XoA YouTube Video Tools first started as an audio extractor for YouTube videos, it now has been updated to include video conversion as well using the backend of ffmpeg.
Download and save your favourite YouTube Video by entering the URL into XoA YouTube Video Tools. Select the downloaded video within XoA and either extract just the audio out of the file using our fast audio extracting processor or convert the file to mpeg to be played on any media player that supports MPEG extension. (Uses FFMPEG backend)
