Youtube.com and most of the video sharing websites do not allow you to download videos. However these two sites make up for that lack.

1) KissYouTube.com image

  • You can download any video hosted on youtube. Just enter the full URL in the text box on home page.
  • Other way is to append the word kiss before youtube in your URL Ex: Eg. http://www.kissyoutube.com/watch?v=tRTk0RPXtW4

Kiss you tube does not work for other sites like Google Videos. For these sites you can use

2) http://keepvid.com/ image Works the same way as 1)
