Secondly, the conversion is fast and usually takes one or two seconds. And then, you are offered choices as to download, save to Dropbox, or continue to convert the next video. You can also choose to download your video as either MP3 or MP4.

YTMP3 claims to auto-convert YouTube to MP3 in the highest quality available. But we found that it can only convert audio to half of the original audio quality. (We tested it with an MP3 320kbps song, and the converted result is in 192kbps). If you have high-demand for the audio quality, this site may not be the best choice for you.
