Video Sound Remover.

A video sound remover that can also silence just one part.

How it works.

Take the sound out and keep the picture.

  1. Step 1

    Drag your video in

    Or click to choose a file. It stays on your device.

  2. Step 2

    Pick what goes

    All of it, or only the part you mark.

  3. Step 3

    Save the silent version

    One click, and it downloads.

In detail

Most sound removers have one button, and one button is often the wrong tool: a phone rang for six seconds in the middle of a nine minute take, and losing all nine minutes of sound to fix six seconds of it is not a repair. So this has three answers. Take the whole track out, which is free and instant because the picture is only ever copied. Replace it with digital silence, for the platforms and editors that refuse a video with no audio track at all. Or put an in and an out around the part that has to go and silence exactly that, with the waveform drawn under your marks so you can see the noise you are aiming at. All three run on your own machine with nothing uploaded.

What it gives you.

  • The track gone in about a second

    Removing audio needs no encoder at all: the video packets are copied into a new container exactly as they were and the audio ones are left out. Nothing is re-compressed, so the picture that comes out is bit for bit the picture that went in, and the job takes about as long as your disk takes to read the file.

  • A silent track when something wants one

    Instagram, some television playout systems, and a good number of editing timelines treat a video with no audio track as a broken file. So there is a second mode that keeps a track and fills it with digital silence, encoded as AAC in an MP4 or Opus in a WebM at 48 kHz, matching your source's channel count.

  • Silence just the part that has to go

    Mark an in and an out on the waveform and only that span is zeroed. The audio either side of it is re-encoded once at its own bitrate and everything you wanted to keep is still there, which is the difference between fixing a recording and throwing its sound away.

  • A waveform you can aim at

    The span mode draws the real peaks of your audio across the clip, so the conversation, the cough, or the song you are trying to lose is a shape you can see and put the marks around instead of a timecode you have to guess.

  • Any format in, the same format out

    An MP4 comes out an MP4, a WebM comes out a WebM, and a MOV comes out an MP4 because that is the file anything downstream would rather have. Your codecs are not swapped behind your back to make the tool's life easier.

  • Nothing uploaded, no watermark

    The whole thing runs in a worker on this page: the file is opened from your disk, rewritten in memory, and handed back. There is no upload, no account, no queue, and nothing stamped in the corner at any size.

Straight answers.

Is there a sound remover that can mute part of a video instead of all of it?

This one. Switch to the span mode, and the waveform of your clip is drawn across the width of the strip with two marks on it. Put them either side of the noise and only the samples between them are zeroed. The video is still copied untouched, the audio outside your marks arrives intact, and the plan line names the two timecodes before you commit so you can check them against what you heard. It is the difference between removing a problem and removing your whole soundtrack.

Does removing the audio change the video quality?

No, and this is the one operation where that is unambiguously true. A video file is a container holding separate streams of already-compressed video and audio packets. Removing the sound means writing a new container with only the video packets in it, copied across without being decoded or re-encoded, so the picture in the output is identical to the picture in the input down to the byte. The file gets smaller by exactly the size of the audio, which for a typical 128 kbps stereo track is about a megabyte a minute. Nothing else changes.

Why would I want a silent audio track instead of no audio at all?

Because a surprising amount of software refuses a video without one. Instagram has rejected audio-less uploads for years, some broadcast and playout systems will not ingest a file with a missing track, and a number of editing timelines either throw an error or silently drop the clip. Replacing the sound with a generated silent track keeps every one of those happy: the file still says it has audio, that audio is genuinely, measurably nothing, and the cost is a few kilobytes because silence compresses to almost zero.

Can I mute only part of the video?

Yes, and that is the third mode. Mark an in and an out on the waveform and the samples inside that span are set to zero while everything outside it is kept. The picture is still copied untouched, so the only stream that pays anything is the audio, which is decoded, zeroed inside the span, and encoded again in the codec it arrived as when your browser can write it. One audio re-encode at the source's own bitrate is inaudible in practice, and it is the honest price of keeping the rest of the sound.

Will YouTube still flag my video if I remove the audio?

If the music was in the audio track, and the audio track is gone, then there is nothing left for Content ID to match against, and a claim raised against the sound of a video with no sound does not survive. What removing the audio cannot fix is a claim on the picture, which happens if you have used somebody else's footage, and it cannot undo a claim that has already been resolved against you. If only part of your video has music in it, silencing that span is usually the better answer than muting the whole thing: it clears the match and you keep the rest of your sound.

Which formats can it open?

MP4, MOV, MKV, and WebM, which covers phone recordings, screen captures, camera files, and downloads. The container the file arrives in is the container it leaves in, with MOV the one exception because an MP4 is what everything downstream would rather be handed. AVI and the older oddities have to go through the converter first: the browser has no parser for them, so there are no packets to copy in the first place.
