Enable text-based compression

Compressed assets download faster, reducing the time to first paint and improving the overall perceived performance, especially on slower mobile networks.

Quick Reference

• Use Gzip or Brotli to compress text resources (HTML, JS, CSS)
• Brotli provides superior compression for modern browsers
• Significantly reduces data transfer size and load times
• Compression helps network cost, but it does not remove parse and execution cost from oversized bundles

Check

Verify that text-based resources are served with Content-Encoding: gzip or br headers.

Fix

Enable Gzip or Brotli compression in your web server (Nginx, Apache) or CDN settings.
