What is CSS minification?

CSS minification removes whitespace, comments, and unnecessary characters from CSS code to reduce file size and improve page load speed.

Does minification change my CSS behavior?

No. Minification only removes formatting — it doesn't change how your CSS works. The minified version produces identical visual results.

How much file size can I save?

Typically 20-40% reduction depending on the original formatting. Heavily commented files may see even greater savings.

About CSS Minification

CSS minification removes unnecessary characters like whitespace, comments, and semicolons to reduce file size. Smaller CSS files load faster, improving website performance and user experience. Use beautify mode to make minified CSS readable again.
