Origin of the Tools

The tools for removing DRM from ePubs were originally posted at i♥cabbages’ blog. The tools for Kindle/Mobipocket were originally posted at The Dark Reverser’s blog.

They have since been improved by many people, but mostly some_updates, DiapDealer, Apprentice Alf, and Apprentice Harper. While there are many sites that redistribute these tools, the most up-to-date versions of the tools are currently released here.

Other Sources

Anyone trying to sell you ebook DRM removal tools for Adobe Adept ePub and PDFs, Barnes & Noble ePubs, Kindle ebooks, Kobo ebooks, or eReader ebooks has probably just repackaged (an earlier) version of the tools available here.

  1. I am trying to help someone strip the DRM from Kindle books, but she does not own an actual Kindle and only reads her books via Kindle for PC and Kindle for Android. From what I can tell, neither of these display a serial number on Amazon Content and Devices in the way that a serial number is displayed for an actual Kindle. For my own books, I am using the Download for USB option to get a book copy in a version I can decrypt, but I have an actual Kindle so I have a serial number. How does one get a serial number to use when one does not own an actual Kindle?

    • None needed. As long as the Kindle for PC app where the books are downloaded and calibre with the DeDRM plugin are on the same computer and user, then the key will automatically be retrieved.

    • Just download the book to Kindle for PC on her computer, then import the book into Calibre (assuming you have installed the DeDRM plugin) ON THE SAME COMPUTER.

      • The one problem with this is that some of us are more technical than others … if you know what I mean … and she lives quite a ways away, so tech support is difficult. Once it retrieves the key, can we then inspect the list of serial numbers and add it to my machine?

              • The goal is to allow bi-directional sharing between sisters who are separated geographically. At our end, the DRM is being stripped on the load to Calibre, so the files are ready to share. What we are looking for is a way for her to share selected books with my wife. Because of the lack of technical expertise at the remote end, the ideal would be for me to be able to remove the DRM. If she had an actual Kindle, then she could merely send me the USB download file and I could load it into Calibre using her serial number, which would be ideal since I would be the one doing all updates and the like. Getting her set up to be able to strip the DRM is a possible solution, but more complex because it has to happen outside of my control.

                • The only way to get the Kindle for PC key is to have it and calibre with DeDRM on the same machine. And that key will only work with books downloaded to that installation of Kindle for PC. If she ever switched computers or even re-installed it on the same PC, the key would be different.

                  Another possible solution is for the two sisters to link their accounts with Amazon Family. No DRM removal necessary. This only allows 2 adult accounts to share though.

                  • The Amazon books published here are actually bought under my account because I happened to be the one that started using an e-reader first. I will have to look up about Amazon Family since I know nothing about it.

                    I understand about the Kindle for PC key … but, does this even matter if we go the route of the KFX plugin?

                    • To help your wifes sister to install you can use Teamviewer.com to remote control her computer and do the setup for her. That is saving me many hours of phone-bills and hair-tearing each month helping family in different countries with their computers.

                    • We are familiar with Teamviewer as my wife uses it a lot to support a friend. Sister is here right now, so we don’t need remote tools.

          • Hi! I have some recent tech issues and would greatly appreciate help. What is the address or link which I should use?
            Thanks! Robert

          • Not sure, how it would be of much use, but:
            The keys for Kindle for PC/Mac can be exported from the plugin on her (!) computer.
            The ebooks must be downloaded (fresh, after installing DeDRM) on her computer, and then DeDRM should work on her computer.
            As far as I have learned, the Key for each installation (device) is different, so when you try to DeDRM the ebooks on your computer, you must use the freshly downloaded from her, adding to the hastle, you already have.

            As I have worked in an IT-Helpdesk, the simpler solution would be to both install TeamViewer and configure everything for her on her computer with TeamViewer.
            If it does not work, get back to us with a log or more questions.

            Also, Kindle for PC/Mac in the newer versions loads KFX, which adds to the problem, the support is now there, but does not always work, imho. If possible, use a older Kindle for PC/Mac Version 1.17.1, which only loads the simpler, older filetypes. Install that, turn of “check for updates” in the settings. A word of warning, a quick search for the version only found saved ones, without being really sure, wether it was with added SPAM/Trojan/Virus. Be careful what you get, if it is not available on Amazon anymore (not sure).

