Remove the audio from a video
Drop a video and download the same video with no sound. The picture is copied untouched, so it takes seconds and loses nothing. Runs in your browser; nothing is uploaded.
Runs in your browser with ffmpeg. The file is never uploaded.
About the mute video
Muting a video is the simplest edit there is, and most online tools still manage to make it slow: they upload the file, re-encode the whole thing at a lower quality and give it back with a watermark. Removing an audio track does not require touching the video at all. A container like MP4 holds separate streams, and dropping one of them is a copy operation: this tool reads the file, writes a new one with the video stream copied byte for byte and the audio stream left out, and fixes up the index. The result is bit-identical picture quality, a slightly smaller file, and a wait of seconds even for a long recording, because nothing is decoded or encoded. That makes it the right tool for the common reasons to mute: a screen recording with keyboard noise or a conversation in the background, a clip going to a platform where you will add music, a video with copyrighted audio that would get it flagged, or background noise on a product demo. The file keeps its container, so an MP4 stays MP4 and a MOV stays MOV. The whole job runs on your device with ffmpeg compiled to WebAssembly.
How it works
Drop your video
MP4, MOV, WebM or MKV, up to 500MB. It is processed in your browser with ffmpeg, nothing is uploaded anywhere.
Pick the settings
Times, quality, size or speed depending on the tool. A progress bar shows how far along the export is.
Download
The result saves to your device. Free, no watermark, no signup.
Tips for best results
Things that meaningfully improve the output.
Mute before adding music elsewhere
Most social apps mix your original audio with the added track. Muting first gives you a clean base.
It is lossless, so it is safe to do early
Since the picture is copied, muting costs nothing in quality. You can do it before compressing, trimming or resizing.
Background noise vs. speech
If you want to remove noise but keep the voice, that is a different job (audio cleanup). This tool removes all sound.
Check platforms that require audio
A few places, like some ad platforms, reject videos with no audio track at all. For those, keep the audio and lower the volume in an editor instead.

Does muting change the video quality?
No. The video stream is copied without decoding, so the picture is bit-for-bit identical to the original.
How long does it take?
Seconds, regardless of length, because no re-encoding happens. Only the file has to be read and rewritten.
Is my video uploaded?
No. The operation runs in your browser with ffmpeg compiled to WebAssembly.
Can I remove only the background noise?
No, this removes the whole audio track. Noise reduction while keeping speech needs an audio tool.
Will the file be smaller?
Yes, by the size of the audio track: typically 5-15% for a phone recording, more for a screen capture with high-bitrate audio.
