Mixed Content Checker finds insecure HTTP resources loaded on HTTPS pages. Even one HTTP image or script on an HTTPS page triggers browser warnings and can break the padlock icon. This tool scans your page and lists every insecure resource that needs fixing.
How to use this tool
Enter your HTTPS URL.
The tool fetches the page and scans all resource references.
Review the list of HTTP resources found (images, scripts, stylesheets, fonts).
Update each resource URL from http:// to https:// or use protocol-relative //.
Re-scan after fixing to confirm the page is fully secure.
Frequently asked questions
What is mixed content?
When an HTTPS page loads resources (images, scripts, CSS) over HTTP. Browsers block active mixed content (scripts) entirely and warn about passive mixed content (images). Both hurt user trust.
How does mixed content affect SEO?
Google expects HTTPS pages to be fully secure. Mixed content can prevent the padlock icon, reduce trust signals, and potentially affect rankings. Chrome actively warns users about insecure resources.
How do I fix mixed content?
Change resource URLs from http:// to https://. If the resource host doesn't support HTTPS, host it yourself or find an alternative. Use Content-Security-Policy headers to detect issues automatically.
Can mixed content break my site?
Active mixed content (JavaScript, CSS) is blocked by browsers, which can break functionality and layout. Passive content (images) shows warnings but still loads. Both should be fixed.
