Best video converter to iphone format

Im looking for a decent free video converter to convert stuff to iphone compatible format. I've randomly tried one but the ads where huge and annoying so im after something functional but with no ad's preferably.

There seems to be tons listed in google and no idea which to go for.

Thanks for any help you can provide.

 

Try Format Factory

It works great converting to/from lots of different formats, has a joiner, and is extremely fast.

 

Thanks will try it out now!

 

Any Video Converter is really good too.

 

I use SUPER © for all my converting needs.
