Open Graph Checker

The Open Graph Checker generates a visual preview card and the exact <meta> tag HTML you need to control how your page appears when shared on Facebook, Twitter/X, LinkedIn, and other platforms. Paste in your OG metadata values, instantly see the social card preview, and copy the ready-to-paste HTML head tags. Built for developers and SEO engineers who need to test and ship OG tags without third-party tools or browser extensions.

How to Use

1. Configure your page title, description, image URL, and canonical URL in the Content fields. 2. Adjust the card layout style, accent color, and border radius to match your design preferences for the preview card. 3. Preview the rendered social share card — it shows exactly how your page will appear on LinkedIn, Facebook, and Twitter/X. 4. Copy the generated <meta> tag HTML block from the output and paste it inside the <head> of your page.

Why Use This Tool?

Manually writing and validating Open Graph tags is error-prone — a missing og:type or malformed image URL silently breaks social previews on every platform. This tool generates the full, spec-compliant meta tag block in seconds and shows a live visual card so you catch problems before deploying. No browser extension, no third-party API call, no account needed — just paste your values and ship.

Frequently Asked Questions

What is the Open Graph Checker?

It's a free tool that lets you input your page's Open Graph metadata and instantly generates both a visual social-share card preview and the production-ready HTML <meta> tags to paste into your page's <head>.

Which platforms use Open Graph tags?

Facebook, LinkedIn, Slack, Discord, WhatsApp, and most chat and social platforms read og:title, og:description, og:image, and og:url. Twitter/X uses its own twitter:card tags but also falls back to OG tags — this tool generates both sets simultaneously so you're covered everywhere.

Is it free?

Yes — the Open Graph Checker is completely free with no signup required. Built by the CanvasBuilder.co team.
