Video2Mp3 is a free online service that lets you download Youtube videos after extracting the music file from it so that you an listen to your favorite YouTube tracks on every MP3 player.. This helps it reduce the size by at least 60%. For example a 6Mb video song will most probably be converted to 1.5MB or may be less.
All you have to do is copy the url of any Youtube video you want to download and click Convert.Â You can choose the quality of this track by choosing between “Stand Quality” and “High Quality”. If you have a high speed internet I would highly reommend that you choose the “High Quality” to enjoy better quality of the music.
In addition to all that it offers a Firefox add-on . The addon adds a link on YouTube Video pages to this service and converts the video directly.
