Windows 7 Tip: 
Last year, I reviewed the Movavi Online Video Converter and Media-Convert which allows you to Convert Video Online, But there is one more new Online Video Converter Viloader. Viloader help you to Convert Any Video Format to Any other Format Free. You Can Also Convert the Youtube, Metacafe, Dailymotion Video there. For this you have to enter the Url of the Video and Choose the Format that you want to save in your Computer.
From this site you will be able to convert videos online:
1.- Select the source ( Url or Browse File )
2.- Choose Input and Output
3.- Click convert button
Good, thanks for the information.
