Minify CSS for Faster Websites
The CSS Minifier compresses your stylesheets by removing comments, whitespace, and redundant declarations using the battle-tested CSSO optimizer. Smaller CSS means faster downloads, quicker parsing, and better Core Web Vitals — often reducing file size by 20–50%.
Beautify Minified or Messy CSS
Need to read a compressed stylesheet? Switch to Beautify mode to expand minified CSS into clean, consistently indented code that's easy to inspect and edit. It's the perfect companion for debugging production styles.
Private & Instant
Everything runs locally in your browser. Your CSS is never uploaded, so it's safe for proprietary code, and results appear instantly as you type — no servers, no waiting, no limits.
