HTTP/2 Checker – Free Online Tool
Our free HTTP/2 Checker tells you whether a website is served over HTTP/2, the modern protocol that makes pages load faster.
What is HTTP/2 Checker?
HTTP/2 is a major upgrade to the HTTP protocol. It allows many files to download at the same time over a single connection (multiplexing), compresses headers and reduces delays compared with the older HTTP/1.1.
Most modern hosts support HTTP/2 with HTTPS, but misconfigured servers and old hosting plans may still use HTTP/1.1.
How to use the HTTP/2 Checker
- Enter the domain or URL.
- Click check.
- See whether HTTP/2 is supported.
- If not, ask your host to enable it or consider a CDN.
Common use cases
- Checking hosting performance features
- Improving page speed and Core Web Vitals
- Comparing hosting providers
- Verifying CDN configuration
