How it works
Drop in a clip and it is read straight from disk with the File API — nothing is uploaded, so home videos, screen recordings and phone footage never leave your device. The preview plays muted immediately, so you can check you picked the right file before exporting anything.
Mute video then plays the clip once while the picture is captured from a canvas and written into a new WebM file by the browser's built-in MediaRecorder — the audio is simply never attached, which is why the result is genuinely silent rather than just turned down. Choose remove the audio track completely for the smallest file, or keep a silent audio track when a player or upload target insists on one. Because the clip is re-recorded in real time, a 30-second video takes about 30 seconds; leave the tab in the foreground while it runs. WebM plays in Chrome, Edge, Firefox and Safari 14+; drop it into your editor if you need MP4.
Frequently asked questions
How do I mute a video online?
Drop your MP4, WebM or MOV file onto the box above, leave "Remove the audio track completely" selected and press Mute video. The clip is played through once while the picture is captured into a new file, then you can preview the silent result and download it. Nothing is uploaded: the file is read straight from your disk with the File API and re-recorded inside this page, so private recordings never leave your device and the tool keeps working even with your Wi-Fi off.
Is the sound removed for good, or just turned down?
It is removed for good. The exported file is built from the video frames only — the audio is never attached to the recording, so there is no hidden track anyone can turn back up. If you pick "Keep a silent audio track" instead, the export does contain an audio track, but it is generated as pure digital silence by the Web Audio API; that option exists because some players, editors and upload targets misbehave with a video that has no audio stream at all.
What format does the muted video come out as, and is there a watermark?
A WebM file (VP9 or VP8, depending on your browser), which plays in Chrome, Edge, Firefox and Safari 14+ and uploads fine to YouTube, Discord and most editors — import it into your editor if you specifically need MP4. There is no watermark, no sign-up, no length or resolution cap and no ads. Because the browser's built-in MediaRecorder re-records in real time, a 30-second clip takes roughly 30 seconds to mute; keep the tab in the foreground while it runs, and use the Maximum width option if you also want a smaller file.
