Any tips for extracting images from pdf files?

There are a lot of achives of comics here and on other websites with pdf files containing regular old images of comics.
Does anybody here know good, open source, safe and exclusively offline tools to unpack images from pdf files?
The ones I'm interested in only contain images, but even the few that have text in them desperately need to be unpacked too and I'd rather lose the text in those, if it means that I can just view the image files separately.
I found a couple of things in Google but they all look dodgy. No thanks. I'd prefer recommendations / reviews from real people first.

Looks like there is a PDF to JPG converter by " TriSun Software". Haven't tried it myself but looks like it is free and will do what you want.
