How to Mute a Video (Remove the Audio Track in One Click)

Strip the audio track from a video instantly — lossless, no re-encode, all in your browser.

Muting runs locally via Zro7 Mute Video using ffmpeg.wasm. Videos never leave your browser.

To mute a video, use Zro7 Mute Video. It drops the audio track from the container without touching the video stream — the file gets a bit smaller, the picture is byte-identical, and it takes seconds even for GB-sized recordings. Nothing is uploaded.

Mute vs silence

  • Mute (strip track) — removes the audio stream entirely. Smaller file, no volume setting, no track at all. This is what Zro7 does by default.
  • Silence (keep track) — replaces samples with zeroes. Same file size, but the track still exists. Rare; useful when a downstream tool requires an audio track present.

Why mute?

  • Screen recording with a phone ringing in the background.
  • Client footage where you must strip identifying voices before sharing.
  • Social clip meant to autoplay silently.
  • Prep for a voiceover replacement in an editor.

Steps

  1. Open Mute Video.
  2. Drop the video.
  3. Click Mute.
  4. Download the silent copy.

Frequently asked questions

Does this re-encode the video?

No. The video stream is copied; only the audio stream is dropped.

How much smaller is the output?

Audio is usually 5–15% of a video's bytes. Expect a modest size drop.

Can I mute only part of the video?

That requires re-encoding audio with silenced ranges. Use <a href="/audio-volume">Audio Volume</a> after extracting audio, then remux.

Which formats work?

MP4, MOV, MKV, WebM, AVI — anything FFmpeg can demux.

Any upload?

No. ffmpeg.wasm runs in your browser.
