Mute video (remove audio)

Strip the audio track from your video. Instant copy mode keeps the picture untouched, or re-encode for players that need it.

How Mute video works

Strip the audio track from any video file with ffmpeg WebAssembly. It removes the sound stream and rewrites the container in copy mode, so the video image quality is completely unchanged and the process is almost instant regardless of clip length.

The silent output is perfect for social posts, background loops, presentation assets, or any video you want to share without a soundtrack. Because only the audio is dropped and no pixels are re-encoded, the picture stays bit-for-bit identical to the original.

Frequently asked questions

Are my files uploaded to a server?

No. ffmpeg compiled to WebAssembly removes the audio in this browser tab, your video is read into memory on your own device, ffmpeg drops the sound stream with -an while stream-copying the video (-c:v copy), so the picture stays bit-for-bit identical, and the silent file is offered as a local download. Nothing reaches Sunasty or any third party. Open your browser's DevTools, go to the Network tab and watch: no request carries your video.

Does muting the video affect image quality?

No. The tool drops the audio stream and copies the video stream unchanged, no pixels are re-encoded. The output file is identical in resolution, frame rate, and visual quality to the original; it is simply smaller because the audio data is gone.

Can I mute just part of a video, keeping audio on the rest?

This tool mutes the entire clip. If you need selective audio removal, silencing only a segment, use the video-trim tool to extract the portions you want and then mute them individually before re-joining with the video-merge tool.

Does it work offline?

Yes, once the page and the ffmpeg engine have loaded. The engine is fetched on first use since it is sizeable, but after that muting a video requires no internet connection at all.

Is it free? Do I need an account?

It is completely free and requires no sign-up. There are no watermarks, no daily limits and no tracking cookies needed to use the tool.
