HTTP/2 Support Test

Test whether a website supports the HTTP/2 protocol for improved performance and efficiency. HTTP/2 offers significant advantages over HTTP/1.1 including multiplexing, header compression, and reduced latency.

Enter a website URL to test HTTP/2 protocol support. HTTPS URLs are recommended for the best HTTP/2 experience.
About HTTP/2

HTTP/2 is a major revision of the HTTP network protocol that brings significant performance improvements over HTTP/1.1:

Performance Benefits:
  • Multiplexing: Multiple requests over a single connection
  • Header Compression: Reduces overhead with HPACK compression
  • Server Push: Proactive delivery of resources
  • Binary Protocol: More efficient than text-based HTTP/1.1
Why It Matters:
  • Faster page load times
  • Reduced server resource usage
  • Better mobile performance
  • Improved user experience
Educational Note: HTTP/2 requires TLS (HTTPS) in most browsers for security. Modern web servers like nginx, Apache, and CDNs typically support HTTP/2 when properly configured. Testing HTTP/2 support helps ensure your website delivers optimal performance to users.
