Does removing audio make a video much smaller?

It helps most on short clips or videos with high-bitrate audio, where the sound track makes up a noticeable share of the file. On long videos, lowering the resolution or bitrate saves more space.

Can I mute a video without uploading it?

Yes. The tool on this page runs in your browser using your device's own video encoder (WebCodecs), so your file never leaves your phone or computer.

What format do I get after removing the sound?

You get a standard MP4 (H.264 video) with no audio track, which plays normally on phones, computers, and messaging apps.
