SSL Checker
Check whether a website loads over secure HTTPS and how to verify its certificate in your browser — free, fast and private.
How to use SSL Checker
- Enter a website domain without https://.
- Click Check SSL / HTTPS.
- Read whether the site loads over HTTPS.
- For full certificate details (issuer, expiry), click the padlock in your browser’s address bar — browsers do not let web pages read certificate details.
Honest limit: browsers do not let a web page read another site’s SSL certificate (issuer, expiry). This tool only checks whether the site loads over HTTPS and tells you how to see the full certificate via your browser’s padlock icon — it never invents certificate details.
Frequently Asked Questions
Why can’t this tool show the certificate expiry date?
Browsers do not let a web page read another site’s certificate details, so no honest browser-only tool can show the expiry or issuer. Use the padlock icon in your browser’s address bar for full certificate details.
