Free HTTPS & Mixed Content Checker
Enter a URL to check if it's served over HTTPS and whether any resources (images, scripts, stylesheets) are loaded over insecure HTTP.
How it works
This tool checks two things: whether your page is served over HTTPS, and whether any resources on the page (images, scripts, iframes, stylesheets) are loaded over plain HTTP. Mixed content can trigger browser warnings, break page functionality, and signal to search engines that your site isn't fully secure.
External links using HTTP are not flagged — only resource-loading tags that actually embed insecure content into your page.
