Converting from Spotify or YouTube?

This hub converts files you already have. To convert from a streaming link instead, use the Spotify & YouTube converter on the homepage, or the YouTube to MP3 320kbps tool. Need a smaller MP3? Use the MP3 compressor.

A Note on Quality

Converting to MP3 preserves the source; it can't improve it. A high bitrate (320 kbps) keeps a good source transparent; a low one trades quality for size. And extracting audio from a video is capped by the video's own audio bitrate. For the full breakdown, see the MP3 bitrate guide and is MP3 lossless?
