How do I remove audio from a video for free?

Choose a video and press Remove audio. There are no settings to configure — the audio track is dropped and the video stream is copied across untouched, so it finishes in seconds rather than minutes. Nothing is uploaded at any point.

Does muting reduce the video quality?

Not at all, and this is the one job where that is genuinely true. The video stream is copied rather than re-encoded, so the frames in your output are the exact same encoded frames as in the input. There is no generation loss because there is no generation — nothing was decoded and rebuilt.

Why is this so much faster than other video tools?

Because no frames are decoded or encoded. Almost every other operation — resizing, cropping, rotating — has to rebuild every frame, which is CPU-bound and roughly real time. Muting only rewrites the container to leave the audio track out, so it runs at disk speed.

How much smaller will the file be?

Usually only a few percent. Audio typically runs at 128 to 256 kbps against video at several megabits, so it is a small share of the total. A quiet talking-head clip recorded at a low video bitrate sees the biggest reduction; a high-bitrate 4K clip will barely change size at all.

Which formats can I mute?

MP4, MOV, WebM and MKV, up to 500MB. AVI is not accepted here — convert it with the video converter first if you need to. The output keeps your original container, so an MKV stays an MKV rather than being forced to MP4.

Can I lower the volume instead of removing the audio completely?

No — this is all or nothing, because a partial volume change would require re-encoding the audio and would lose the speed and lossless advantage. For volume levelling use the normalize video tool, which is built for adjusting audio rather than removing it.

Can I replace the audio with different music?

Not with this tool. Mute first, then use the add audio to video tool to lay a new track over the silent result. Doing it in that order is the reliable route, since it avoids two audio streams ending up in the same file.

Is my video uploaded anywhere?

No. FFmpeg compiled to WebAssembly runs inside the browser tab, so private recordings, client work and family video stay on your device. The first run downloads roughly 31MB of engine code, which the browser caches for later visits.

or import from

Remove audio from a video without touching a single frame. The audio track is dropped and the video stream is copied, not re-encoded — so it finishes in seconds with zero quality loss. Runs entirely in your browser: no upload, no sign-up, no watermark, up to 500MB.

Why this one is instant

Most video tools have to decode every frame, apply a change and encode it all again, which is why they run at roughly real time. Muting does not touch the picture at all. The container is rewritten to leave the audio track out and the video stream is passed through byte for byte.

Two consequences worth having straight. It runs at roughly disk speed rather than playback speed, so a long recording mutes in seconds. And the result is genuinely lossless — the encoded frames in your output are the same frames that were in the input, not a re-compressed copy of them. On this page the usual "visually indistinguishable" hedge is not needed.

How much smaller is the file?

Less than people expect. Audio usually runs at 128–256 kbps while video runs at several megabits, so removing it typically saves only a few percent. The exception is a quiet, low-bitrate clip — a screen recording of a slide deck with a voice-over can be meaningfully smaller once the voice-over is gone. A high-bitrate 4K clip will barely change at all.

If size is the actual goal, muting is the wrong lever. Thevideo compressor targets file size directly, andresize video cuts resolution, which is the biggest factor of all.

Why people mute videos

Copyrighted background music. A clip with a radio playing in the background gets muted or blocked by platform matching. Removing the audio is the fastest fix.
Overheard conversation. Screen recordings and phone footage pick up voices in the room that have no business being published.
Wind and handling noise. Outdoor footage often has audio that actively detracts from it.
Silent-by-design content. Background loops, website hero video and digital signage should carry no audio track at all, not just a muted one.
Replacing the soundtrack. Strip first, then add the new track cleanly.

That last case matters more than it sounds: publishing a file with a silent-but-present audio track is not the same as publishing one with no audio track. Some players still show controls, and some pipelines still transcode the empty stream.

How this compares to the alternatives

Removing an audio track.
	ToolJiffy	Typical online tool	Desktop editor
Video uploaded to a server	No	Yes	No
Re-encodes the video	No — stream copy	Often yes	Depends on export settings
Quality loss	None	One generation if re-encoded	None if you copy the stream
Speed	Seconds	Upload + queue + download	Seconds

Watermark	Never	Common on free tiers	No
Price	Free, unlimited	Free tier then paid	Free to paid

The re-encode row is the one to check on any other tool you try. A muter that rebuilds the video costs you quality for no reason whatsoever — there is nothing about removing audio that requires touching the picture.

Scope and limits

One file at a time, no options, and all or nothing — there is no volume slider, because changing volume means re-encoding the audio and would forfeit both the speed and the lossless guarantee. Accepted formats are MP4, MOV, WebM and MKV; AVI is not on the list, so convert it first if you need to. The output keeps your original container, so an MKV comes back as an MKV. Files are capped at 500MB, and the engine is about 31MB to download on first use.
