The output

What the generated code looks like

Clean, production-ready CSS — no vendor bloat, no unnecessary declarations.

minified.css

.btn{display:inline-flex;align-items:center;padding:.625rem 1.25rem;background:#0071e3;color:#fff;font-weight:600;border:none;border-radius:8px;cursor:pointer;transition:background .15s}.btn:hover{background:#005bb5}

Minified CSS removes whitespace, comments, and redundant semicolons. The minified version of the example is 73% smaller than the original. Gzip compression on top of minification reduces it further.

Pro tips

Pro tips for better results

★

Minification alone saves 30-70%; gzip saves more

A CSS file minified from 50KB to 30KB compresses further to 8KB with gzip. Both are applied automatically by most web servers and CDNs. Enable gzip (or Brotli) in your server configuration alongside minification.

★

Minify in your build tool, not manually

Use PostCSS with cssnano, Vite's built-in minification, or Webpack css-minimizer-webpack-plugin for automated minification in production builds. Manual minification is for one-off snippets only.

FAQ

Frequently asked questions

No. Minification only removes whitespace and comments. It does not change property values, selector order, or specificity. The resulting CSS is functionally identical to the original.

Yes. CSS variables are treated as regular property values by the minifier and are not modified. calc() expressions inside var() are also preserved.
