Removing DRM move azw3 between Kindle

I don't want pirate or pirated copy books.

But I do have two different Kindle account in 2 different country.

Want read all the books on my Kindle paperwhite, here is how:

Using Calibre

Go to and download the newest version of the DeDRM tools from one of the links given there. You should wind up with a file called

Unzip it to produce the directory tools_v6.0.8.

Inside that directory are three sub-directories: Calibre_Plugins, DeDRM_Applications, and Other_Tools, which seemsreasonably obvious.

The DRM encryption scheme incorporates the serial number of the device it was downloaded to, so write down the serial number(s) of your book reader(s) because you’re going to need them.

On an e-ink Kindle, the serial number is at Menu-->Settings under the "Device Info" heading.

To install the Calibre plugin, start Calibre-->Preferences-->Plugins-->Load Plugin From File. Navigate to tools_v6.0.8/DeDRM_calibre_plugin and select Ignore the warnings.

Back out and select Calibre-->Preferences-->File Type Plugins.
Select the DeDRM plugin and click on "Customize plugin".
Enter the serial numbers of your Kindle devices, separated by commas.
Click “Apply”

Restart Calibre for the plugin to take effect.

The plugin will now remove DRM from any Kindle file being added to the Calibre library or being sent to the bookreader, but it will not change the version which is already in the Calibre database!

If you want to remove DRM from a book already in the Calibre database (to read it from inside Calibre, for instance), the easiest way is to select the book(s), click on “Save to Disk”, then import them (removing the DRM in the process) and delete the originals.



  1. Works. But is there any way to remove the DRM if the books are downloaded via K4PC (running in WINE)? I'm using Ubuntu Saucy x64, and calibre keeps telling me the books are protected when I try to convert them to .epub.

  2. I really love your site.. Great colors & theme.
    Did you build this amazing site yourself? Please reply back
    as I'm planning to create my own personal site and want to find
    out where you got this from or what the theme is called.
    Thank you!

  3. Thanks. It is the WordPress default theme, called 2014.

  4. Whoa! This blog looks exactly like my old one!
    It's on a entirely different topic but it has pretty much the same page layout and design.
    Superb choice of colors!

  5. Pretty! This was a really wonderful article. Thanks for providing this information.

  6. When I originally commented I clicked the
    "Notify me when new comments are added" checkbox and now
    each time a comment is added I get three emails with the same comment.
    Is there any way you can remove me from that service?
    Appreciate it!

  7. We absolutely love your blog and find almost all of your post's to
    be precisely what I'm looking for. Does one offer guest writers to write content for you personally?
    I wouldn't mind writing a post or elaborating on a lot of the subjects you write in relation to here.

    Again, awesome site!
