  2. The minified output updates automatically.
  3. Copy or download the result to use in production.

About this tool

Minified CSS can be significantly smaller than hand-written stylesheets, which means faster downloads and quicker page rendering. This minifier removes comments, collapses whitespace and trims redundant characters — without changing how your styles behave.

Frequently asked questions

Will minifying change how my page looks?
No. The minifier only removes comments and unnecessary whitespace. It does not alter selectors, properties or values.
Should I keep the readable version too?
Yes — always keep your readable source, and use the minified version for production only. Minified CSS is hard to maintain by hand.
