Bulk up to 100 • Detect weak HTTPS enforcement

HTTP to HTTPS Checker

Paste domains or URLs — we’ll test both http and https versions, follow redirects, and show whether HTTP cleanly upgrades to HTTPS.

Paste up to 100 domains/URLs (one per line)
Tip: we keep your path/query (e.g. /page?x=1) when testing. Default scheme is https for parsing.

Results

Domain State HTTP result HTTPS result
Run a check to see results here.
Goal: HTTP should end on an https:// final URL with minimal hops.

What a “correct” setup looks like

You want HTTP to permanently redirect to HTTPS (usually 301) and HTTPS to load with a 2xx.

  • OK HTTP final URL uses HTTPS
  • Warning HTTP serves content (no upgrade), long chains
  • Error timeouts, loops, 4xx/5xx, HTTPS unreachable

HTTP to HTTPS Checker: confirm secure redirects in seconds

This tool checks whether your site upgrades visitors and bots from http to https. Paste up to 100 domains or URLs, and we’ll test both protocols, follow redirects, and show the final destination and status codes.

How the checker works

For each input, we build two test URLs: one with http:// and one with https://, preserving the path and query if you provided them. Then we follow redirects hop-by-hop, record the initial and final status codes, the final URL, and request timing.

Why HTTP → HTTPS matters for SEO

If your site still serves content on HTTP, search engines may crawl duplicate versions, split signals, and waste crawl budget. The safe baseline is simple: always redirect HTTP to HTTPS with a permanent redirect (usually 301) in one hop, and ensure the HTTPS version returns a clean 2xx.

Common problems you’ll detect

  • No redirect: HTTP returns 2xx and serves content.
  • Wrong destination: HTTP redirects but final URL is still HTTP.
  • Chains: too many hops slow crawling and increase failure risk.
  • HTTPS broken: HTTPS unreachable or returns 4xx/5xx.
  • Loops/timeouts: misconfigured rules or CDN conflicts.

Fast workflow tip

Test the homepage plus a deep page URL. Your job is to confirm one fact: does HTTP consistently land on HTTPS, quickly, without chains or errors. Export results during audits to hand off a clean fix list to devs.

FAQ

What does this HTTP → HTTPS checker actually test?

For every input, the tool builds two URLs: http:// and https://. If you provided a path/query (for example /page?x=1), it keeps it. Then it follows redirects hop-by-hop and reports initial status, final status, final URL, hop count, and timing for both protocols.

What is the “correct” HTTPS enforcement result?

The ideal result is simple: HTTP ends on an HTTPS final URL in one hop (usually a 301), and the HTTPS version returns 2xx. Anything else is either a warning or a problem.

What do the states mean: “Redirects to HTTPS”, “HTTP serves”, “Redirects (not https)”, “HTTP fail”?

Redirects to HTTPS means HTTP ends at an https:// final URL (good).
HTTP serves means the site still serves content on http:// (bad for enforcement).
Redirects (not https) means HTTP redirects, but the final destination is still not HTTPS (misconfiguration).
HTTP fail means the HTTP request did not complete (timeout/DNS/blocked).

What status code should HTTP → HTTPS redirect use?

Usually a permanent redirect (301, sometimes 308). Temporary redirects (302/307) are typically not what you want for long-term HTTPS canonicalization.

Is one redirect hop acceptable?

Yes — one hop is normal (HTTP → HTTPS). Problems start when you chain redirects (HTTP → WWW → HTTPS → trailing slash → …). Reduce hops for speed and reliability.

Why do I see “no https redirect” or “final not https” in issues?

That means HTTP is not cleanly upgrading to HTTPS. Either it serves a 2xx on HTTP, or it redirects but ends somewhere that is still not https://. You want the final destination to be HTTPS consistently for every tested path.

Why do I see status code 0?

Status 0 means the request didn’t complete (DNS failure, TLS handshake error, firewall/CDN block, or timeout). It’s not an HTTP response — it’s a transport-level failure.

Does HTTPS need to work even if HTTP redirects?

Absolutely. If HTTP redirects to HTTPS but HTTPS returns errors or is unreachable, users and bots still fail. This tool tests HTTPS directly to catch that.

Can CDN rules affect HTTP → HTTPS behavior?

Yes. Many redirect problems come from conflicts between CDN settings (for example Cloudflare “Always Use HTTPS”) and origin server rules. Always retest after changing CDN redirect/SSL settings.

Why can HTTP redirect to HTTPS, but the tool still flags “https broken”?

Because redirecting is not enough. If the HTTPS endpoint returns 4xx/5xx, has certificate/TLS issues, or is blocked, the final experience is still broken. The checker flags that because bots/users end up failing on HTTPS anyway.
