What the Open Graph Checker does

Enter a URL and this tool fetches the page and extracts its Open Graph (og:), Twitter Card (twitter:) and standard meta tags — the metadata that controls how your link looks when shared on Facebook, LinkedIn, X, Slack, Discord and messaging apps.

How to use it

  1. Enter the full URL of the page you want to inspect.
  2. Click Generate. The page is fetched server-side (cross-origin HTML can't be read in the browser) and its <head> is parsed.
  3. Review the General, Open Graph and Twitter Card tables, plus the raw tags.

The tags that matter most

  • og:title and og:description — the headline and summary in the share preview.
  • og:image — the preview image (aim for 1200×630).
  • og:url and og:type — the canonical URL and content type.
  • twitter:card — summary_large_image gives the big-image layout on X.

Why check Open Graph tags?

Missing or malformed tags mean your links show up with no image, the wrong title, or a truncated description — hurting click-through from social. Because platforms cache aggressively, verifying tags before you share (rather than after) saves you from re-scraping later.

Privacy

The URL is fetched by our server only to read its meta tags and isn't stored. Requests to private or local network addresses are blocked.
