Compress and optimize your CSS by removing whitespace, comments, and shortening values. Reduce file size for faster websites.
CSS minification removes all unnecessary characters from your stylesheet without affecting how it works in the browser — comments, whitespace, redundant semicolons, and long hex color values are optimized. This reduces the CSS file size, which means browsers download and parse it faster.
Minification modifies the raw CSS source to make it smaller. Compression (like Gzip or Brotli) is an additional step applied by your web server. You should do both: minify first, then let your server compress the already-minified file for maximum performance.
