDF

Posted by on .

What is Kindle kcr? I can not give a definitely explanation so far as it is just released about one week. All I can tell is that the .kcr file contains the main body of the Kindle books which is stored in Kindle .kfx file previously. Many of you guys maybe still have not seen this new ebook format. If you have updated your Kindle for Mac to version 1.25.2(52077), you will be “lucky” enough to meet this new Kindle format--Kindle KCR.

Since this is a new Kindle ebook format, there is no solution to remove DRM from kindle kcr file directly for now. But this is not the end of the world because I have collected two alternative methods to eliminate drm from Kindle kcr books and convert kcr to pdf.

Method 1. Degrade Kindle Desktop Application to Old Version

If you guys think degrading Kindle desktop version is unacceptable. You can just skip this method and try “Download & Transfer via USB”. But I really suggest you try this method out as the whole process is very easy and ensure 100% success.

Step 1. Deregister and uninstall Kindle for Mac version 1.25.2.

Run your Kindle desktop application. Go to Kindle-->>Preference-->>General-->>Click on “Deregister”.

A new window will pop up. Check the box before “I understand…” and then click on “Deregister” to deregister your kindle for Mac1.25.2.


Then to go Finder-->>application-->>find Kindle.app, right click on “Kindle.app” and select “Move to Trash” to uninstall the Kindle for Mac version 1.25.2.

Step 2. Install Older version of Kindle for Mac

Download the older version of Kindle for Mac here: Kindle for Mac version 1.23.

Install and run Kindle for Mac version 1.23. Redownload your Kindle books to your computer. There is an important step you should never miss. Please remeber uncheck the Kindle auto update option. Run Kindle for Mac-->>Preference-->>Update-->> Uncheck the box before "Automatically install updates when they are available without aksing me" as below picture. If you do this, your Kindle for Mac will not update without your permission, in this way you will avoid the latest Kindle DRM.
