How It Works
A step-by-step look under the hood
Step 01
File is read locally
Your video is loaded using the browser's built-in File API — it stays on your device, zero bytes sent anywhere.
Step 02
Video is decoded
The browser parses the video container (MP4, MKV, etc.) and demuxes it to separate the audio track.
Step 03
Audio is encoded
The raw audio data is re-encoded to your chosen format (MP3, WAV, OGG…) at the selected bitrate.
Step 04
Download & preview
A download link is generated directly in your browser. Listen first, then save the file to your device.
