Open Graph preview
When someone shares your link on Facebook, LinkedIn, X, Slack or iMessage, the card they see is controlled by a handful of Open Graph and Twitter meta tags in your page head. Those few lines decide whether your link looks like a polished, clickable card or a bare blue URL — and they are one of the most commonly broken parts of a site because they are invisible until someone actually shares.
This tool fetches any public URL server-side and reconstructs the exact card each major platform would render, so you can see your Facebook, X and LinkedIn previews side by side. It also loads your og:image to check its real dimensions and runs a checklist of the tags that matter — og:title, og:description, og:image, og:url, og:type, og:site_name and twitter:card — flagging anything missing or undersized. You can also paste raw tags to preview a card before you ship it. Fix the gaps it finds and every future share of your content will look intentional. For a full picture of how your pages present to search engines and AI, run the complete audit.
Input

How it works
FAQ
Open Graph (og:) meta tags tell Facebook, LinkedIn, Slack and other platforms how to render a link when it is shared: the title, description, image and site name. Without them, platforms guess from your HTML and often produce an ugly or empty card.
Use at least 1200×630 pixels at a 1.91:1 ratio for the large card most platforms display. Smaller images get upscaled and blurry or fall back to a tiny thumbnail. Keep the file under about 5MB and host it at an absolute HTTPS URL.
X/Twitter falls back to Open Graph tags, so at minimum add twitter:card set to summary_large_image to opt into the big image layout. Add twitter:title, twitter:description and twitter:image only if you want different content on X than elsewhere.
Platforms cache scrapes aggressively. After changing tags, re-scrape the URL with the platform debugger (Facebook Sharing Debugger, LinkedIn Post Inspector) to force a refresh. This tool always fetches fresh, so it reflects your current tags immediately.
