What is CSS Minification?

CSS minification is the process of removing all unnecessary characters from CSS source code without changing its functionality. This includes removing white spaces, newlines, comments, and optimizing values. A smaller CSS file means faster page load times and better website performance scores.

What This Tool Removes

Comments — All /* ... */ block comments are stripped.
Whitespace & Newlines — Extra spaces, tabs, and line breaks are removed.
Last Semicolons — The final semicolon before a closing brace } is redundant.
Zero Units — Values like 0px, 0em, 0% are simplified to just 0.
