How to use Mute Video

- 2Run it — the audio track is simply omitted
- 3The video stream is copied, not re-encoded
- 4It finishes in seconds regardless of file length
- 5Download the silent video
What Mute Video does
Muting a video is the simplest operation on this site. A video file holds separate streams, and removing the sound means writing a new file that contains the video stream and nothing else. The picture is copied byte for byte, so there is no encoding, no quality loss and no waiting.
It is worth being clear about what this is not. The audio is removed, not silenced — there is no track at all, rather than a track full of zeros. Anything a player, an editor or a transcription service would have read from that track is gone from the output entirely.
When to use it
- Background video on a web page
- Browsers block autoplay for videos with audio. Removing the track entirely is more reliable than setting a muted attribute, which a user or an extension can undo.
- Recordings with unwanted background noise
- A clip where the picture matters and the audio is a conversation, a television or wind noise. Removing the track is quicker than editing the sound.
- Removing incidental speech
- A screen recording or a phone clip that captured people talking nearby. Muting removes what was said without touching the footage.
- Preparing footage for a new soundtrack
- An editor importing silent footage cannot accidentally use the original audio, and the import is smaller and faster without it.
Mute Video settings explained
- No options
- There is nothing to configure. The audio track is dropped and the video stream is copied, which is the only sensible behaviour — any setting would imply re-encoding the picture for no reason.
- Stream copy
- The video is copied rather than re-encoded, so the output is pixel-identical to the source and the operation finishes in seconds even on a large file.
- Output container
- The source container is kept where it can hold the copied video stream — MP4, WebM, MOV, MKV or AVI. Anything else is written to MKV, which accepts nearly any codec.
- The track is removed, not silenced
- There is no empty audio stream in the output. Some software behaves differently with a file that has no audio track versus one with a silent track, and this produces the former.
Removing audio compared with the alternatives
| Approach | Audio in the file | Reversible by the viewer | Quality cost |
|---|---|---|---|
| Mute (this tool) | Removed entirely | No | None |
| Player volume at zero | Still present | Yes | None |
| HTML muted attribute | Still present | Yes | None |
Limits and what to expect
- The audio is discarded, not saved — extract it first if you want to keep it.
- Only whole tracks; a section of audio cannot be removed while keeping the rest.
- The output stays in a container that accepts the copied video codec, which may not be MP4.
- Files whose container cannot hold the copied stream are written to MKV.
- The file size drops only by the size of the audio track, typically a small share of a video.
Troubleshooting
- The file barely got smaller
- Audio is usually a small fraction of a video's size — often under a tenth. Muting is about removing the sound, not reducing the file. Use the compressor if size is the goal.
- I wanted to keep the audio separately
- This discards it. Run the extract-audio tool on the original first to save the sound as MP3 or WAV, then mute the video.
- The output is an MKV, not an MP4
- The video codec could not be copied into the source container, so MKV was used because it accepts almost anything. Convert it afterwards if MP4 is required — that pass does re-encode the picture.
- I only wanted to silence part of the video
- This removes the whole track. Selective silencing needs an editor that can work on the audio timeline; extract the audio, edit it, and recombine in a video editor.
Your files and your privacy
The file is processed by an ffmpeg build running in your browser through WebAssembly, on your own device. Nothing is uploaded. That is worth noting for this tool specifically, since removing an audio track is often exactly because it captured a conversation that should not be shared — sending the file to a server to strip it would defeat the purpose.

FAQ
Does removing audio reduce video quality?
No. The video stream is copied rather than re-encoded, so the picture in the output is bit-identical to the source. Only the audio track is absent.
How much smaller will the file be?
Only by the size of the audio track, which is usually a small share of a video — often under a tenth. If your goal is a smaller file rather than silence, the compressor is the right tool.
Is the audio silenced or removed?
Removed. The output has no audio stream at all rather than a stream of silence. That distinction matters to some software, which behaves differently with a file that has no audio track than with one carrying a silent one.
Can I get the audio back afterwards?
Not from the muted file — it is gone. Your original is never modified, though, so extract the audio from that if you need it.
Why is this so much faster than compressing?
Because no encoding happens. The video stream is copied as-is and the audio is simply left out, so the work is essentially rewriting the container. Compression decodes and re-encodes every frame.
Is my video uploaded?
No. Everything runs in your browser through WebAssembly, with nothing transmitted to any server.
