Come funziona
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.
- 1FFmpeg.wasm loads onceThe WebAssembly build of FFmpeg (~30 MB) downloads on first use and is then cached for instant reuse.
- 2You choose a format and bitrateYour file is loaded into FFmpeg's in-memory filesystem. The video stream is dropped (-vn) and only the audio is kept.
- 3FFmpeg re-encodes the audioMP3 (libmp3lame), AAC, or lossless WAV (PCM) — the same encoders used by desktop FFmpeg, running locally on your CPU.
- 4The audio file is offered for downloadThe 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.
