Kindle DRM Removal, Easily Remove Kindle DRM AZW [Infographic]

Posted by on .

When we paying money for a Kindle book, we are only allowed to rent them from the Amazon store instead of truly owning it. In fact Amazon adds Kindle DRM on their digital books which bind us with his Kindle devices or Kindle app. So if we want to read our purchased Kindle books more freely, the Epubor Ultimate is needed.

What is Kindle DRM?

Kindle DRM is a "Digital Rights Management" technology adopted by Amazon Kindle. So for us customers maybe it is difficult to understand what it is on earth. But I think you may start to know it after reading these examples below. kindle drm

You bought a Kindle book and transfer it to iTunes, but iBooks told you that you can't open this book!

You found an interesting Kindle book and you were so happy that you can't help sharing it with your best friends, but when she opened it Amazon lets him purchase a copy from the Kindle store!

You often bought books from amazon.com and also japan amazon, so you need to switch account on kindle eReader if you want to read different books (different languages)!

Amazon may delete your purchases (and even your account) from your Kindle Cloud without saying anything. So some Kindle ebook buyer may find that their purchased books disappeared from Kindle Cloud!

Yes this is Kindle DRM. Kindle DRM definitely has no benefit but only inconvenience for we customers and readers .

Why We Need Epubor Ultimate

1. I want to read my Kindle books on iPad iBooks, not only on Kindle paperwhite, or with kindle app.

4. I want to print my Kindle pages to paper.

5. Save my time to download the same book on several different devices. It makes me angry when there is no Wifi but I must download the book before reading.

Method 1: Remove Kindle DRM from Kindle for PC/Mac

This is the most reliable method, no matter you have a Kindle device or not. You just need a Kindle desktop reading app, and make sure you can read your books on your computer first.

Download Kindle for PC Download Kindle for Mac

Step 1: Register Kindle App

Get this Kindle desktop reading app started. The first time you run it, it will ask you to register. On the "Register Kindle" window you just need to input your Amazon account and the password.

register kindle

Soon you will see your own Kindle library. These books are those ones you bought from kindle store with your account.

Maybe some books already have been downloaded (Archived Items), while others haven't been downloaded yet (Downloaded Items). Double click on the cover to start downloading the book.

But for successfully removing kindle DRM, you must make sure that the books which you want to remove their DRM are downloaded well to your local computer. In other words, you must make sure you can see these books in "Downloaded Items".

All the downloaded items are saved well on your local computer.

How to find the downloaded Kindle books on PC?

Failed to remove DRM from Kindle for PC (.azw) 2018

If you found that after adding books to epubor ultimate, it failed to help you remove the DRM, the highly recommended solution is checking your kindle for pc version(Help > About Kindle).

kindle for pc 1.25

If you found that your version is 1.25, please uninstall your kindle desktop from your computer (now neither Epubor nor Calbire could help directly handle this new drm scheme), and delete the "My Kindle Content" folder from your computer, then download the kindle for pc 1.24 please.

The current and unique solution for this problem is downgrading your kindle desktop to older version!

Step 2: Run Epubor Ultimate Software

At first glance you will see the clean interface, it is way easier to operate than Calibre Kindle-DRM removal plugin. So this tool will be your best choice if you are not familiar with computer skills.

kindle drm removal

This tool displays the built-in kindle library clearly on the left side. One of its wonderful functions is that Epubor Ultimate can automatically detect all your Kindle books that already downloaded to your computer via Kindle for PC/Mac.

Drag them to the right area. Epubor Ultimate will help you remove drm from kindle books in batch at once. Once finished please click on the blue button "Decrypted" to open the output folder where those eBooks are stored.

In most cases, the book format (originally was .azw) will be changed to .mobi or .azw3 after drm removing. But don't worry it just removes the drm limitation, no change to your book files' quality and content.

Method 2: Remove Kindle DRM from Kindle E-ink eReaders

This method will be easier than method 1 if you own a Kindle e-ink eReader, as this Epubor Ultimate can detect the device and sync books automatically. And there is no need to install the Kindle for PC or Mac app.

Step 1: Download books to Kindle E-ink device

On Kindle there are some books are saved in "Cloud", and others are saved on "On Device". So for successfully removing DRM it is necessary to make your books download to your Kindle device.

downloaded to kindle e-ink

Step 2: Plug in Kindle and run Epubor Ultimate.

Connect your Kindle to computer with USB cable and run Epubor Ultimate. Soon on the left side layout you will see your device and your book files list.

