CSS Minifier
Minify pasted CSS by removing comments and unnecessary whitespace.
Shrink CSS for production
Minified CSS loads faster because every unnecessary space, line break, and comment is stripped. This minifier collapses pasted CSS to a compact form you can ship, without touching what the styles actually do.
It is handy for one-off files, inline critical CSS, and snippets that never pass through a build pipeline. Paste your stylesheet, get the minified version, and copy it — the smaller payload means a quicker download for every visitor.
Private and instant
Everything runs locally in your browser using standard web APIs — nothing is uploaded, logged, or stored on any server — so the tool works offline, responds instantly, and keeps whatever you paste in on your own device. That makes it safe to use even for confidential, client, or internal data you would never send to an unknown website.
