A free video file converter?

I'm looking for a free video file converter so I can convert some avi.file movies so they are able to be watched on my iphone and ipad which I think means it has to be mp4? Anyway whenever I install something it either watermarks, or says the file is to large to be converted and then tells me to buy a full version or something but I don't want to pay any money. If anyone has any TRUSTED FREE file converters please answer As soon as possible!