Multiple Kindle devices plugged in at the same time are supported as well.

Step 3: Drag books from left side to the right blank area

Select the books and drag them to the right blank area. You will be surprised that this software can remove DRM so fast without inputting KSN! In fact it can read the basic information of your Kindle when detecting your device, including the Kindle Serial Number.

remove kindle drm from eink

Why I found that not all my Kindle files are listed under the device name?

This software can only read your Kindle books that saved in your Kindle "Documents" folder. So when meeting a problem like this, please check the "Kindle" drive on your computer and copy them into the documents folder.

But if you want, you can also click on "Add" button to choose files from your local kindle drive.

Update on 9/10/2015: You can also get a trying to remove drm from your Kindle paperwhite by online service. This online Kindle DRM Removal is provided for you. It's totally free.

Epubor Ultimate can handle Kindle KFX DRM 2017

From 2017 you will find that some Kindle books you downloaded from amazon store are kfx format, though after synced via Kindle desktop they are still with .azw extension. This is because Amazon changed their DRM encrypting technology and in fact it's unique so that on the market no tools could help us remove DRM from kfx books unless you downgrade the Kindle desktop to version 1.17, what's worse the steps are a little messy.

But good news is that, since 19th, October 2017, Epubor team worked out the solution (and we're the first one who found the method) and soon upgraded our Epubor Ultimate.

There is no difference to us to finish our work, as it will automatically detect and display your kfx files.

If your books are downloaded via Kindle for PC/Mac, kfx books will be .azw, but don't worry what you need to do is adding them to start the drm removing processing.

If your books are downloaded directly via Kindle e-ink devices, epubor ultimate will automatically detect them, as the image shows below.

epubor ultimate can handle kfx drm 2017

But the step that different from above methods is that, after drm removing the decryypted file is still kfx format (_nodrm .kfx).

decrypted kfx

The problem is, you can only open the decrypted kfx file with Kindle devices or apps, you can't open them via the third-party reader app such as Calibre. It will recognize the file as KFX-ZIP and when you try to open the file calibre will let you select another app.

calibre can't open no drm kfx

So if you want to read your Kindle KFX books on non-Kindle devices, you'be better convert them to Mobi/AZW3 or EPUB/PDF format. Please note that what I mean is non-Kindle devices, not non-Kindle-supported devices, you know, there are some apps that support Kindle books format, so after you removing drm with method 1 and method 2, there is no need for you to convert their formats.

must convert kfx format after drm rmeoving

Tips: In general it's easy to successfully remove drm from your kfx files if you followed the steps I introduced here. But if you still met problems you can have a good lood at this guide Kindle KFX DRM remove failed and solution.

Method 3: Remove Kindle DRM from Kindle for Android App

I won't recommend you remove Kindle DRM with this way unless you can only download Kindle books on a Android tablet or phone.

I believe there are few people will try this method. If you don't have a computer, how can you free download this Epubor Ultimate? If you have a computer, why not try the method 1?

  • It only works for android 4.1 (or lower version)
  • You should install a third party (special) Kindle for Android
  • Have to try again and again by manually inputting the PIDs

If you have to do so, or want to do so, follow the steps and keep patient please.

Download Kindle for Android

Step 1: Open books and find PID list

Get your Kindle android app started, log in with your own amazon account. Find your purchases and click to download.

How to find PID from Kindle for Android?

Open some books and slide some pages (remember that only by books opened, the PIDs will be generated). Then visit "Info - About - PID List" to see those PIDs.

open pid from kindle for android

See? There are so many PIDs that you should try one by one. And often each PID does have capital letters, small letters and Arabic numerals, which will bring you inconvenience when inputting. Calm down and be mindful.

Note: If you haven't opened any book files, when you click "PID List" you will see some words: Open DRMed books to show PID list.

open to find pids

Step 2: Find books and add them to remove

Kindle books synced via Kindle for Android are in PRC format. And they are stored under "/com.amazon.kindle/files/". So please search them on your android.

find files

find prc

Then copy the books to the software. When books added, this software will pop up a window that lets you input the PID.

remove kindle drm from kindle for android app

Tried all the PID correctly but failed finally. Why?

The PIDs will change each time when you open different books. So please open your book and slide some pages so that the PIDs have been fully written down to your Android without any problems.


Point 1: From 2015.1.21, Japan Amazon starts to provide the downloading of Kindle for PC(win 7, 8, 8.1) desktop reading app (click here to read more). So congratulations that for Japan kindle users now you can remove drm easily with method 1, rather than this difficult way.

