## Frequently asked questions

### Why WAV instead of MP3?

WAV is uncompressed PCM audio — the format audio editors, DAWs, and many transcription and speech tools prefer, because there is no lossy re-encode and no decoder quirks. If you plan to edit, process, or analyze the audio, WAV avoids adding a second generation of compression.

### How big will the WAV be?

Roughly 10 MB per minute of stereo audio (16-bit, 44.1 kHz) — noticeably larger than MP3 or M4A. If you just want to listen or share, MP3 is the better pick; the format switch is one click on this page.

### How long does it take?

Usually well under a minute. Only the audio track is decoded and re-encoded — the video stream is skipped entirely, so even long videos process quickly right in your browser.

### Is it really free?

Yes. The audio extractor is completely free, with no signup, watermarks, or limits. We make money from our video translation service, not from this tool.

### Do you upload my files?

No. The extraction happens locally in your browser using WebAssembly. Your file never leaves your device — you can even disconnect from the internet once the page has loaded.
