How to extract audio from a video
- Open a video file from your device — the track is decoded locally.
- Wait for the file to load; long videos take a few seconds to analyze.
- Start the extraction and watch the live progress bar.
- Download the resulting WAV file when the progress finishes.
Frequently Asked Questions
Which video formats are supported?
Videos the browser can play, such as MP4, WebM, and MOV.
How long does extraction take?
It processes in real time relative to the video length, roughly equal to the video duration.
What format is exported?
Standard WAV (PCM), with selectable sample rates of 16000 / 44100 / 48000 Hz.
Is the video uploaded?
No. The video is decoded locally in your browser — it never leaves your device.
Why is the output WAV instead of MP3?
WAV is the uncompressed digital audio the decoder already produces, so no extra quality is lost in a second encoding step. Convert it to a compressed format afterwards if you need a smaller file.
Is my video file uploaded?
No. Decoding and extraction run locally in your browser using Web Audio; the file never leaves your device.
