SSL Certificate Checker

Check HTTPS availability, secure connection status, redirect behavior, and browser-accessible SSL signals.

Browsers do not expose full SSL certificate details like issuer and expiration date to client-side JavaScript. This tool performs browser-compatible HTTPS checks. For full certificate expiry checks, connect this page to a small server-side SSL API.

Free SSL Checker

Use this free SSL checker to test whether a website is available over HTTPS, whether the browser can establish a secure connection, and whether the URL responds successfully.

Important Limitation

A true SSL certificate checker needs server-side code to inspect certificate issuer, expiration date, SAN names, and chain validity. This browser-based version is useful for quick HTTPS troubleshooting.
