Frequently asked questions
Is my video uploaded to extract the audio?
No. The conversion runs in your browser with ffmpeg.wasm, so the file never leaves your device. Nothing is uploaded to a server.
Which audio formats can I export?
You can save the audio as MP3, M4A (AAC), WAV (PCM) or Opus. Pick the one you need from the Format dropdown before extracting.
Can I extract only part of the video?
Yes. Enter a Start time and a Length in seconds to trim the output to just that section; leave Length blank to grab everything from the start point on.
Why does the first run download something?
The audio engine (ffmpeg.wasm, around 31 MB) is fetched once on first use, then reused. After that, extractions start faster.
