● Your video is processed locally in your browser and never uploaded. Large files need a recent computer with enough memory.
How it works
Your browser decodes the video's audio track directly (no video decoding needed, so it's fast), then the sound is encoded to MP3 with the LAME encoder or saved as WAV. If your browser can't read the video's audio codec, the tool falls back to the ffmpeg engine automatically.
