Is Mute video free? Is there a watermark?

Yes — Mute video is free to use with no sign-up or watermark. Very large files can still be limited by your browser's available memory and processing resources.

Do my files get uploaded to a server?

No. Mute video runs entirely in your browser with WebAssembly, so your MP4, MOV, WebM, MKV file never leaves your device and nothing is stored or seen by us.

What can I put in, and what do I get out?

Mute video accepts MP4, MOV, WebM, MKV and gives you back a MP4 file. Actual codec support depends on what the bundled engine or browser decoder can read.

Does Mute video change my original file?

No. It never touches your original — Mute video creates a brand-new MP4 file to download and leaves the source on your device untouched.

Get a better result

Best for: Removing sound before a silent social post, presentation background, autoplay loop, or visual reference clip.
Input → output: The audio stream is removed while the original video stream is copied into an MP4 container, avoiding a new picture encode when muxing succeeds.
Quality tip: H.264 MP4 sources are safest because their copied video already fits the destination container. Play the result through to confirm timestamps and silence.
Know before running: WebM or MKV video codecs may not remux into MP4 cleanly. Muting does not redact visible information, captions burned into pixels, or metadata stored elsewhere.
Next step: Compress video if the silent asset also needs a smaller transfer size.
