Mute Video
Upload a video to remove its audio track — processed instantly in your browser.
All processing happens in your browser — your files are never uploaded.
How to use Mute Video
The Mute Video tool strips the audio track from an MP4, WebM, MOV or MKV file and outputs a silent video — processed entirely in your browser so no footage is ever uploaded. Use it to remove background noise, music or confidential conversation from a screen recording, tutorial or presentation before publishing or sharing.
- Click "Select Video" and open the video file you want to mute.
- Preview the video to confirm it is the correct file and note the duration.
- Select "Stream copy" for instant muting or "Re-encode" to also change codec or resolution.
- Click Mute Video and wait for the browser to process the file.
- Download the silent video file when the export is ready.
Your data never leaves your device — 100% private processing.
When to mute vs replace audio
Muting is the quickest way to remove unwanted sound — a microphone hum, copyrighted background music or sensitive speech — before uploading to a platform. If you need to add a new soundtrack instead, use the audio replacement workflow: mute first, then merge the silent video with your chosen audio track. Muting with stream copy takes only a fraction of a second because the video data is untouched; only the audio stream is dropped from the container.
Privacy and confidentiality use cases
Screen recordings of business software often contain audio notifications, colleague conversations or system sounds that should not be shared externally. Muting the video before distribution ensures no accidental audio disclosure. Because this tool runs fully in the browser, the video frames and audio are never transmitted to a remote server, satisfying most internal data-handling policies without needing special approval.
