The fastest WAV to MP3 conversion on macOS

macOS doesn't include a built-in WAV-to-MP3 converter. iTunes/Music can do it but requires importing the file first. This browser tool decodes WAV and encodes MP3 locally using the Web Audio API — faster and more private than any upload-based alternative.
