About this tool

Compress CSS by removing comments and whitespace around symbols, running fully in your browser.

What gets removed?

Comments, redundant whitespace, spaces around braces, colons, semicolons and commas, and the last semicolon before a closing brace.

Is the result equivalent CSS?

Yes — it only removes insignificant characters, so the styling behavior stays the same.
