CSS Minifier
Strip comments and extra whitespace from CSS code.
Worth Knowing
Minifying CSS removes the comments, spaces, and line breaks that help humans but cost bandwidth, typically shrinking a stylesheet by a meaningful fraction with zero change to how it renders. Because CSS ignores whitespace, this transformation is completely safe — unlike JavaScript minification, there are no semicolon-insertion traps. It's a standard production step: smaller stylesheets download faster and, since CSS blocks page rendering until it loads, trimming them measurably improves how quickly a page becomes visible.
How to Use
- Paste or type your css into the CSS Minifier above.
