What is CSS Minify?
Paste CSS and get it minified instantly — comments and whitespace stripped, output shrunk for production without changing what the styles do. Smaller CSS means a faster first paint, especially on a mobile connection where every kilobyte in the critical render path costs load time. Minification here runs entirely in your browser, so you can shrink a stylesheet before committing it without sending your source to a third-party service.
