Your stylesheets are not compressed

What this means for your business

Your CSS stylesheets haven't been compressed to remove spaces, comments, and formatting. Minifying CSS is a quick technical step that can reduce file size by 20–30% at no cost to visual quality.

How to fix it
Easy
15–30 minutes

  1. 1Your CSS files contain extra whitespace, comments, and formatting that makes them human-readable but larger than necessary. Minification removes all of that without changing how the page looks.
  2. 2Run your CSS through a free online minifier like CSS Minifier (cssminifier.com) and replace the file with the output.
  3. 3For ongoing projects, enable automatic minification through your build process or hosting setup so all future CSS is minified automatically.
  4. 4If you use a CDN like Cloudflare, enable "Auto Minify" in the Speed → Optimization settings — it minifies CSS automatically without touching your original files.

On WordPress

WP Rocket, Autoptimize, or LiteSpeed Cache all have CSS minification built in. Enable it with one toggle — the plugin handles minifying and combining CSS automatically.

On Shopify

Shopify minifies theme assets automatically when you publish your theme. If you're editing theme CSS manually, make sure to use .min.css file conventions or let Shopify's build process handle it.

Pro tip: CSS minification is nearly zero-risk and takes minutes to set up with a caching plugin. It's usually worth enabling before investigating more complex performance issues.