            She should then login with her Amazon credentials and download the books fresh and DeDRM should retrive the key from the setting on import (Calibre-Plugin) or selecting the file for DeDRM (standalone app).

            • What I have been doing for my own books is going to Devices and Content and downloading each new title with the upload via USB option to get a file that does not have the KFX format. This has worked on my own books so far, while neither the copy in the Kindle itself nor the one in Kindle for PC (prior solution) works.

                • So, if I get this KFX conversion input plugin and install it in my copy of Calibre, I should be able to load the Kindle for PC files from her machine and convert them to other formats? If so, that sounds best.

                  Do I understand that, in the Kindle for PC directory on her machine, some files are in the directory itself (no DRM or old format?) and some are in subdirectories by book (KFX?).

                  • KFX books are multiple files. When you add the main file to calibre, the KFX Input plugin gathers up all the related files. Might work if you had the whole folder. I don’t know if later versions of Kindle for PC put the old format in the main folder and only KFX in their own folder. I think it puts all formats in their own folder. But I’ve stuck with 1.17 myself so I don’t know.

                    • So, to try this out we would need here to send the whole folders. Seems doable.
                      She has 1.23.1
                      I have only had a quick look at her machine (she is currently here visiting), but I think the ones not in subfolders were books that were unlikely to have DRM and likely to be old. She doesn’t actually have very many books, unlike our 1400.

    • OK, let me back up and try again … we just had a conversation about all of this over lunch and the target has moved. She is now uninterested in having Caliber on her machine and does not want a large volume of books. So, for the us to her direction, I can easily e-mail her a copy of any of our books which has already had the DRM removed.

      What we need to test now is sending her a copy of a book and see whether it works to simply put it in the Kindle for PC Content directory. I am fairly sure that will work for Kindle for PC, but she doesn’t actually read books there. She reads on an Android phone. There is some setup, which I know nothing about such that any new books added to the Kindle for PC sync to her phone. If this happens with us just copying a book into the Content directory, then we are set for the us to her direction.

      What remains, however, is the her to us direction. I had been thinking that the KFX plugin would allow me to read a copy of the contents of her Contents directory, but I gather from the discussion that it won’t handle the DRM so I still won’t be able to convert it to EPUB for my wife to use. So, is there any way to handle the DRM at my end? Or can she use the USB download? Or what?

      • Note, have tried Download for USB on her account and it is not available since she has no applicable devices.

        • Yes, it’s only available for Kindle devices. And the key is only tied to the serial number on E-ink Kindles, not Fires. You could keep an eye out for a cheap, refurbished E-ink Kindle (any generation) and link it to her account.

            • Well, not doing well. We tried emailing the file to gmail, but can’t seem to control the download location or move the file. I attached my phone via USB and found the attachment and found the folder which appeared to be for the Kindle books and moved the file there, but it doesn’t show in Kindle for Android the way it does in Kindle for PC. Looking further, I see that the books in Kindle for Android are .prc files, not .azw files, so I don’t know that it is even in the right format.

              • I was able to sideload AZW3 files to Kindle for Android on my phone. I was able to do it by downloading one from gmail and transferring another by connecting to my PC via USB. To move files around on the phone itself, you need some kind of file explorer app. I just used the built-in Samsung one on my phone. Once you put them in the Kindle folder, open the Kindle app and tap On Device.

      • Seriously sounds like Amazon Family Library would be a better solution than all of this:

        https://www.amazon.com/gp/help/customer/display.html?nodeId=201620400

        Then if your wife needs it in epub format, you can DeDRM it just as if it was from your own account.

        Back to without Family Library…
        She could open DRM-free Kindle files on her computer with Kindle for PC, but they wouldn’t sync with her account. You could look at the “send to kindle” email option.

        The KFX Input plugin just allows you to use DeDRM with KFX books.

        • The household thing appears to share all credit and debit info which, as Amazon themselves says, may not be something you want to do.

          I was avoiding the send to kindle idea because it seemed like a bad idea to send back a title which had the DRM removed … sort of giving them the evidence, if you know what I mean.

          • Oh, I had forgotten about that. I share with my husband so not a problem. I think you still have to explicitly say which if any cc you want to share. But it may be a little too easy – I don’t remember.

