The video stays on your device. FFmpeg runs in the browser only after you start processing, and the large WebAssembly engine is served from this site.

Quick answer

A video mute tool removes the audio track from a video and exports a silent copy.

This browser-side version is best for short clips under 200MB.

Best inputs

Short local videos

Smaller clips finish faster and use less memory on mobile devices.

Clear destination format

Choose MP4 for broad compatibility or WebM for browser-native publishing.

Mute method
The tool writes the video into browser memory and re-encodes a silent output with ffmpeg.wasm.
The audio track is removed with the output set to silent.
CRF controls visual quality and output size.
Resolution limits can reduce file size when full resolution is unnecessary.
Example, Assumption, and Limitation
Use the result as a practical estimate or transformation, then confirm edge cases for critical work.

Example

Upload a short MP4 product clip, keep MP4 output, remove audio, and download a silent preview for a landing page.

Assumption

The source video is under 200MB and the browser has enough memory to process it.

Limitation

This tool does not edit captions, subtitles, or multiple audio-track choices. It creates a silent video output.

Common use cases
These pages are built for lightweight browser-side work, examples, and planning.

Silent autoplay

Prepare silent clips for web pages or social previews.

Privacy cleanup

Remove background audio before sharing a screen recording.

Product demos

Create quiet looping videos for documentation or landing pages.

Smaller exports

Remove audio when sound is not needed.

Frequently asked questions

Does this video mute tool upload my file?

No. The selected video is processed in your browser with ffmpeg.wasm and is not sent to a backend.

What output formats are supported?

The first version exports silent MP4 or WebM files with browser-side re-encoding.

Will the video quality change?

The tool re-encodes the video while removing audio. Use a lower CRF for higher quality or a higher CRF for smaller files.

What file size should I use?

Use videos under 200MB for this browser-side version. Smaller clips are recommended on mobile devices.
