I guess I won't waste my time doing so again.

With permission from Satsuoni, I started using a python script as a wrapper for K4PC (since Jul 2025) and eventually also for MSIX and Android Kindle app versions.

Now I have merged them into a single app (spares user having to install python), makes it much easier to maintain (for me) and allows me to help other users troubleshoot when they can't get Satsuoni's tools working in their setups.

It may not be as fancy as what Epubor may provide but is functional for non-techy users and there is no fee to use it.

I made this ultimately for me as a one click, Extractor + Import (To Calibre) + Convert (Using Calibre and KFX-Input plugin).

This is overkill for sure, 100% not needed, but some may find it useful.

What ppl may not like:

• Needs registration on blog (free, no ads, no mailing list, no contact from me, not selling email addresses) (This prevents unwanted bots scraping the site, specially for Amazon related content and reduces Hot-Linking ).
• Uses email to activate app (App talks to my server and allows to serve the correct Satsuoni extractor needed by the user, as well as provide updated extractor when released, also missing DLL's when needed for Fallback)

This should work? But I do feel that it is less stable than before.

Hi there! I just tried importing De_DRM.zip with the "load plugin from file" option in Calibre and it didn't work.

calibre, version 9.15.0
ERROR: Unhandled exception: <b>InvalidPlugin</b>:The plugin in 'C:\\Users\\XXX\\Downloads\\DeDRM_tools.zip' is invalid. It does not contain a top-level __init__.py file

Am I doing something wrong?

I was so happy about this, registered to your site, read it all... only to realise I have Win 10 with no TPM available on my motherboard. Is all hope lost for me?

install win 11 in a virtual machine

I believe Legacy Kindle for PC 2.9.1 is still working, and Jadehawk's app can handle that as well.

It has been quite a while since I've purchased anything from Amazon (due to their increasingly abusive behavior to customer, and now to authors), but I do occasionally grab free books. Over time, importing them into calibre has become harder and harder until it just stopped working with with win10 and old k4pc. While I've kept up with the DeDRM stuff and knew that if I really wanted to, I could probably convert one that I really cared about, the complexity was such as I was not willing to put in the effort.

Even though the directions for your method was more than I felt like reading, it turned out that a quick scan and a halfhearted effort at installing the program and paying just enough attention to figure out where the kindle app was storing things was all it took. Very nice. I now have my backlog of free books ported into calibre.

While it may not be "needed", it was much appreciated. Thanks!
