Why Minify Your CSS?
Minified CSS loads faster because it removes comments, whitespace, and redundant characters without changing functionality. Smaller CSS files mean faster page loads, better Core Web Vitals scores, and improved SEO rankings.
This tool processes everything in your browser — no data is sent to any server. It removes block comments (/* */), trims whitespace around selectors and properties, collapses multiple spaces, and strips trailing semicolons before closing braces.
