More free audio tools
Same quality bar. Still free. Still no upload.
Your files never leave your device
Free to use, with no account, no usage limit and no watermark, because the work runs on your device rather than on our servers.
This is not a promise about how carefully we handle your upload. There is no upload. The file you choose is read into memory by your own browser, processed there, and handed back as a download — the tool has no server component and makes no network request with your data.
- Nothing is stored. We never receive the file, so there is no copy to retain, no retention period to disclose, and nothing to delete on request.
- Nothing is transmitted. No upload endpoint, no analytics payload carrying file contents, no third-party processor.
- You can verify it. Load this page, disconnect from the internet, and use the tool. It still works, because everything it needs is already on your machine.
- Nothing persists after you close the tab. Files are held in page memory only — not in local storage, not in a cache, not in a database.
A note on wording, because it matters: we do not describe these tools as “encrypted.” Encryption protects data that travels to somebody else's computer. Your file does not travel, so there is nothing to encrypt and nothing to intercept — which is a stronger guarantee than encryption, not a weaker one. The page itself is served over HTTPS like the rest of the site.
This makes the tools safe for material you are contractually barred from uploading to third-party services — client footage under NDA, unreleased campaign assets, anything covered by a confidentiality clause.
How it works
1. Drop the video
Choose an MP4, MOV, WebM or other clip your browser can play. The file is read into local memory only.
2. Check the details
The page decodes the sound and shows its channels, sample rate and length so you can confirm it is the right file. There is no playback preview. A clip with no sound track is reported as an error.
3. Download WAV
Export uncompressed WAV for editors, loudness meters, or caption workflows that want clean speech.
Questions
What does a free audio extractor do?
It pulls the audio stream out of a video file and gives you a downloadable WAV, entirely in your browser, so you can edit or transcribe speech without uploading the clip.
Can I extract audio from a video as MP3?
Not directly: this tool downloads WAV. WAV is uncompressed and widely accepted by editors, loudness tools and speech pipelines, and re-encoding to MP3 would add another lossy pass on top of whatever the video already applied. WAV files are large, roughly 10 to 12 MB a minute for stereo, so convert the WAV to MP3 in your audio editor if size matters.
Will this work offline?
Yes, once the page is loaded. Decoding and export use browser APIs on your machine, so a disconnected network does not stop the extract.
How big a video can I extract audio from?
Videos up to 1 GB and 20 minutes, and audio files up to 80 MB. The whole file is read into your browser's memory to decode the sound, so on a phone keep videos to a few hundred MB. The WAV keeps the source's sample rate.

Everything on this page works on a file you already have, which is why it costs nothing. Generating something that did not exist (video from a prompt, a voice, a score) runs a model, and that costs credits.
