There are tons of tools to download regular YouTube videos but very few that let you enjoy the HD quality videos on your desktop. One great tool that lets you do this is KeepHD ^[1].

Using KeepHD, you can download your favorite HD movies in MP4 and FLV format and also download the mobile 3GP version for your mobile devices. So now you can enjoy HD quality movies while you are on the go. There are two simple ways to use KeepHD. You can either go to www.KeepHD.com and enter the URL of the video to start downloading.
