About CSS Minification

CSS minification reduces file size by removing comments, whitespace, and unnecessary characters. It also optimizes hex colors (#AABBCC to #ABC) and removes units from zero values (0px to 0). Smaller CSS files load faster and improve Core Web Vitals scores. All processing happens in your browser.
