In a recent communication, Amazon has alerted Kindle users about significant changes set to take effect from next month. The notification pertains to the phasing out of support for sending MOBI (.mobi, .azw, .prc) files through the “Send to Kindle” feature, starting November 1, 2023. This change, as News18 pointed out, specifically impacts users attempting to send MOBI files via email and Kindle apps on iOS, Android, Windows, and Mac.
Calibre + KFX plugin. That’s it.
KFX supports hyphenation and many more advanced features - the plugin exploits the official Amazon app for publishers to convert any open format into KFX, giving you all the features of Amazon store bought books for free.
Calibre has been a life saver for me. Love that program!
Is this the plugin?

Yes!
Sadly, KFX plugin does not work in Linux (it lacks Kindle Preview app)
How about using Bottles ?
Been meaning to, but havent try yet.
Still bit a noob, I am wondering if I should also install calibre through bottles (I imagine bottles sets up some sort of sandbox that only those installed through it can use its files).
Why are kfx files often larger and sometimes double the size?
Lacks compression?
Don’t know if it really matters, though. 8GB of storage holds a lot of books, even if they’re illustrated, and that’s what base-model e-readers are coming with.
It matters to me, since I find the differences in sizes to be stark when I compare them. I already find page turns on my Paperwhite a tad slow (even with page refresh off). So converting all of my books to kfx (which was my initial plan) seems like a bad idea.
KFX is actually faster at page turning, as it doesn’t need to calculate how to spread words to fill the most lines per page.
That makes sense to me. Access speed and disc space are often inversely related. It’s like pre-optimizing the file for faster consumptionater by adding more information at “compile time” vs “run time”.
A source to read more about this and how exactly kfx works and it’s enhanced typesetting would be cool.
Do you know of alternative methods of producing kfx files other than the official Amazon app and Calibre’s plugins for it?
And how would I go about editing a kfx file?
I’ll have to try that KfX plugin. I also read somewhere someone was listing a stack he was using with Calibre but I can’t find it anymore…
