I haven’t used Kindles personally ever, but I helped my neighbor export their kindle collection a few years ago.

It dumped it into mobi files to use with calibre. Then from there, you can convert them into epubs.

I recall it being straightforward. Probably something a kindle owner should do periodically to back up their collection.

It’s absolutely frustrating.

The “Guys you really shouldn’t punch a Nazi they’re just misunderstood UwU” assholes online really never had to deal with these racist hateful mofos.