            Anything that syncs to her account would probably be “giving them the evidence.”

          • Just so you know, a Kindle eInk which has WiFi set up (as most people will do) phones regularly home, as I recently verified, even daily when Sleepcover is closed and the Kindle is supposed to be in Sleep-Mode. Also a reason why an unused Kindle does not stay charged for more than a few weeks. I was rather surprised by that, and my guess is most people do not know it.

            The Apps are linked to the Cloud at Amazon. So they already know anyway, Send to Kindle will not make a difference. My guess is, they do not care (yet?).

            • We have solved the us to her part by connecting the phone with a USB and copying the DeDRMed file from the PC to the phone.

              We are stumped on the her to us part for the present. Since we can handle us to her without using Calibre and she has no interest in learning another program and the volume of books will be small, this means no tools on her PC. So, short of adding a device which will allow USB downloads, I’m not clear where to go from here.

              • Do you ever use Kindle for PC yourself? If not, you could install it on your computer and have it logged into her account. Or you could add another Windows user and set everything up there. That’s the only other way I can think of.

                • Interesting… I was going to say that I had Kindle for PC on my computer, but that it was only there because for a period after I got my new Paperwhite I loaded Calibre from the Kindle for PC. That, of course, stopped working with the move to 1.19 and I switched to the Download for USB approach. But, when I went to check on the version number, I discovered that I have switched PCs a while back and there is no Kindle for PC on this new box. So, I guess I could download a copy of 1.17 and use that.

                • So, to be sure, if I install Kindle for PC 1.17 on the machine where I use Calibre, all I need to do is to download all of her titles and then load these into Calibre and the DeDRM software will automatically detect the key. Since this will be using 1.17, I assume I will not need the KFX plugin. Right?

            • All that said above and by others re Kindle. Is it absolutely necessary for people to use any kind of Kindle reader? I have never owned one and will never ever. I buy books quite often from Amazon and DeDRMed them with this tool and Calibre and load them on my preferred reader. Never had an issue.

              So having a Kindle reader must be for more than just reading. What don’t I know about having a Kindle reader?

              • I agree with DRMfreed’s comments. I use Kindle for PC v1.17 to download my ebooks (which I assume she/he is also using). No need for an actual physical Kindle Reader. What are we missing?

              • For me, the Kindle is a preferred reading mechanism. The phone is too small and the computer to large or heavy. I have a strong preference for the PaperWhite screen, even over many books, as a image for reading.

                • Fancy that! To each, his own for sure. Thanks for sharing that tamhas.

                  @SJL, I do use K for PC v1.17 as well and will forever do as as long it works.

                  Peace all

                • To me the Kindle format sucks big time! I prefer ePub and use MapleRead SE on my iPad Mini. I use Kindle for Mac 1.17 to get books, then convert them in Calibre to ePub.

    • Looks like you trying to install the wrong file. You only unzip DeDRM_tools_6.60.zip. Make sure you haven’t unzipped any of the files inside it. Look in the DeDRM_calibre_plugin folder. Load DeDRM_plugin.zip into calibre.

  3. Hi, I tried to import a Kindle book into Calibre, using both the Kindle on PC method and the actual Kindle device. No joy both times. Here is the debug log, can you take a look? I noticed the book is 1000’s of pages in Kindle, but the AZW file on the PC or the KFX file on the Kindle are both very small…

  4. I’ve used this tool several times before without issue. Now I’m getting errors:

    There is 1 ebook to be decrypted.
    Processing file: B06XKN9G27_EBOK.azw
    There was an error with 1 ebook:
    Macintosh HD:My Kindle Content:B06XKN9G27_EBOK:B06XKN9G27_EBOK.azw is neither a Kindle not a Mobipocket file.

      • I don’t know whether or not the stand-alone tools can deal with it, but you can create a KFX-ZIP file by creating a ZIP archive of all of the files in a book subfolder within the main Kindle for PC/Mac content folder and then changing the file extension from “.zip” to “.kfx-zip”. (If the book folder has a file whose name starts with “amzn1.drm-voucher” then it is in KFX format.)

  5. Hey guys,
    It’s the first time I’m using this tool, i got both plugins and they’re up to date, but my ebook still seems to be unconvertable…

    here is the log :

        Thats the log 🙂

        • searching for kinfoFiles in C:\Users\Soufian\AppData\Local
          No K4PC kindle.info/kinf/kinf2011 files have been found.

