HTTPS Checker
Check whether a site redirects plain http:// to https:// correctly, and scan the page for mixed-content resources still loaded over insecure http://.
Preguntas frecuentes
How is this different from the SSL Certificate Checker?
The SSL Certificate Checker looks at your certificate itself: issuer, validity dates and trust. This tool checks two different things: whether visiting the plain http:// version of your site actually redirects visitors to https://, and whether the https:// page still loads any scripts, images or stylesheets over insecure http://, which browsers block or warn about as mixed content.
Why does a missing HTTP to HTTPS redirect matter?
If an old link, bookmark or search result points to the http:// version of your site and there's no redirect in place, visitors can land on an unencrypted page instead of being sent to the secure version automatically.
What counts as mixed content?
Any resource, a script, image, stylesheet or inline CSS background, loaded over plain http:// from an https:// page. Browsers silently block active mixed content like scripts, and often show a "not fully secure" warning for passive content like images.
Does this check every page on my site?
No, it checks only the single URL you enter. Mixed content can appear on any page, so it's worth spot-checking a few key pages, not just the homepage.
