A few things worth knowing before you process.
Is it free, and are my files uploaded?
Completely free with no signup and no processing limits — everything runs locally in your browser, so there's no server cost to pass on. Extraction and separation happen entirely on your device, and the video is never uploaded.
What's the difference between the three outputs?
Full track is the original soundtrack; voice-only is the speech/vocals with music stripped by AI; music-only is the soundtrack with the voice removed. All export as 192kbps MP3.
What formats and limits apply?
Common video formats like MP4, MOV and WebM, up to 500MB and 10 minutes per file.
Can I use the extracted audio commercially?
The tool doesn't change who owns the material. Make sure you hold the rights to the source video and follow the original creator's and platform's terms.
How long does processing take?
Full track takes seconds. Voice-only or music-only runs a local AI model: the first run downloads ~45 MB once, then expect seconds to tens of seconds per minute of footage.
