CSS Minifier

CSS comments (/* ... */) and extra blank lines, while correctly leaving comment-like text inside strings (e.g. in content: or url()) untouched.

No — it only removes comments and blank lines, never touches selectors, properties, or values, so the rendered styles are unchanged.

A fully aggressive CSS minifier also merges rules and shortens values, which requires a real parser to do safely. For maximum compression in production, a build-time tool like cssnano is the safer choice — this tool is for quick, safe cleanup.
