1Upload the videos whose soundtrack you want gone.
2Confirm that you want the audio track dropped entirely rather than turned down to silence.
3Run it — the track is removed at the container level and the picture is copied through untouched, so it finishes in seconds.
4Download the silent Video file, which is also smaller than what you started with.
Mute Video FAQ
Does the container format matter?
+
It does. this format is read and written by the same streaming pipeline as everything else we support. That governs how the tracks are stored and therefore how cleanly one can be dropped.
Anything specific to Video worth knowing?
+
Yes — the container and codec are probed before anything runs, so mixed uploads in one batch are handled per file. Relevant when the source has more than one audio track.
How does Mute Video remove the sound?
+
Concretely, the audio track is removed at the container level and the picture is stream-copied, so the job finishes in seconds whatever the clip length. The result is the same picture with no audio track at all, rather than an audio track turned down to zero.
Is the video re-encoded when I mute it?
+
No. Removing a track is a container operation, so the video stream is copied through bit-identically and the job finishes in seconds regardless of how long the clip is.
What happens to audio, subtitle and chapter tracks?
+
They are carried across wherever the target container can hold them, including multiple audio languages, embedded subtitles and chapter markers, rather than silently keeping only the first track of each.
Which video formats does Mute Video accept?
+
MP4, MOV, MKV, WebM, AVI, WMV, FLV, 3GP, M4V, MPEG and MPG. Each file is probed for its real container and codec before anything runs, so a mixed batch is handled correctly file by file.
Is there a file size limit on Mute Video?
+
Yes: free accounts process video up to 1 GiB per file whichever container you brought; ffmpeg with x264, x265 and libvpx does the encoding. It is high enough that upload speed is usually the binding constraint rather than the cap itself.
Will Mute Video lower the quality of my videos?
+
Only if the operation requires re-drawing frames. Container-level and timeline-level work is done as a stream copy, which is bit-identical to the source and finishes in seconds. Anything that must re-encode does so at a quality level you choose.
Why would a modern-format site run Mute Video?
+
WEBP.to is built around the modern replacement for both of the old defaults: one format that does lossy, lossless, alpha and animation, and reliably lands smaller than the JPEG or PNG it came from. People arrive here having decided the old defaults are costing them bandwidth, and that decision immediately raises the rest: what size, what quality, what happens to the transparency. Mute Video is on the same upload and the same account so those questions get answered in one place.
Once Mute Video has run, what is worth doing next?
+
The converter on this site moves images to and from WebP, PNG, JPG and AVIF, which is where you decide whether a smaller file is worth losing the older browsers. Doing it in that order matters: pick the pixels first and the container afterwards, because the container is the cheap decision and the pixels are the expensive one.
Do the sibling sites run something different?
+
The engines are identical — same libraries, same workers, same caps. What is different is the opinion attached, and the opinion here rests on a property of the format this site is named after: the same .webp extension can hold a lossy VP8 frame, a lossless one, or an animation, so the sensible processing path is decided per file rather than per extension.
What happens to my file, and is an account required?
+
No account, and nothing is retained: uploads are deleted from the workers shortly after the job finishes, and nothing is inspected, listed or indexed. Accounts exist for history and batch size only.