          That book appears to come from Kindle for PC. DeDRM needs a file that should be present if K4PC is installed, but it was not found.

  6. I’ve given the kfx functionality a try. Importing a kfx book is working flawlessly so far on Windows 10, but is failing to decrypt with any of the eink keys entered into Linux. Am importing directly from a Kindle Oasis. The log shows that the voucher is found but can’t be decrypted with any keys. It then proceeds to try to extract a key with wine, which of course is not configured. I have not posted a log because I gather this is not intended to be working with Linux at this stage? Is this correct? Would a log be helpful? Or a bug report?

    • I believe it should work if you have your Oasis serial number entered into the E-ink Kindle section of the plugin correctly. It’s only trying to get keys out of Kindle for PC under Wine that gets tricky.

      • Thanks Laura. Interesting. I checked the key is correct by way of importing an .azw3 which works normally. It’s actually the decryption step that seems to be failing. I’ll investigate a little further and post a bug report if I think it is in fact a bug. Do you know if anyone has had success on Linux?

  7. Are there any plans to DeDRM audio files, specifically Audible files? I have accumulated a large Audible library over the years. Unfortunately, the newer versions of the Audible player overload my phone and I can’t use it to access them.

  8. Are there any plans to update the deDRM tools to 64-bit on macOS? I’m currently on 10.13.5 with ADE 2.0.1, KindleForMac 1.17 and version 6.60 of the tools, which will probably stop working, after 10.14 is released later this year. I also use inAudible to deDRM my Audible audiobooks (which is probably also 32-bit).

      • Thanks for the tip, Paul! I’ve tried saving opening the Mac application in AppleScript and then re-saving it, but when I do that, I can no longer de-crypt Kindle books. (“The was an error with one book; could not decrypt”). Decrypting .epub files seems to work. I’ll try again at the end of the week.

    • Is there any difference in .kfx format and .azw3? You know I used that method to keep Kindle PC making in .kfx before this new update rolled.

      • Yes, azw3 is the older kf8 format that these tools have been able to DeDRM for a long time. The ability to DeDRM the multi-file kfx format was just incorporated into the tools a couple months ago.

        • No, I mean if it makes any difference to the DRM’ing at all. Should I keep my modified Kindle for PC that turns kfx into epub or something or reinstall it and use the new release

          • From what I understand, if you’re converting to epub, you’re better off sticking with the methods of getting the older Kindle format because they’re more alike.

  9. I suspect I’m just hosed, but thought I’d ask before I gave up…

    I have a number of old PDB Fictionwise books. To modify the DeDRM plugin so that it has a key to decrypt the PDB book, I need to enter three pieces of info:

    an identifier for the key
    my name
    the last eight digits of the credit card

    What does one do if one can’t remember a specific credit card number from eight years or more ago? Or am I just, ya know, hosed?

    • And it must be the name exactly as associated with that account too. Unless you have some old emails from that era with the information, you might be out of luck. Although I suspect that the key length for PDB encryption (which I don’t know, but is probably quite small) might make brute-forcing the key possible with a modern computer and compiled code (rather than interpreted python).

      • Luckily it turns out that not only did I save all the receipts, I also saved all the credit card numbers associate with the Fictionwise books, and so was able to generate the decryption codes. I remember starting to do that before B&N purchased Fictionwise because under the PalmOS, when Fictionwise upgraded the eReader app, you had to re-enter the card numbers to unlock your books, so I started keeping a record of the old numbers every time I was issued a new card.

        Saved by Nerd Paranoia once again!

        • And free new purchases soon after you get them! I try to keep on top of my own…although the only one I’d expect to lose access to any time soon is B&N who I don’t really buy from anymore anyway.

  10. I’m unable to open the DeDRM Tools 6.6.1 on my macOS High Sierra 10.13.4. If I right click (or control click) the icon, all I get is a warning that “The application “DeDRM” can’t be opened.” Same thing if I hold down the option key when double-clicking on the icon. I’ve tried to change my security settings, but the only options I have are to open apps from the App Store or from Identified Developers. There are no options to open “any”, which is supposed to be an available option when trying to open software from an unidentified developer. Would love it if you could please give me some advice as to what to try next? Thank you!

