Open Graph & Social Card Checker

See exactly how any page looks when shared on X, LinkedIn, Facebook and WhatsApp — Open Graph tags, Twitter cards and the image crawlers actually see. Free, no signup.

What Open Graph tags control

When someone shares your page on LinkedIn, X, Facebook, WhatsApp or Slack, the platform doesn't render your page — it renders your Open Graph tags. No og:image means a bare text link that gets a fraction of the clicks. This tool fetches any URL, extracts the Open Graph and Twitter card tags exactly as scrapers see them, and renders the share card so you know what people get before you post.

Getting the card right

Use a 1200×630 image (1.91:1) with the critical content centered, set og:title and og:description explicitly rather than trusting fallbacks, and add twitter:card = summary_large_image for the large format on X. Remember platforms cache aggressively — after a fix, re-scrape with the platform's debugger. Check the search-facing half of the same metadata with the meta tag checker.

Frequently asked questions

1200×630 pixels (1.91:1). That renders sharp on every major platform. Keep critical text inside the center safe area — some platforms crop toward a square.

Platforms cache previews aggressively. After fixing your og:image, re-scrape with the platform's debugger (e.g. LinkedIn Post Inspector) or share the URL with a query string appended to bust the cache.
