Kindle to PDF/Word/other converter

Going to have a ton of down time due to some upcoming surgeries and would like to catch up on some reading. Have a ton of books on Kindle but the formatting options for that platform sucks.

Have downloaded a few "free" converters on to an old laptop to check them out but they also installed so much bloat/spy/malware that I'm going to have to reformat the drive to get rid of it all.

Willing to pay a few bucks if necessary for something that works without too much hassle. Whap program(s) have you used and recommend?

Thanks!

Are you trying to get books onto or off of the Kindle?

I use Calibre.

Not a converter, but I swear by Moon Plus Reader on Android for reading any and all formats.
The free version is great, but if you wait until he runs a sale, you can upgrade to the "Pro"
version for a buck or 3.

I receive nothing for endorsing this. Just an awesome underrated product that does exactly what it
says it does. Enjoy!