    • It doesn’t work for me either, while 6.6.0 does. I’m guessing that the new packaging script has gone something slightly wrong. You’ll just have to wait for 6.6.2. (I use the calibre plugin. Mind you – I haven’t tested that yet, either.)

      • I noticed that in the 6.6.1 calibre plugin the line endings of the files changed from Unix style to Windows style. Perhaps the Mac problem is a result of that.

  11. I downloaded the new 6.6.1 but my calibre cant read the kindle books. I am using a mac os high sierra and I keep getting this message: calibre, version 3.7.0
    ERROR: Could not open e-book: Failed to read book, /Users/mikaylagreenwell/Calibre Library/Unknown/B00DB32SR6 EBOK (48)/B00DB32SR6 EBOK – Unknown.azw click “Show Details” for more information

    It worked for one book I had on my kindle on my mac but it wont work for any others. What can I do to fix this?

  12. I installed kfx input plugin + de-drm tools 6.6.0 but calibre still gives me an error message – ‘This book is locked by DRM’. Help?

  13. For the record, does this drm removal tool work on kfx books that I got through my Amazon Prime Membership? If I am on Amazon Prime, do I own the book that I get to read on my ‘Kindle for PC ‘ or technically is it rented out to me ? Appreciate any advice.

    • If you’re talking about the Prime Reading program, then those are borrowed (only so many at a time, not yours if you cancel Prime). There’s also Amazon First Reads — Prime members get one of those for free per month. Those are yours to keep and will work with DeDRM.

  14. Please help me debug.

    • This log doesn’t show you adding the book to calibre so we can’t tell what went wrong with DRM removal. But it sounds like KFX Input wasn’t able to gather all the necessary files for the book. Try adding the book directly from the Voyage.

  15. Okay, this is from the kindle directly. Here’s what I got:

  16. I also got the same message. The book that I’m trying to import is in a subfolder within another subfolder. The inner subfolder is called attachables. The metadata is in the outer subfolder, called assets. The assets subfolder is in a folder named after the book, along with a bunch of other files. Am I grabbing the wrong thing? This and the metadata are the only kfx files. The rest are other kinds of files.

    • You need to locate the main KFX file for the book and import that. It will be a file in the “documents” folder of the kindle with a “.kfx” extension. It will not be in any of the “.sdr” subfolders.

  17. I can’t seem to remove the DRM from a Nook comic. I’m using the Windows Nook app on Windows 10 since I can’t get Nook Study to connect anymore. Now, I can download a regular book, try opening it with Sigil and it tells me that the book has DRM. I import the book into Calibre and can open the book, so deDRM seems to work.

    I just bought a comic. It downloads as an EPUB, but when I drag it into Calibre and try to open it, I get the ‘This book has DRM message’ in both Calibre and Sigil.

    • I don’t think you can download Nook comics to Nookstudy (or Nook for PC) anyway. Their DRM is set up differently from regular nook books with the information from the “rights.xml” stored in a separate database instead of inside the epub. The database is inside the same hidden folder where the Nook app puts the epubs, and it’s called NookDownloads.db3. The info you need from there is in plain text. So you can copy it out, name it “rights.xml” and stick it in the epub. Then DeDRM will work on them. The resulting file will be DRM-free, but not really readable in anything but the Nook app. Although you can pull the images out, and make a regular digital comic since they are just a series of full page images. For more details see this comment:

      Happy to help if you questions. Needless to say, the lesson from this is don’t buy comics from B&N!

      • Hi Laura, thanks for the response. I followed your directions and when I import to Calibre and try to open the EPUB, I still get the DRM message. Any other ideas? At this point, I feel like I wasted $22.00.

        I’d bought comics from B&N years ago and before purchasing this one, I tried downloading one of the old comics and it worked. But the one I bought last night, no dice.

        As an experiment, I thought I’d try and install Calibre on a new computer. But since I can’t run Nook Study, is there a way to get the Barnes and Noble key from the Nook Windows app?

        • Just go into the plugin customization and enter your B&N account email and password to retrieve your current key.

          When you are copying the info for the rights.xml file, be sure to copy all the way to the closing “/adept:rights” tag with the forward slash.

          If it still doesn’t work, post a log. We’ll figure it out.

