Find Every Insecure Resource

Scans your page for HTTP images, scripts, iframes, and stylesheets that break the padlock and trigger browser warnings.

Protect Rankings and Trust

Mixed content warnings scare visitors away and can hurt SEO. Catch issues before they cost you clicks and conversions.

Clear Fixes, Not Jargon

Each finding comes with a plain-language recommendation, so you know exactly which URLs to update to HTTPS and where.

A mixed content checker finds insecure HTTP resources loaded by an otherwise HTTPS page. You enter a URL and it scans for images, scripts, stylesheets, and other assets requested over plain HTTP. These insecure references break the padlock, trigger browser warnings, and can block scripts entirely, so the tool pinpoints each offending resource for you to fix.

What insecure resources the checker finds

The checker loads your secure page and inspects every request it makes, flagging any asset still pulled over HTTP. It separates active mixed content like scripts, stylesheets, and iframes, which browsers often block outright, from passive content like images, audio, and video, which browsers usually allow but mark as insecure. It lists the exact resource URLs and where they are referenced, whether in your HTML, inline styles, or third-party embeds. It also catches hardcoded HTTP links that survived an HTTPS migration. The result is a precise inventory of what is undermining your page security rather than a vague warning that something is wrong.

How to fix mixed content warnings

Work through the flagged resources and update each insecure reference. Where the same asset is available over HTTPS, simply change the URL protocol or use a protocol-relative path so it inherits the page scheme. For assets on servers that lack HTTPS, host the file yourself or switch to a provider that supports encryption. Update hardcoded links in templates, stylesheets, and your database left over from an HTTP era. A Content-Security-Policy with upgrade-insecure-requests can catch stragglers during migration. Recheck the page afterward to confirm the padlock is intact and no request falls back to HTTP, including assets loaded by third-party scripts.

Why mixed content hurts trust and SEO

Mixed content breaks the promise of a secure page, and browsers respond by hiding the padlock, showing not-secure warnings, or blocking active resources so features silently fail. Those warnings scare visitors and raise bounce rates, while blocked scripts and styles can leave pages broken for real users and crawlers alike. Because full HTTPS is a ranking and trust signal, a page riddled with insecure requests undercuts the security you migrated to achieve. Clearing mixed content restores a clean secure state, keeps functionality intact, and protects the credibility that both users and search engines expect from an encrypted site.

Frequently Asked Questions

What is mixed content?

Mixed content happens when a page served over HTTPS loads resources like images, scripts, or stylesheets over plain HTTP. Browsers may block those resources or show security warnings, which erodes visitor trust.

Does mixed content affect SEO?

Yes, it can. HTTPS is a ranking signal, and modern browsers in 2026 block insecure scripts outright, which can break pages and drive visitors away. Fixing mixed content protects both user experience and the trust signals search engines rely on.

Is the Mixed Content Checker free?

Yes. The Mixed Content Checker is free once you create a Brainito account. Enter your URL, and the tool scans the page and returns every insecure resource it finds, along with clear recommendations to fix each one.
