About Video to Audio Extractor
Last updated: June 2026
OptiPix Video to Audio Extractor pulls the audio track from any video file directly in your browser. Upload MP4, WebM, MOV, AVI, or MKV videos and extract the audio in your choice of format: MP3, WAV, OGG, FLAC, AAC, or OPUS. Control bitrate for lossy formats. The tool uses FFmpeg.wasm with the -vn flag to discard the video stream and encode only the audio. Processing happens entirely on your device - your videos are never uploaded anywhere.
How It Works
The tool uses FFmpeg.wasm with the -vn flag to strip the video stream, then encodes the audio track in your chosen format and bitrate. The entire process runs locally in your browser.
