Extract Audio
Extract Audio pulls the soundtrack out of a video and saves it as an audio file — MP3, WAV, M4A or OGG. It's the quickest way to grab the music, dialogue or sound from a clip without the picture. The whole thing runs in your browser with FFmpeg, so your video is never uploaded.

The file is read by your browser and stays on your device — there is no upload step.

What do you actually need out of it?
Pulling the sound out of a video is one of the most common jobs on this site, and one of the easiest to over-complicate.

What you will get back
- The original track, copiedbest quality
Where the format allows, the audio stream is copied out of the container untouched — no re-encoding, so nothing is lost.
- Or re-encoded to MP3most compatible
Where you need a specific format, the track is re-encoded once. Starting from video audio that was already compressed, keep the bitrate reasonably high to avoid stacking losses.
- As good as the source
Video soundtracks are already compressed, often at modest bitrates. Extraction cannot recover what the camera or the platform discarded.

Your file, and what the page does
Your file is never uploaded. Extract Audio reads it into this browser tab and processes it with FFmpeg compiled to WebAssembly on your own device. There is no upload endpoint in the application and no copy on any server — closing the tab discards it.
That is also why processing takes longer here than on a site that uploads: your device is doing the work rather than a rack of servers. The trade is that the file never leaves it.
What the page does send or fetch
- The processing engine, once
- The first time you use any video or audio tool, the browser downloads the FFmpeg WebAssembly build (~30MB) from the jsDelivr CDN and reuses the cached copy afterwards. That is a file coming to you — no part of your own file is in the request.
- Ads on the page
- The site is funded by advertising, so the page loads Google AdSense. That carries the usual web basics — IP address, browser, referring page — as on any ad-supported site.
- An anonymous usage counter
- When Extract Audio finishes we record that the tool ran, whether it succeeded and how long it took. No file data, no identifier, no cookie.
Your file is not on that list. How this works.
Frequently asked questions
MP3 is small and plays everywhere. Choose WAV for uncompressed, lossless audio, or M4A/OGG when a specific app needs them.
Extracting to WAV is lossless. MP3, M4A and OGG re-encode at a high 192 kbps bitrate, which is transparent for most material.
Any video with an audio track works — MP4, MOV, WEBM, MKV and more. A silent video has nothing to extract.
Yes — Extract Audio is completely free. There's no account, sign-up, watermark or limit.
No. It runs in any modern browser — Chrome, Edge, Safari, Firefox, Brave — with nothing to download or install.
