How to Enable SSL and HTTPS in Webflow

Learn how to enable and verify SSL (HTTPS) on your Webflow site: automatic certificate and mixed content.

In this tutorial, Sandro, co-founder of the Gemeos Webflow agency, shows you how to enable and check SSL (HTTPS) on your Webflow site.

Cloudflare proxy activeMay block itSwitch the proxy to DNS only mode

SSL is automatic in Webflow

Webflow automatically generates a Let's Encrypt SSL certificate for every connected domain. You don't need to configure anything manually. HTTPS is enabled within minutes of DNS validation.

1. Check the SSL status

In Publishing > Custom Domains, each domain shows its SSL status: a green icon means the certificate is active. If the status is pending, wait up to 24 hours after the DNS connection.

2. Force HTTP to HTTPS redirects

In Project Settings > Publishing, enable the SSL option to force all http:// URLs to redirect to https://. This option is enabled by default on new projects.

3. Fix mixed content issues

If your site shows a crossed-out padlock icon, you have mixed content: resources loaded over HTTP on an HTTPS page. Check the Chrome console (F12) to identify the insecure URLs and replace them with their HTTPS versions.

good to know

The Webflow SSL certificate (Let's Encrypt) is renewed automatically every 90 days. You don't have to manage the renewal. On the other hand, if you move your domain to another host, your Webflow SSL certificate won't follow — you'll need to generate a new one with the new host.

Conclusion

Webflow SSL is fully managed, with no manual intervention.
