A free, private tool that pulls the soundtrack out of a video file and saves it as MP3 or WAV — entirely in your browser. Drop in an MP4, MOV, WebM or MKV, choose the output format and quality, and the video track is discarded while the audio is re-encoded on your device using the browser's built-in codecs. Nothing is uploaded and no account is needed. It's the quickest way to turn a recorded lecture, meeting or clip into an audio file — and the natural first step before transcribing a video with the Speech to text tool.
How to use Extract audio from video
- Load a video — Drop the file onto the tool or click to choose it. A preview player confirms it's the right clip.
- Choose the output — Pick MP3 (with 128, 192 or 320 kbps quality) for small shareable files, or WAV for lossless audio.
- Extract — Click Extract audio and watch the progress bar — long videos take a little while, all processed locally.
- Listen and download — Preview the result in the built-in player, then download the audio file.
Frequently asked questions
Is my video uploaded to a server?
No. The file is demuxed and the audio re-encoded entirely inside your browser using WebCodecs — it works offline.
Which video formats are supported?
MP4, MOV, WebM and MKV containers. The audio inside must be a codec your browser can decode — AAC, Opus, Vorbis, MP3 and PCM all work in modern browsers.
Can I get a transcript of the video?
Yes — extract the audio here, then open the file in the Speech to text tool, which transcribes it on your device with the same privacy.
MP3 or WAV — which should I pick?
MP3 at 192 kbps is right for almost everything. Choose WAV only if you plan to edit the audio further and want to avoid a lossy step.
Tips
- For voice content, 128 kbps MP3 is usually indistinguishable from the original and keeps files small.
- Extracting audio needs a reasonably recent browser — Chrome, Edge or Safari have the best WebCodecs support.
- Trim the result afterwards with the Audio trimmer if you only need a section.
