Mute an MP4 video
Drop an MP4 and get back the same video with the audio track removed. The video stream is copied without re-encoding, so quality is unchanged and the conversion is fast. Your file never leaves your device.
About muting a video
Removing the audio track is useful when you need a silent version of a clip — for a background loop, a video to overlay your own narration onto, or to satisfy an upload requirement that prohibits copyrighted audio. This tool uses stream-copy for the video: the video data is passed through without decoding or re-encoding, which means no quality degradation and near-instant processing even for large files.
Is it private?
Yes. The converter is WebAssembly and browser APIs running on your own machine. Nothing is uploaded, stored, or seen by us — there is no server to send files to.
Frequently asked questions
- Does muting the video reduce its quality?
- No. The video stream is copied through without decoding or re-encoding, so the picture is unchanged. Only the audio track is removed.
- Are my files uploaded to a server?
- No. The processing runs on your device using WebAssembly and browser APIs. Your video is never sent anywhere, and the tool keeps working even if you go offline after the page loads.
- Is it free, and do I need an account?
- It is free with no watermarks, no daily caps, and no sign-up. Drop a file, mute it, and download the result.
- Why is muting so fast even for large videos?
- Because the video data is stream-copied rather than re-encoded. There is no frame-by-frame decoding step, so processing is near-instant even for large files.
