Remove sound from a video
Background noise, a stray conversation, music you do not have the rights to. Take it off, keep the picture exactly as it was.
Everything happens inside your browser, using your own computer’s memory. Your file is never uploaded, never stored, and nothing is sent to us — so there is no limit on how often you use this.
How removing the sound works
At a glance
- Opens
- MP4, MOV, MKV, WebM — any video your browser can read
- Saves
- The same type as your file, without the sound
- Picture
- Copied bit for bit — no quality change at all
- Speed
- Seconds, even on a large file
- Memory
- Far lighter than any re-encode — the file only has to fit
- Keeps
- Every video stream; only the sound is left out
How it works
A video file carries its picture and its sound as separate tracks. Removing the sound does not require touching the picture: the video track is copied into a new file exactly as it is, and the sound track is simply not included.
Because nothing is decoded or encoded, it takes seconds even on a large file, needs far less memory than any re-encode, and the picture is identical to the original down to the last bit.
Step by step
- Drop the videoIt opens in this tab. Nothing uploads. The first time, the browser downloads the 32 MB video engine and keeps it.
- Remove soundThere is nothing to choose — the picture is copied and the sound is left out.
- DownloadIt keeps its original type. The file stays in this browser until you press Delete.
Which setting for which job
| If you are… | Choose |
|---|---|
| You will add a trending sound inside Instagram or TikTok | Remove sound, then add the sound in the app |
| Background noise, a conversation or a phone ringing | Remove sound |
| Music in the clip you do not have the rights to | Remove sound — it is the usual reason posts get muted |
| You only want the voice without the music | Not this tool — separating them is editing work |
Under the hood
The technical detail, for anyone who wants to know exactly what happens to their file. Each line first says it plainly.
Stream copy
No decoding, no encoding.
With -c copy the compressed video is moved into the new file unchanged. That is why it is fast and lossless. The file itself still has to fit in the memory the browser gives the page, but no frames are decoded, so it needs far less than any tool that re-encodes.
-an and -map 0:v
Picture in, sound out.
-map 0:v selects every video stream in your file; -an tells ffmpeg to write no audio at all.
Container kept
Same type as you gave it.
The result is written in the same container — MP4, MOV, MKV or WebM — because a copy never needs a different one. MP4 and MOV get their index moved to the front for instant playback.
Copyright matching
Why muted posts happen.
Platforms fingerprint the sound in every upload and compare it with licensed music. A track playing in the background of your clip can be matched even when it was not the point of the video.
If something goes wrong
| What you see | Why | What to do |
|---|---|---|
| I wanted to keep my voice | This tool removes the whole sound track; the voice and the music are mixed together in it. | Keep the original and have Ruzz separate them in an edit — or re-record the voice over the muted clip. |
| The result is the same size as before | Sound is a small part of a video file; the picture is almost all of it. | Use Compress if you need the file smaller. |
| My player says the file has no audio | That is the result working as intended. | Add the sound you want inside the app when you post. |
Privacy: your file stays on your computer
Removing the sound happens in your browser. The original, with its sound, never leaves your device.
- What your browser downloads
- The page — and, the first time you use a video tool, the video engine: about 32 MB, then kept in your browser's cache.
- What it sends to us
- Nothing. There is no upload step, no copy on our servers and no account. The work happens in your computer's memory.
- How we know
- Our automated tests run every tool while recording every network request the page makes. A single upload fails the test.
- Where the result lives
- In this browser only, until you press Delete. A finished file is still here if you close the tab and come back; a job still running stops when the tab closes.
Questions
Does this lower the video quality?
No. The picture is copied, not re-encoded, so it is identical to the original.
Can I remove only the music and keep the voice?
Not with this tool — it removes the whole sound track. Separating voice from music is editing work.
Why would I post a silent video?
So you can add a trending sound inside the app. Sounds added there sit cleanly on a silent clip instead of on top of street noise.
Is my video uploaded?
No. It happens in your browser, and the file never leaves your device.
A tool makes a file fit. It does not make people watch to the end — that is the hook, the order of the shots, the captions and the music. See how Ruzz does it.
Other free tools
Compress video
Too big to upload, email or text? Make it small enough, without it looking bad. Takes a few minutes.
