Critical CSS Generator

Extract critical above-the-fold CSS for faster page loads

About Critical CSS

Critical CSS is the minimum CSS needed to render the above-the-fold content. By inlining critical CSS and deferring the rest, you can improve initial page load time and Core Web Vitals scores.

Best Practices

  • • Inline critical CSS directly in the <head> tag
  • • Load the full CSS asynchronously using preload
  • • Keep critical CSS under 14KB (first TCP packet)
  • • Update critical CSS when your above-the-fold design changes
  • • Test on different viewport sizes
