MP3 to OGG

Re-encode an MP3 file as Ogg Vorbis. Vorbis is a free, open audio codec that often sounds better than MP3 at lower bitrates. Because the source is already lossy, expect some quality loss in the re-encode — pick a higher quality setting if you care. The conversion runs entirely in your browser using ffmpeg.wasm; nothing is uploaded. Typically takes a few seconds for a 5-minute song; longer files may take a minute or two.
