How this works
Your WAV file is decoded and re-encoded to MP3 entirely in your browser, using a lightweight, well-established MP3 encoder — no upload, no waiting on a server.
Which quality should I choose?
128 kbps is a solid, standard default that most people can't distinguish from the original for everyday listening. Choose 96 kbps for the smallest file when size matters most, or 192 kbps when you want the closest match to the original quality.
