About this tool

Minify CSS by removing whitespace, comments, and unnecessary characters to reduce file size. Our CSS Minifier strips all comments (/* */), collapses whitespace, removes unnecessary semicolons before closing braces, and trims the output. The tool shows original size, minified size, and percentage savings — typical CSS files can be reduced by 20-40% through minification alone. Minified CSS loads faster, reduces bandwidth usage, and improves Core Web Vitals scores. For production websites, combine minification with gzip/brotli compression for maximum performance. Note: always keep your unminified source files for development — minify only for production deployment.
