Check SSL certificate details, expiry date, issuer, and certificate chain for any website instantly. Free online SSL test tool.
An SSL certificate checker is a tool that inspects the SSL/TLS certificate installed on a website. It reveals important details such as the certificate issuer, validity period, domain coverage, encryption protocol, and the full certificate chain. This helps webmasters and security professionals verify that a site is properly secured.
TooliFyra's free SSL checker provides a quick and easy way to test any website's SSL certificate without installing software or running command-line tools.
An expired or misconfigured SSL certificate can cause browser warnings, lose visitor trust, and hurt your SEO rankings. TooliFyra's SSL certificate checker helps you monitor your certificates and catch expiration issues before they impact your users.
Unlike command-line tools like openssl s_client, our web-based SSL checker provides a clean, visual interface that's easy to understand for both developers and non-technical users.
Webmasters: Regularly check SSL certificates to ensure they haven't expired and are properly configured.

TooliFyra's free SSL certificate checker gives you all the information you need in a clean, easy-to-read format. We don't require signups, API keys, or software installations.

An SSL (Secure Sockets Layer) certificate is a digital certificate that encrypts the connection between a web server and a visitor's browser. It enables HTTPS, which protects data in transit and verifies the website's identity.
You should check your SSL certificate at least once a month, or set up automated monitoring. Most certificates expire after 90 days to 1 year, and an expired certificate triggers browser warnings.
This shows how many days remain before the SSL certificate expires. When it reaches zero, browsers will show security warnings to your visitors.
You can only check publicly accessible domains. Internal or localhost certificates require command-line tools like openssl on your local machine.
