Mute a video
Strip the soundtrack when you need silent B-roll, a social clip with music added later, or a recording that picked up room noise. The picture is re-encoded so the file stays an MP4 even when the source was not.
Run this tool
Files stay under 20 MB. Successful encodes use compute seconds. Failures are not billed.
How it works
- 01Upload the video you want silenced.
- 02FFmpeg drops every audio stream and writes an H.264 MP4.
- 03Download the silent file. A successful mute uses compute seconds from your plan.
Limits
- Each file can be up to 20 MB. Successful runs count against your monthly compute seconds and request quota. Failed encodes are not billed.
- The picture is re-encoded. Stream copy would fail on formats that cannot sit in an MP4.
- There is no volume slider. This tool removes the audio track entirely.
FAQ
Can I turn the volume down instead of removing it?
Not on this page. The audio track is removed. Use the API if you need a volume filter.
Why does muting take as long as a convert?
The video is re-encoded so WebM, MKV, and odd MOV files still come back as MP4. Copying the video stream is faster only when the source is already compatible.
Is the original audio recoverable from the result?
No. Download a copy of the source first if you still need the soundtrack.

Need this in your app?
The same encode is available as POST /v2/run. Send the inputs and FFmpeg args from your own code, and pay only for successful compute seconds.
