Buying a video converter could be quite expensive although you would love the quality and speed some of this professional software can offer you.
From the list below you can choose a free video converter, which could be at help for most common video format conversions.
I used all of these myself and I think they are really efficient dispite the fact they are free, although you might experience one or two bugs and a few trials and errors to get the desired result.
Pay attention during installation that you don’t install any annoying toolbars!
It would be great if you would share your opinion on these or if you can add to the list.
