SSL Checker

Q: How do I know if my SSL is working?

If your site loads with https:// and shows a padlock icon, SSL is usually active. This tool confirms the certificate details and validity.

Q: What should I check most often?

The most important checks are expiration date, correct domain coverage (www/subdomains), and whether the certificate is trusted/valid.

Check any website’s SSL certificate in seconds. Enter a domain to verify HTTPS status, certificate issuer, validity dates, and expiration—great for SEO, security audits, and uptime checks. Fast, free, and works on desktop and mobile.

🔐 SSL Checker helps you verify whether a website has a valid SSL/TLS certificate and a secure HTTPS connection. In one quick check, you can view key certificate details such as the issuer, validity period, expiration date, and overall HTTPS status.

SSL (Secure Sockets Layer / TLS) encrypts data between the browser and the server — protecting logins, forms, payments, and personal information. A properly configured certificate also shows the padlock icon and helps websites meet modern security and SEO expectations.

✅ How to Use

🌐 Enter a domain (example: example.com or www.example.com).
🔍 Click Examine SSL to run the check.
📄 Review certificate details: issuer, validity dates, expiration, and HTTPS status.
🔁 Re-check after renewal or server/CDN changes to confirm everything is correct.

🎯 What You Can Do With SSL Checker

🛡️ Confirm a site is secured with HTTPS and a valid certificate.
⏳ Check SSL expiration date to prevent downtime and browser warnings.
🏢 Verify certificate issuer and basic trust signals for client/vendor audits.
🧩 Detect common SSL issues (misconfiguration, missing/incorrect certificate details).
📈 Support SEO & trust: avoid “Not Secure” warnings that reduce conversions.

💡 Tips for Better Results

🔁 Check both example.com and www.example.com — they can have different certificates.
📅 Set a reminder to renew certificates before they expire (ideally 2–4 weeks early).
🧠 If HTTPS works in one browser but fails in another, it can indicate a chain/intermediate certificate issue.
🌍 If you use a CDN (like Cloudflare), confirm SSL mode and certificate coverage for subdomains.
🕵️ For deeper diagnostics (protocols/ciphers), use a full TLS server test — but this tool is perfect for fast checks.
