Minify and compress CSS code to reduce file size
Built & maintained by Pappu Venkata Subbi Reddy, founder of Clacify
Clacify's CSS Minifier removes whitespace, newlines, comments, and unnecessary characters from CSS code to produce the smallest possible file for production deployment. Minified CSS reduces page load time and bandwidth usage — important for Core Web Vitals scores and SEO. Paste your readable CSS and instantly get the compressed version ready to replace your production stylesheet.
Typical CSS minification reduces file size by 20–30% for normal stylesheets and up to 50% for heavily commented or whitespace-rich CSS. For a 100 KB stylesheet, expect 65–80 KB after minification. Further reduction is possible with gzip compression on the server (typically an additional 70–80% reduction).
Yes. Always serve minified CSS in production to reduce file size and page load time. Use your readable (un-minified) CSS during development and run the minifier as part of your build process (via Webpack, Vite, or Parcel). Faster load times improve user experience and Google PageSpeed scores.
