"Perfectly Converts and is FREE (I'll explain)"
It can convert pdf's to EPUB, TEXT, Image, PDF (Password protected option). It works, it's free and it's fast. Each file conversion has its own options too. You can also do batch conversions. Really useful program.
You DO NOT have to upgrade to a paid version. All that happens is after each conversion a pop-up box comes up 'Asking' if you want to upgrade. Just click No.
It IS free but you are given the option to upgrade which you either go for or simply decline. It's great that pdf's can be converted into many formats using PDF Mate. It creates a folder where the conversions are stored but I am sure that you can change the output destination. Honestly this is Free :)
