How it works

1

Drop your video file

It stays on your device — nothing is uploaded.

2

Audio extracted locally

The MP3 track is extracted right in your browser via WebAssembly — the video stream is skipped, so it's fast.

One extractor for every video format

Screen recordings land as WebM or MKV, phone footage as MP4 or MOV, old archives as AVI or WMV — but "I just need the audio" is the same job in every case. This tool reads virtually any video container and codec and writes a clean MP3, M4A, or WAV, without you having to know or care what is inside the file.

Because everything runs locally in your browser, there is no per-file upload wait and no server queue: a video that would take minutes to upload converts in seconds on your own machine, and nothing is ever sent anywhere.

Frequently asked questions

Which video formats are supported?

Practically all of them: MP4, MOV, MKV, WebM, AVI, WMV, FLV, 3GP, MTS and more. The extractor is built on FFmpeg, the same engine professional tools use, running in your browser via WebAssembly.

How long does it take?

Usually well under a minute. Only the audio track is decoded and re-encoded — the video stream is skipped entirely, so even long videos process quickly right in your browser.

Will the audio quality suffer?

The audio is extracted directly from the video file, so you get exactly what the video contains. MP3 and M4A re-encode at a high bitrate that is indistinguishable for speech and music; WAV is fully uncompressed.

Can I extract only part of the audio?

This page extracts the full track. If you only need a section, use our video trimmer first — it can cut a range and export it directly as MP3 in one step.

Is it really free?

Yes. The audio extractor is completely free, with no signup, watermarks, or limits. We make money from our video translation service, not from this tool.

Do you upload my files?

No. The extraction happens locally in your browser using WebAssembly. Your file never leaves your device — you can even disconnect from the internet once the page has loaded.
