The picture of MP4 and MOV videos is copied without re-encoding, so it's nearly instant.
Why use Cutlia for this
One-click mute
Strip the sound entirely — the picture of MP4 and MOV videos is copied untouched.
Partial muting
Silence specific moments like background chatter — or bleep out a swear word.
Lower volume instead
Prefer quieter over silent? Adjust the volume instead of muting.
Private
Processed in your browser — your video is never uploaded.
Frequently asked questions
Does muting reduce video quality?
No. For MP4 and MOV videos the picture is copied as it is — only the sound changes. Other formats are re-encoded once, in high quality: WebM when you export, older ones like AVI or WMV when you open them.
Is my video uploaded to a server?
No. Cutlia processes your video directly in your browser using WebAssembly and your device's hardware. The file never leaves your computer or phone, so it stays completely private.
Is it really free?
Yes. Cutlia is free to use with no account, no trial and no watermark on your export. The site is paid for by the ads on it, and your files never leave your device.
