Remove Audio From Video

Strip the soundtrack out of a video without touching a single frame. The picture is copied, not re-encoded, so it finishes in seconds and looks exactly as it did.

The converter is ffmpeg compiled to WebAssembly. It downloads once (30 MB) when you pick your first file, then stays in your browser cache.

Your file is processed by your own browser and never uploaded. The engine itself is a one-time 30 MB download the first time you use it, and after that it comes out of your browser cache.

How to use Remove Audio From Video

  1. 1Drop your video onto the box above, or click to pick a file.
  2. 2The audio track is dropped and the video streams are copied across unchanged. There is nothing to configure.
  3. 3Download the muted file. Its name gets a -muted suffix so you do not overwrite the original.

Copying, not converting

Almost every other tool on this site decodes something and encodes it again. This one does not, and the difference is worth understanding because it is why the result is trustworthy.

A video file is a container holding separate streams. To remove audio from video, you only have to write a new container with the video packets copied in and the audio packets left out. No frame is ever decoded, no encoder makes a single decision, and the picture that comes out is bit-identical to the one that went in. This is called remuxing, and it takes seconds even on a large file.

Any tool that re-encodes to do this is doing avoidable damage. You will wait minutes, and you will get a slightly softer picture with new compression artifacts, in exchange for nothing.

Why people need it

The reasons cluster into a few shapes. Music playing in the background of a clip triggers a copyright claim on upload, and the video itself is fine. On-camera audio came out unusable and a proper voiceover is going over the top. The clip is b-roll that will sit under someone else's narration. A screen recording captured system sound nobody wants. Or the clip is destined for a social feed that autoplays muted anyway, and shipping a silent file removes any doubt about what viewers hear.

In all of those, the video is the asset and the audio is the problem. Keeping the picture untouched is the entire requirement, whether you would describe the job as wanting to mute a video or to remove sound from video you are about to re-score.

What comes out

The same container, with the same video stream, minus the audio. Subtitle and data tracks are dropped too, because they can prevent a clean remux and neither is what someone asking to mute a video came for. MP4-family files also get their index moved to the front, so the result starts playing without downloading the whole file first.

The filename gains a -muted suffix, so nothing overwrites your original. Files up to 500 MB are accepted, and everything runs in your browser using ffmpeg compiled to WebAssembly.

Now give it a new voice

Stripping the audio leaves a silent clip, which is usually the halfway point rather than the goal. Generate a voiceover from a script and lay it back over the footage.

Frequently asked questions

Does this reduce the video quality?
No, not at all, and that is the main thing worth knowing about this page. The video stream is copied byte for byte into a new container rather than being decoded and re-encoded. The result is pixel-identical to the source. Tools that re-encode take minutes and visibly soften the picture for no reason.
Why is it so much faster than other conversions?
Because nothing is compressed. The work is reading the file, discarding the audio packets, and writing the video packets back out. That runs at disk speed rather than encoder speed, so a large file that would take five minutes to transcode finishes here in a few seconds.
Can I get the audio back afterwards?
Not from this file. The audio is gone from the output, so keep the original if you may want it later. If what you actually wanted was the audio, our MP4 to MP3 tool extracts it instead of discarding it.
Does the file get smaller?
A little, by exactly the size the audio track occupied. On a typical video that is a few percent, since the picture accounts for almost all of the bytes. This is not a way to make a video smaller.
Which formats work?
MP4, MOV, M4V, MKV, WebM, AVI and most other common containers. The output keeps the same container as the input, which is what guarantees the copied video stream is still valid inside it.
