Y2mate is good cloud-based YouTube downloader that supports famous file formats like MP4, M4V, 3GP, WMV, FLV, MO, MP3, WEBM, etc. High speed downloads without registration. I Like the way it downloads the videos directly on the web browser by Inserting "pp" after the word "youtube" in the link to download videos and mp3 files.
