How do I remove the sound from a video?
Choose your video and press Make a silent copy. The tool plays the video and records only the picture, in your browser, so the new file has no audio track. It takes about as long as the video is long. The original is not changed, and nothing is uploaded.
Why we built this tool
There are many good reasons to take the sound off a video: a recording that picked up a private conversation, a clip with music you do not have the right to use, a screen recording where background noise ruins an otherwise good demo, a video you will put on a website as a silent background, or a clip you will add new narration or music to. Doing it in an editor means installing one and learning it; doing it online usually means uploading the video. This tool strips the sound in your browser and gives you a clean, silent copy.
Your video is processed in your browser. Nothing is uploaded, and there is no watermark.
How it works in detail
The video is opened in a hidden player with its sound off. Each frame is drawn on a canvas, and only the canvas is recorded with MediaRecorder, so the new file is made without any audio track at all, not just with the volume turned down. That matters for privacy: a silent copy cannot be turned back into a copy with sound. The picture is encoded again, so there is a small quality cost; choose a higher quality setting if the picture matters. Because the video is recorded as it plays, the work takes about as long as the video itself.
How to use it
- Choose your video.
- Leave 'Remove the sound' ticked, and choose the quality and format.
- Press Make a silent copy and keep the tab open until it finishes.
- Play the copy to check it is silent and the picture is right, then download it.
Use cases
- Removing private conversation or background noise from a recording
- Avoiding copyright problems from music in a clip
- Making a silent video for a website background or a presentation slide
- Preparing a clip to add your own voice-over or music
- Sharing a screen recording without the sound of your room
- Creating a looped video for a display
Problems you may run into
Most trouble is about formats and time.
| What you see | Likely cause | What to do |
|---|---|---|
| It says it cannot read my video | The browser cannot play that codec (for example HEVC/H.265 in some browsers, or a camera's special format) | Try Chrome, Edge or Safari, or convert the file to H.264 MP4 first |
| It takes as long as the video | The video is recorded as it plays; there is no shortcut in a browser | Use a shorter clip, or start it and leave the tab in front while you do something else |
| The output stops or the picture freezes | The tab was hidden, the computer went to sleep, or it ran out of power | Keep the tab open and visible, plug in a laptop, and run it again |
| The quality is a little lower than the original | The video is decoded and encoded again, which always costs some quality | Choose High or Very high quality, and keep your original file |
| The file is WebM and my app wants MP4 | Most browsers can only record WebM | Choose MP4 where your browser offers it (recent Chrome, Edge, Safari), or convert the file afterwards |
| I wanted to remove only part of the sound | This tool removes all of it | To mute a section, trim the video into parts first, or use a video editor |
Privacy and rights
The video stays on your device. Removing the sound removes the audio from the new copy only; the original file still has it, so delete or secure the original if the sound was the private part.
How it works
The video is played, redrawn and recorded again in your browser.
1. The video is opened in a hidden player in your browser; nothing is uploaded.2. The player runs from the start point while each frame is drawn on a canvas (turned, resized or mirrored if you asked).3. The browser's MediaRecorder records the canvas and the sound as a new video.4. When the end point is reached the file is finished and offered as a download.
This uses the browser's own encoder, so the output is WebM (VP8/VP9) or, in browsers that can record it, MP4 (H.264). It is a new encoding, not a lossless cut, so there is a small quality cost, and the work takes about as long as the part you choose. The tab must stay open and visible. Very long videos (over about an hour) may exhaust memory; cut them into parts first. Files protected by copy protection (DRM) cannot be processed.
Example: a screen recording with background noise
A 3-minute screen recording has a loud fan.

Common questions
Is it free, and is my video uploaded?
It is free, and your video is processed in your browser and never uploaded.
Is the sound really gone?
Yes. The copy has no audio track, so it cannot be restored.
Does it change the original file?
No. It makes a new file.
Why does it take as long as the video?
The picture is recorded as it plays.
Can I add new music afterwards?
Yes, with a video editor. This tool only removes the sound.
Is anything I enter sent to a server?
No. The calculation happens in your browser and nothing you type leaves your device.
