About this tool

Convert audio files locally in your browser — nothing is uploaded.

  • Input — WAV, MP3, FLAC, Opus, OGG, M4A/AAC, AIFF, ALAC (whatever your browser can decode).
  • Output — WAV, AIFF, MP3, Opus (WebM/OGG), AAC/M4A when supported.
  • Adjust bitrate, and mix down to mono or left/right channel.

MP3 encoding loads a small encoder script on first use. FLAC and ALAC can be opened as input but are exported as PCM (WAV/AIFF) or lossy formats.
