Runs entirely in your browser — your code is never uploaded to a server. Removes comments and unnecessary whitespace, tightens spacing around braces/colons/semicolons/commas, and drops the trailing semicolon before a closing brace — while preserving the exact content of quoted strings (e.g. in content: "..." or url("...")).
