Video to Audio
Extract the audio track from a video as MP3, WAV or M4A, without uploading it.
What it does
Video to Audio works on MP4, MOV, WEBM, MKV, AVI and M4A with ffmpeg and audio engines compiled for the browser, so the recording or video is processed by your own computer or phone — the same programs a desktop editor uses, without installing one.
When you need it
Usually right before sending or publishing: a video too heavy for WhatsApp, a voice note full of hum, a clip that needs captions because the feed plays it muted, an interview to turn into text.
Limits and caveats
Long or high-resolution files take as long as your device needs, and a phone is slower than a laptop. The engines download once, the first time, and come from KIVO itself. The original file is never changed: you always download a new one. Everything happens in your browser, so the file never leaves your device.
How to video to audio
- Drop the video.
- Pick MP3, WAV or M4A.
- Download the audio.
Everything happens on this device: no file is uploaded and nothing leaves the browser.
Frequently asked questions
- Does the quality drop?
- MP3 and M4A re-encode, so slightly — both are set to a transparent bitrate. WAV does not re-encode at all, and is much larger for it.
- Can I take audio off a video site?
- No. This works on a file you already have. It has no way to fetch anything, which is the same reason nothing you drop on it gets sent anywhere.
- Do my files get uploaded?
- No. This tool runs entirely in your browser, so the file never leaves your device.
