I'm no expert, but this is sufficient for producing a KDF on my system. CDing to the right folder simplifies the invocation. No environment variables need presetting.

cd /Applications/Kindle\ Previewer\ 3.app/Contents/MacOS/lib/fc/

./jre/bin/java -Dfile.encoding=UTF8 -cp lib/EpubToKFXConverter-1.0.jar:lib/* com.amazon.kfxconverter.app.KFXGenApp -libDir . -tmpDir ~/Desktop/kdftest -outDir ~/Desktop/kdftest -inputFile ~/Desktop/test.epub -locale en -amzncreator "Kindle Previewer 3.1.0"

I have it to saving to my desktop for my own convenience.

Thanks. That is equivalent to what I am already doing. Something seems to be going wrong when invoking it via python in calibre.

Perhaps if I launch a shell and run the command that way it might work better. I will try that in a future release.

I have converted EPUB files to KFX successfully and transferred it to my kindle paperwhite 2, thanks.

I noticed that I cannot highlight text in converted kfx books nor does the device (Paperwhite 2) display page numbers, only location numbers.
Anyway, thank you for your efforts.

The missing page numbers are caused by the Kindle Previewer ignoring page numbers in the source EPUB. I tried it with EPUBs containing either an NCX pagelist or a page-map.xml and in both cases no page number information is produced by the Previewer. There is nothing I can do to fix this.

I can verify that attempting to highlight text in a sideloaded KFX does not work on my Paperwhite either. Internally the app crashes with "cvm[4145]: java.lang.NullPointerException: match". This is most likely due to something wrong in the KFX file produced by the plugin. I will try to fix it, but since KFX is undocumented it is a trial and error process.

Version 1.1.2 - 08 Apr 2016

Fix inability to highlight text in converted books on Kindle devices.

Assure author names are in the correct format for sorting.


(This release also contains another attempt to make the plugin work from within calibre under Mac OS. It would be helpful if a Mac user would try it again with this book and report back.)

Now working on Mac OS. No need for further reports.

Thank you, the plugin works very well for now. You're the best!!

Converted fine on my Macbook great thanks

[jhowell]

Thanks for the feedback.

I will wait a little and if no one reports a problem using the latest release under Mac OS within calibre I will update the documentation to remove the notes about the plugin not working properly with that OS.

It also worked with the test book on my Mac. Thank you!

Test book converted successfully on my Mac as well. Congrats on the nifty plug-in, jhowell!!

1.1.2 works great on my Mac too ��

[amordechai]

It works on my mac. Congratulations and thank you!!

[jhowell]

Thanks to all who tested. No need for further reports unless something needs fixing.

I tried to convert a big Epub-book (science fiction series Perry Rhodan, 124 mb) into the KFX-format and got the following error. System is a Core i7 with 16 gigs of ram and more than 60 gigs of space left on the HD.
I would like to cnovert it for my new Kindle Oasis.

Any idea, what I can do? I installed the lates previewer 3.1 beta today from Amazon.

Error-message:
calibre, version 2.56.0
FEHLER: KFX conversion failed: <p><b>Kindle Previewer error:</b> Exception in thread "main" java.lang.OutOfMemoryError: Java heap space

Thanks in advance.
