About muting
This tool removes the audio track without re-encoding the video. It's nearly instant even on large files, because no pixels are touched — we just drop the audio stream and re-mux the container.
FAQ
Does the file get uploaded anywhere?
No. Open this page, turn off your wifi, then try a file — it still works. That's the test.
What's the maximum file size?
Browser memory is the limit. WebAssembly caps at 2–4 GB per file. Most laptops handle 1080p videos under a gigabyte comfortably.
Why is it slow on my phone?
FFmpeg-WASM runs on your CPU, not hardware video encoders. Phones have less CPU, so encoding takes longer.
Can I cancel mid-encode?
Yes. The Cancel button terminates the worker immediately. You'll wait a few seconds the next time you start.
