WP Super Minify automatically minifies, compresses, and caches HTML, CSS & JavaScript files (inline and individual) on demand to enhance website’s load speed.
Once activated, the plugin seamlessly compresses HTML, inline CSS, and JavaScript, reducing file sizes for faster page loading. This optimisation helps improve your site’s Google PageSpeed Insights and GTmetrix performance scores.
Additionally, WP Super Minify minifies individual JavaScript and CSS files, ensuring they load correctly and are automatically updated whenever the original files are modified or added — no manual settings needed!
Optimise your website effortlessly and deliver a faster, smoother experience to your visitors.
