🎵 Video to MP3 — Extract Audio

Pull the audio out of any video (MP4, MOV, WebM, MKV…) and save it as MP3, M4A or WAV. 100% in your browser — your video is never uploaded.

✓ Free Forever · ✓ No Signup · ✓ No Upload · ✓ Works Offline

🔒 Your video never leaves your browser. The audio is extracted on your device with FFmpeg compiled to WebAssembly — there is no upload, no account, and nothing is stored. Even big files stay private.

Features

  • MP3, M4A or WAV — Pull the soundtrack out of a video and save it as MP3, M4A (AAC) or lossless WAV.
  • Nothing uploaded — Runs entirely in your browser with FFmpeg.wasm — your video and audio never touch a server.
  • Choose the bitrate — Pick 128–320 kbps for MP3/M4A to balance quality and file size, or WAV for lossless.
  • No install, no sign-up — No app, no account, no watermark. Drop a video and get the audio.

  3. Extract & download — The audio is pulled out in your browser; preview it and download.

Frequently Asked Questions

How do I extract audio from a video for free?

Drop your video, choose MP3, M4A or WAV, and click Extract. The audio is pulled out in your browser and you can download it — no sign-up, no watermark.

Is my video uploaded to a server?

No. Extraction runs entirely in your browser using FFmpeg compiled to WebAssembly, so your video never leaves your device.

Which formats can I get — MP3, M4A, WAV?

All three. MP3 (libmp3lame) is the most compatible, M4A (AAC) is smaller at the same quality, and WAV is lossless.

What video files are supported?

MP4, MOV, WebM, MKV and AVI are supported, up to 500 MB.

Why does it take a moment the first time?

The audio engine (FFmpeg.wasm, ~30 MB) loads once on first use, then later extractions are fast.