Point 2: Kindle Android KFX

From Kindle for Android v7.2 or later, all the downloaded Kindle files will be kfx format, but not the PRC. The location of the main book folder will be something like "/Android/data/com.amazon.kindle/files/Bxxxxxxxxx/CR!xxxxxx.kfx" files.

android kindle kfx

Most of these KFX files have DRM. As far as I know, there is currently no working method for DM Removal from the Kindle for Android App. So in this situation we can remove kindle drm from Kindle desktop or kindle e-ink devices.

Use Epubor Ultimate for yourself, not for piracy

Even though there are a lot of reasons that we need a Epubor Ultimate for better reading, but the basic principle is: We must use it just for ourselves!

The key to remove Kindle DRM is based on your own purchases, and this is also the reason why this tool needs you log in your amazon account, or KSN, or the PID. They are all linked to yourself.

You can transfer your books to multiple different devices, back up your kindle books, share them with your friends, and so on. But no reselling!

A video guide of Epubor Ultimate tool

At the last part I still want to share a powerful useful video guide with you, which includes the latest solutions to remove Kindle drm.

Downloaded .exe file (drm removal file), tried 3 times to run it.  Ran extremely slow, then quit with "network error".  Other files from other sites downloaded just fine, no errors on running setup files.  Downloaded .exe file second time, thinking maybe first download was corrupted - same result.  I give up, file download does not work for me.

Your software does nothing for the new protection from Amazon it seems. Downloaded book is downloaded into a folder inside the kindle content folder. Has several files with it. A tmp folder, .azw .voucher and .azw.md   There is nothing in the tmp folder. But none of these files will work with your program. Any help?

I'm having the same issue as "Me". I download my kindle books locally to my PC. Then I add the to the Kindle DRM remover app. The books are downloaded as .azw files. If this can be remedied, I'd gladly pay for your software!

02/4/2017 20:19:54
I replaced the new version of the Kindle program with the previous one: KindleForMac-44182-2 and it works again.
02/9/2017 20:24:49
Same issue as "Me" and "Brian". The Kindle ebook is downloaded to the PC into a folder inside the "My Kindle Content" folder. Several files are contained : .azw, .mbpV2,.voucher, .azw.md, .azw.res and an empty tmp folder.
Epubor Kindle DRM Removal says (in French): Unknown error.... your book is protected by DRM we do not support.
02/15/2017 10:25:00
Because Kindle for PC/Mac has automatically upgrade to v1.19, that makes kindle books are changed to KFX file format.
Please downgrade to v1.17 or older version.
More details:
02/27/2017 04:44:05
The downgrade does not work for me.  azw.res file gets error message.

Likewise. Still not fixed. Doesn't work for me.

Sure, you can, it's easy, why not download the software to have a try.
09/2/2017 16:24:53
Just wanted to comment on here and say that as of September 2, 2017 this program works. I converted an .azw file to .mobi file and then from there converted it to .pdf as I had desired. No apparent issues so far. Great program!

Thank you for your comment!Glad to hear that.

As of Sept 12, 2017, recent Kindle purchases failed to be converted by this program. I suspect this is because of a change in encryption scheme by Amazon. At least when served to the Mac version of their Kindle app. So caveat emptor: the Epubor's application is now mostly useless, until they catch up to Amazon

I can't write what I want
12/16/2017 17:51:46

Running Windows 10. Free trial of this software down loaded fine. I ran the DRM removal on a kindle book I had dropped onto my PC. It stripped the DRM, left me with TXT file which I then loaded into MSWord, reformatted into something intelligible.

Reasonably satisfied.

01/4/2018 09:42:35

I followed all the instructions.
It worked good, BUT, it does not convert the entire book, just the first couple of chapters.. why is that? So yes, the tool works, but it is in a way useless, because I need the entire book, not just the first chapters.


01/10/2018 09:55:22
The trial version only can decrypt 20% content of each book. So you may try the licensed version to get the full content of this book.
01/4/2018 10:05:24


I could not convert the complete book, it only converted part of it.
BUT, when I used your online tool it worked PERFECT!!

thank you so much!


02/1/2018 01:21:05

same problem with azw.md files, not working


02/1/2018 10:20:20
azw.md file is metadata of this book, there is no need to decrypt it. For more information about kindle kfx, you can read this article "All Things about Kindle KFX You May Want to Know". It explains very file on your book subfolder.
