What is CSS Compressor?

CSS Compressor is a free, browser-based CSS minifier that reduces the size of your CSS files instantly. Smaller files mean faster page loads and better SEO scores.

Remove comments — strips /* block comments */ while preserving licence blocks (/*!).
Strip whitespace — collapses spaces, tabs, and newlines around selectors, properties, and values.
Remove last semicolon — drops the trailing ; before each closing } brace.
Shorten zero values — converts 0px, 0em, 0rem, 0% to bare 0.
Shorten colors — converts #aabbcc hex colors to #abc shorthand where possible.
Normalize none/0 — converts border: none to border:0 and similar optimizations.
Beautify / Format — pretty-prints minified CSS back into readable, indented form.

All processing happens entirely in your browser. Your code is never sent to any server.
