OG image checker

Paste a URL. We fetch the HTML (public http(s) only), preview how the card may look on Facebook, X, LinkedIn, WhatsApp, and Discord, and score the tags. These are mocks from the tags we saw — not live scrapes from each network.

Checker questions

What this tool does — and what it does not.

Does the OG image checker use Facebook or LinkedIn?

No. We fetch your public HTML, read the tags, and draw CSS mockups. Use Facebook Sharing Debugger or LinkedIn Post Inspector to refresh those networks’ caches.

Why did a check fail for twitter:card?

X shows a large image only when twitter:card is summary_large_image. og:image alone is not enough. See the Twitter card image guide from the ? on that row.

Can you inspect localhost or a private site?

No. Only public http(s) URLs. Loopback, private, and link-local addresses are rejected (SSRF guard). Deploy or tunnel first.
