Video Mute

What it does

Drop a video in (MP4, WebM, MOV — any format your browser plays), get back the same video with the audio track removed. The picture quality, resolution, framerate, and duration are unchanged because the tool re-records the existing video stream rather than re-encoding it from scratch — so a 1080p H.264 input gives you a 1080p output (in WebM/VP8 container, since that's what browser MediaRecorder produces).

Common reasons people mute videos: removing background chatter from a screen recording before sharing, stripping copyrighted music from a phone clip you want to post on a platform that flags it, anonymizing audio in a clip going to a meeting where the original speaker shouldn't be heard, or just creating a silent loop for a website hero background.

Everything runs locally via HTMLVideoElement.captureStream() + MediaRecorder. No upload, no server, no watermark. The audio track is simply not included in the recording — there's no half-mute or "lower volume" option because what you're getting is a brand new video track with no audio at all.

How to use it

1. Drop a video file into the upload area, or click to browse.
2. Hit play on the preview — the player is muted by default so you can confirm what you're working with.
3. Click Mute & Export. The tool plays the video at 1× speed in the background while recording the visual stream into a new file.
4. Wait for processing to finish (real-time = a 2-minute video takes 2 minutes to process). A progress bar shows where you are.
5. Click Download to save the new audio-free WebM file.

How it works

The browser plays your uploaded video into a hidden <video> element. We call video.captureStream() to get a MediaStream with both video and audio tracks, then immediately remove the audio tracks before passing it to a MediaRecorder:

const stream = videoEl.captureStream();
stream.getAudioTracks().forEach(t => stream.removeTrack(t));
const recorder = new MediaRecorder(stream, { mimeType: 'video/webm' });

The recorder produces a WebM file with VP8 video and no audio. Recording happens in real time (1 second of video = 1 second of processing) because MediaRecorder ticks off the system clock. That's why long videos take a while — there's no faster path through the browser API.

When to use this tool

• Removing copyrighted music from a phone clip before posting to TikTok/Instagram/YouTube Shorts.
• Stripping ambient noise / chatter from a screen recording.
• Anonymizing audio in a clip you need to share but the speaker shouldn't be identifiable.
• Creating silent loops for website hero videos (most browsers require muted videos to autoplay anyway).

When not to use it

• When you want to keep but reduce audio volume — this strips it entirely. Use a video editor for partial mute.
• When you want to keep the original codec/container — output is always WebM/VP8 because that's what MediaRecorder writes.
• Long videos (>30 minutes) — processing time = video length, and browser memory will be a bottleneck.
• When file-size minimization matters — re-recording produces a different bitrate than the original; for source-preserving mute, use ffmpeg locally with `-c copy -an`.
