Free YouTube Download is an extremely comprehensive tool for downloading YouTube videos.
You can use the program just like many similar utilities, then, pasting the link of an individual video, then downloading it at a click. But that's just the start. You're also able to download all the videos from a selected YouTube user or channel, all the responses to a particular video, all the videos from YouTube charts, complete YouTube playlists, and more.
Free YouTube Download also understands the various video quality options which YouTube makes available, and can grab whatever file resolution you might require.
And if you can't play the FLV files used for lower resolution videos, then that's not a problem: in a click or two you can have Free YouTube Download convert your downloads to AVI or MP4 files, in either high quality or more compact "economy" versions.
Please note, the program will by default install the Ask Toolbar, as well as changing your browser home page and search provider. If you don't want this, be sure to choose the appropriate options during setup.
