Video to Audio Converter
Extract audio tracks from video directly in your browser using WebAssembly. Your files never leave your device – all processing happens locally.
How it works & privacy
1. Files never leave your device
The video is never uploaded or stored on any server. All conversion is executed via WebAssembly (ffmpeg.wasm) directly in your browser.
2. First run caches the converter
On the first run, your browser downloads the converter module (~30 MB from cdn.jsdelivr.net), which your browser usually keeps in its cache for next time.
3. Large files and mobile memory
Conversion runs in the browser's memory. Very large videos (roughly over 1.5 GB, or over 500 MB on a phone) may run out of memory. In that case, convert a shorter segment using trimming.
This tool is intended for converting your own recordings. Please respect copyright.
