Render-Blocking Reduction

CSS is a critical render-blocking resource. Compressing stylesheet size expedites browser CSSOM tree calculation and accelerates First Contentful Paint (FCP).

Zero Unit & Hex Optimization

Smartly strips redundant unit qualifiers (e.g. margin: 0px → margin:0) and compacts six-character hex codes into standard 3-digit equivalents.

Client-Side Privacy Guarantee

All parsing, AST regex stripping, and compression routines execute directly in client browser memory. No stylesheet data ever touches a remote server.
