HTTP vs HTTPS

Side-by-side comparison, when-to-use-each guide, and instant conversion. Reviewed for 2026.

Quick answer: HTTPS is HTTP encrypted with TLS. Modern browsers (Chrome 68+, 2018) mark HTTP sites as 'Not secure'. Google has ranked HTTPS over HTTP since 2014. As of 2026, ~95% of all browser traffic is HTTPS. There's no good reason to serve a new site over HTTP.

Frequently asked

?

Do small/personal sites really need HTTPS?

Yes. Browsers actively warn users about HTTP sites. Search engines downrank them. There's zero cost and one-click setup on Cloudflare or Let's Encrypt. There's no scenario in 2026 where HTTP is the right choice for a public site.

?

Is HTTP/3 different?

HTTP/3 is the protocol version, not the security layer. HTTP/3 runs over QUIC (UDP-based) instead of TCP. It's always encrypted. Mainstream browser support since 2022.
