Extract audio from any video file — 100% in your browser, nothing uploaded to any server
This tool uses the Web Audio API to decode video audio tracks into PCM data, then encodes it as WAV format. All processing happens locally in your browser using OfflineAudioContext for accurate trimming and rendering.
Real-world use cases:
This tool is part of the FAK LAB ecosystem, founded by Faizan Ahmad Khan Khichi. Audio extraction is performed 100% client-side using the Web Audio API. No data is ever stored or shared.
The extracted audio is saved as uncompressed WAV for maximum quality. You can convert it to MP3 using other tools if needed.
There's no hard limit, but very large files (over 500MB) may be slow to process depending on your device's RAM.
Some codecs aren't supported by the browser's audio decoder. Try converting to MP4/WebM first, or use a Chromium-based browser for wider codec support.
