web searches suck

i was looking for something i needed to change some video's i have on my website from one format to another, and do you think i could find one that was free? i sure could! but i had to pay for it first...
now i know it sounds stupid, but i entered "free 3gp video converter" and all i got was this, this none of them are free, free trial maybe but i wasnt looking for free trials, if i was id have put trial in the search
