WAV to FLAC

Compress a WAV file to FLAC without losing any audio quality. FLAC files are typically 40–60% smaller than the equivalent WAV and decode bit-perfect, making it the go-to format for archiving and high-quality libraries. Conversion runs entirely in your browser using ffmpeg.wasm — nothing is uploaded. Expect a few seconds for a 5-minute song; longer files may take a minute or two.
