About WAV to MP3

Convert big uncompressed WAV files into compact MP3s that are a fraction of the size. Pick a bitrate and we transcode with ffmpeg.wasm — ideal for sharing recordings that would otherwise be too large to send.

The conversion runs locally in your browser. Your WAV file never leaves your device, so even unreleased recordings stay private.
