Does muting re-encode the video?

No. Muting uses copy-stream mode, which removes the audio track while copying the video track unchanged. This preserves full video quality and finishes in seconds regardless of video length.

Why would I want to mute a video?

Common reasons include: removing background noise or copyrighted music before uploading to social media, creating a silent video loop for a website background, and stripping confidential audio from a screen recording before sharing.

What if I want to keep the audio separately?

Use the Audio Extractor tool at /video/audio-extract/ to save the audio as an MP3 or WAV file before muting the video.

Which input formats are supported?

ffmpeg.wasm supports MP4, WebM, MOV, MKV, AVI, and most other common video containers. MP4 and WebM work most reliably.

Is my video uploaded during muting?

No. ffmpeg.wasm processes your video entirely in your browser. Nothing is sent to any server.

How fast is the muting operation?

Because the video track is copied without re-encoding, muting is near-instant — typically 1–5 seconds for any file size.

What format is the output?

The output is MP4. The video track is preserved exactly from the input; only the audio track is removed.

Can I add a different audio track after muting?

This tool only removes audio. To replace audio, mute the video here, then use a video editing application that supports audio track replacement.
