HTTP Headers & Compression Optimization Guide
This tool analyzes HTTP response headers, status codes, and server configurations. It also tests website compression (Gzip and Brotli) to ensure optimal loading speeds and verifies the presence of critical security headers like HSTS, CSP, and X-Frame-Options.
What are HTTP Headers?
HTTP headers are hidden key-value pairs exchanged between a browser and a server. They contain crucial instructions about security policies, cache, and redirect rules.
Why is Gzip or Brotli compression important?
Enabling compression (like Gzip or Brotli) on your web server reduces the size of your HTML, CSS, and JS files by up to 80%. This drastically improves page load speed.
Gzip vs Brotli: Which is better?
Brotli is a newer compression algorithm developed by Google. It generally offers 15-20% better compression ratios than Gzip.
How do I check if my website has missing security headers?
Using our HTTP headers checker, you can instantly see your site's full header response including HSTS, CSP, X-Frame-Options, and more. Missing headers can expose your users to common web vulnerabilities.
