Why minify CSS?
Minified CSS removes all unnecessary characters — spaces, line breaks, comments — without changing how your styles work. This reduces file size by 20–60% and makes pages load faster.
Google PageSpeed Insights flags unminified CSS as a performance issue. Fixing it can improve your Core Web Vitals score and help your pages rank higher.
