🎬 Video to Audio

How Video to Audio Extraction Works

This tool separates the audio track from a video file using FFmpeg compiled to WebAssembly. The entire extraction runs inside your browser - the video never leaves your device, and no server processing is involved.

Upload any video your browser can handle (MP4, WebM, MOV, MKV) and choose an output format: MP3 for maximum compatibility, or WAV for lossless quality.

Pro Tips

  • For music and podcasts, MP3 at default quality is the sweet spot between size and sound.
  • Large videos (over 500MB) may take a few minutes and significant memory - close other tabs first.
  • The first conversion loads the FFmpeg engine (~30MB). It stays cached in your browser for instant reuse.

Frequently Asked Questions

Is video to audio conversion really free?

Yes, completely free. No uploads, no accounts, no watermarks.

What video formats are supported?

MP4, WebM, MOV, MKV and anything else FFmpeg can decode.

Does converting lose audio quality?

Extract to WAV for lossless output. MP3 at default settings is transparent for most listeners.

Is my video uploaded to a server?

No - everything runs locally via WebAssembly. Your files never leave your device.

Why does the first conversion take longer?

The FFmpeg engine loads on first use (~30MB). After that, conversions are fast.
