Extract audio
Get the audio out of any video you own
Need just the sound from a clip you filmed or recorded — a lecture, an interview, a voice memo, a song you made? This tool reads the audio track straight out of your video file and hands it back as a clean MP3, M4A or WAV. It runs entirely in your browser using WebAssembly, so your file never leaves your device.
How to extract audio
Click Choose a video and pick a file from your device, select your audio format (MP3 is the most compatible), then press Extract audio. The tool loads a small engine the first time, converts everything locally, and gives you an audio preview. When it's ready, download it — no account, no upload.
Private by design
Because extraction happens on your device, your video and its audio are never sent anywhere and nothing is stored. It works on desktop and modern mobile browsers — the first run downloads the engine once, then later runs are instant.
