# How to use the free mixed content checker

> Scan any HTTPS page for insecure http:// resources (images, scripts, iframes) that break the padlock.

## Quick answer

 Enter your HTTPS page URL at /tools/mixed-content-checker. It renders the page, catches every http:// request, and shows the exact file and line to fix.

## What it checks

- Insecure images, scripts, iframes, and stylesheets

- Passive vs active mixed content (severity)

- Sub-resources loaded by third-party scripts

- Broken padlock indicators in modern browsers

- URL-level fix suggestions (usually swap to //)

## Where to find it in Lemwatch

 Public tool: **/tools/mixed-content-checker**. Use it after a WordPress migration or when moving to HTTPS.

## How to use it

- Paste the HTTPS URL of the page.

- Click Scan .

- Review flagged resources grouped by severity.

- Update each URL to https:// (or protocol-relative // ).

- Re-scan to confirm zero mixed content remains.

## FAQ

### Why does the tool show more resources than my dev tools?

 It follows lazy-loaded assets and iframe-embedded scripts that Chrome hides by default.

### Will fixing mixed content improve SEO?

 Yes — Chrome downgrades mixed HTTPS pages, and Search Console reports them as security issues.
