Minify CSS for WordPress Themes
Reduce the size of custom WordPress theme stylesheets for better PageSpeed scores.
WordPress tips
WordPress child themes often have a style.css with many lines. Minify it here and enqueue the minified version via functions.php for faster loads.
Google PageSpeed Insights flags unminified CSS as a performance issue. Use this tool to produce a clean, minified version to pass the audit.
Plugins like WP Rocket and Autoptimize can minify CSS automatically — but if you're managing CSS manually, this tool does the same job.
Even without a caching plugin, serving a minified CSS file directly reduces parse time on every page view, improving Time to Interactive (TTI).
