[Conversion Plugin] KFX Input

[JSWolf]

Given you have Windows 11, you can remove the DRM. Just follow the link that @jhowell posted in this thread (this page) and go from there.

You will also need KFX Input.

I'm having a bit of an issue with the plugin, it doesn't seem to appear when I try to bulk convert my files (in the left-hand panel) and it doesn't do the conversion for KFX files in my library. It works fine for individual books, but I have over 400 KFX books, so if bulk converting was possible I'd obviously be very happy. Is there something I've missed, or does that not work with the plugin?

If I select multiple books with KFX format and bulk convert them it does it for me. What do you mean by “it doesn’t do the conversion”?

You can also try using the From KFX toolbar button. See the first post in this thread for details.

If I select just one book that's a KFX format, it converts it to epub without problem, and the left hand sidebar looks like the first picture.
If I select multiple books, whether they are all KFX or a mix of KFX and not, the sidebar looks like the second picture, and I get the error message I included in the third if I try to go through with it. The conversion doesn't happen.

I'll look into the toolbar but it seems like there's an issue somewhere (I'm sure I did something wrong, I just don't know what) that makes the plugin malfunction with the bulk command.

That is normal. It is just how calibre works.

That error can appear if a KFX book file is imported incorrectly from a kindle app. For example the Kindle for PC/Windows app uses a file extension of .azw regardless of the book’s actual format. If that is imported improperly it will show up in calibre as AZW instead of KFX, resulting in that error if you attempt to convert it.

Ah, thank you! I will try to import my collection again and see if that solves it then.