          • Okay, I did manage to generate a key on the new PC and I know the key works, because I downloaded a traditional book I’d bought from B&N. I couldn’t open the book in the B&N ePub folder, but I could open it after importing to Calibre. So I tried with the new graphic novel and I get the same results. DRM is not removed.

            When I copy the info for the rights.xml, I am copying everything from “?xml version=”1.0″?” to “/adept:rights” (including the brackets that I can’t post here).

            When you say ‘post a log’, how do I generate a log?

              • Okay. Here’s the log:

                • Okay, something’s off with the rights.xml file. Take one of your regular Nook epubs before DRM removal, unzip it, and look at its rights.xml. Compare its general format to what you’re copying out of the database. See if you’re missing something or have something extra in there.

                  • Success! And in the end it was so simple. There’s a section in rights.xml that should be (all brackets replaced with quotation marks):

                    “permissions”
                    “display””/display”
                    “excerpt””/excerpt”
                    “print””/print”
                    “/permissions”

                    But copying from NookDownloads.db3, it looked like this:

                    “permissions”
                    “display/”
                    “excerpt/”
                    “print/”
                    “/permissions”

                    Correcting that fixed everything.

  18. Hi Laura,

    Could you please help me out? I downloaded a book from Amazon into my kindle and opened it in my Calibre to get DRM removed. Unfortunately it isn’t working. I’m using the latest de-DRM plugin 6.6.1 so that I can convert the DRM’d source file into drm-free epub but no luck. The file I am getting is a kfx-zip file which still has the DRM and cannot be converterd or opened in calibre book viewer 😦

    Here is the debug log –

  20. I am trying to import a kindle book I purchased today (6/15/2018) from Amazon into calibre 3.26.1 on a MacBook pro (macOS 10.13.5) and it simply won’t import (I never get to the point where I can try converting it), even after installing the most recent DeDRM plug-in.

    Thank you very much

  22. Hello 🙂

    Please help… I bought kindle version of a book today from Amazon. I want it as PDF so I can read it on other devices. I tried to convert it on calibre. Unfortunately, it’s KFX-ZIP and would not allow me to convert it because of DRM. I have all the plugins. Please, please help me convert it to PDF. Thanks in advance.

    • If you downloaded to an E-ink Kindle, then you need to enter its serial number into the plugin customization. If you downloaded it with Kindle for PC/Mac, then calbre with DeDRM needs to be on the same computer and user.

  23. DeDrm plugin is not woriking in Calibre. I get the following error message

    • There’s been a long-standing issue with some Linux systems where DeDRM can’t find python under wine. (You do need to have Python and Pycrypto installed under Wine.) A workaround is to manually run the key retrieval script under Wine, and import the key into calibre.

      See the log for the command to run:

      wine python.exe “/home/rcihard/.config/calibre/plugins/DeDRM/libraryfiles/kindlekey.py” “/home/rcihard/.config/calibre/plugins/DeDRM/libraryfiles/winekeysdir”

      You may have to create that directory first, then you’ll find the key there. (You can put it someplace simpler, like “/home/rcihard/winekeysdir”)
      Look in the plugin customization to import the key into calibre.

  24. It seems that I can’t open the app in macOS 10.13.5; it merely appears like “The application “DeDRM” can’t be opened.” Would you like to have a look?
    Thanks~

    • I think this is a known bug. You might have to drop back a version or two to get a version that works, if you don’t want to install calibre and the plugin. (I recommend calibre and the plugin)

      • More a feature, than a bug: safety measures have been tightened with each newer Mac OS version.
        Apps which are not from the Appstore from Apple must be allowed to be opened.
        While there is a setting to generally allow that, it is considered unwise and unsafe and in the mojave Beta (wwdc/developer) it does not work for me.

        Solution: display the DeDRM program (script) in finder, right-click with your pointer (mouse or whatever) and chose open – this is also called CTRL-click .
        A question should pop up wether you want to run this unsafe program (“Are you sure you want to open it?” open/cancel with cancel selected).
        For mojave here is a link, which I just found and DID NOT test, but may well use (running a Beta is risky anyways), use at your own risk:
        https://www.tekrevue.com/tip/gatekeeper-macos-sierra/

      • Speaking of GitHub, I hope ApprenticeHarper is working on moving this project off GiTHub to an independent location.
