1Upload the WebM videos whose soundtrack you want gone.
2Confirm that you want the audio track dropped entirely rather than turned down to silence.
3Run it; the audio track is removed and the picture is copied through untouched.
4Download the silent WebM file, which is also smaller than what you started with.
Mute WebM FAQ
Should I mute or just silence the audio?
+
Mute. A silent track still occupies bitrate and still has to be decoded by the player; dropping it makes the file smaller and removes any chance of it being unmuted downstream.
Is the video re-encoded when I mute it?
+
No. Removing a track is a container operation, so the video stream is copied bit-identically and is not re-encoded, however long the clip is.
Does the container format matter?
+
It does. WebM is the royalty-free web container — VP9 or AV1 video with Opus audio, decoded natively by every modern browser. That governs how the tracks are stored and therefore how cleanly one can be dropped.
Anything specific to WebM worth knowing?
+
Yes — WebM is VP9 or AV1 with Opus audio, which browsers decode natively but which most desktop editors still transcode on import. Relevant when the source has more than one audio track.
Can I run Mute WebM on several WebM videos at once?
+
Yes. Uploads queue in parallel, which matters more here than anywhere else because video jobs are minutes rather than seconds. Free accounts run one file at a time; a pass lifts that.
Does Mute WebM cost anything?
+
No. Mute WebM is free without an account, and the output has no watermark, corner logo or intro card. The upload and the result are deleted automatically about 24 hours after the job, which leaves time to download the result.
Why does a WebM site host Mute WebM?
+
WEBM.to is built around the container the open web actually chose — VP9 or AV1 with Opus audio, decoded natively by every modern browser and needing no plugin, licence or player. Video is the case where extra round trips hurt most — the files are large and every upload costs real minutes. Running Mute WebM on the same pipeline as the conversions means one upload covers the whole job instead of one upload per tool.
What should I do with the result once Mute WebM is finished?
+
The converter on this site moves video between WebM, MP4, MKV, MOV and the rest, or pulls the soundtrack out entirely, without another upload. Sequencing it that way matters more for video than anywhere else: each re-encode is another generation, so the fewer of them stand between the source and the file you publish, the better it looks.
Is Mute WebM here the same tool the sibling sites run?
+
The engines are shared — the same ffmpeg build with x264, x265 and libvpx, the same workers, the same limits. What a WebM site adds is a view on containers and codecs: which combinations play everywhere, which need a re-encode and which can simply be copied across. It also starts from one fact about the format this site is named after: WebM is VP9 or AV1 with Opus audio, which browsers decode natively but which most desktop editors still transcode on import.
Do I need an account, and does anything get kept?
+
No account is needed. Uploads and results are kept for about 24 hours, which leaves time to download the result, and are then deleted automatically; nobody reads, lists or indexes them. Several files in one job need a paid plan.
