Com funciona

Pulling the audio track out of a video normally means an upload to some conversion site. Here the real FFmpeg encoder runs in your browser, so the video never leaves your device.

1
FFmpeg.wasm loads once
The WebAssembly build of FFmpeg (~30 MB) downloads on first use and is then cached for instant reuse.
2
You choose a format and bitrate
Your file is loaded into FFmpeg's in-memory filesystem. The video stream is dropped (-vn) and only the audio is kept.
3
FFmpeg re-encodes the audio
MP3 (libmp3lame), AAC, or lossless WAV (PCM) — the same encoders used by desktop FFmpeg, running locally on your CPU.
4
The audio file is offered for download
The result is handed back as a downloadable blob and can be previewed with the built-in player.

No upload, no queue, no file-size cap. Your video and its audio stay entirely on your device — safe for interviews, lectures, music, or any private recording.
