YouTube videos can be downloaded in various different formats . For example your favorite music video is on Youtube but you only need the song so you extract the audio from that Youtube video without even downloading the video . For this purpose I recommend you visit Vixy.net .
The above site downloads the online Youtube video file on its server and has the ability to convert YouTube videos into the following formats :
- 3GP for mobile
- MP3 audio only
You just have to give the URL of the YouTube video and it will do the rest . Cool isn’t it .
