About CSS Minifier

Updated Jan 2025

The CSS Minifier removes all unnecessary whitespace, comments, and redundant declarations from CSS code, producing the smallest valid stylesheet. This reduces file size, improving page load times. The minified output is fully valid CSS that browsers parse identically to the original.
