Mixed Content Checker Tool Online

Last updated: May 29, 2026

Scan an HTTPS page for insecure HTTP resources that can trigger browser warnings, break trust, and weaken SEO performance.

Enter an HTTPS URL to scan for mixed content:

How the Mixed Content Checker Works

The tool fetches the page HTML and looks for insecure resources that are loaded from HTTP URLs.

HTTPS validation, the checker confirms the tested page is served over HTTPS.
Resource extraction, it scans images, scripts, stylesheets, iframes, video, audio, object tags, and inline CSS url() references.
Insecure URL detection, any resource that starts with http:// is flagged as mixed content.
Grouped reporting, results are shown by resource type so developers can fix the right template or asset path.

Why Mixed Content Matters

HTTPS is only as strong as the resources loaded into the page. Insecure assets can create security warnings and visual breakage.

Trust, users notice browser warnings and broken lock icons.
Security, HTTP scripts and iframes can be tampered with in transit.
Conversion, checkout, lead forms, and booking flows should never show insecure content warnings.
Technical SEO, pair this check with the Security Headers Checker and SSL Certificate Checker.

Mixed Content Fix Table

Issue	Fix
HTTP image URL	Upload the image to HTTPS hosting or update the source URL to https://.
HTTP script	Replace the script with a secure source. Never ignore insecure JavaScript.
HTTP stylesheet	Serve CSS from the same HTTPS domain or a trusted HTTPS CDN.
Old embed code	Replace legacy iframe or object embeds with current HTTPS embed snippets.

Mixed Content Checker: FAQ

What is mixed content?

Mixed content happens when an HTTPS page loads a resource over plain HTTP. Images, scripts, stylesheets, iframes, video sources, and CSS background URLs can all cause mixed content.

Why is mixed content a security risk?

HTTP resources can be intercepted or modified between the server and the browser. That can break trust, expose users to tampering, and reduce browser confidence in the page.

Can mixed content hurt SEO?

Yes. Browser warnings, broken resources, failed scripts, and lower user trust can hurt conversion and page experience. Secure pages are also a baseline expectation for modern SEO.

Does this tool check every file on my site?

No. It checks the single URL you enter and scans the HTML for insecure resource URLs. Run it on templates, landing pages, checkout pages, and blog posts that use different assets.

Why does the tool say HTTP pages are not meaningful?

Mixed content only applies when a secure HTTPS page loads insecure HTTP resources. If the page itself is HTTP, the first fix is to migrate the page to HTTPS.

How do I fix mixed content?

Update resource URLs to https://, host assets securely, replace old third-party embeds, and use redirects from HTTP assets to HTTPS where possible.

Can a browser block mixed content?

Yes. Modern browsers often block active mixed content such as scripts and iframes. Passive resources such as images may still load, but they can trigger warnings.

Does Web Aloha store checked URLs?

No. The tool fetches the URL, scans resource references, returns the result, and does not store page content.
