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 three 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. Updated: You can automatically downgrade Kindle for Mac to older version with the help of Epubor Ultimate.

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”.
