Open Graph Inspector

Paste a URL to see its Open Graph, Twitter-card, and SEO meta — with live preview cards for how the link unfurls on Facebook, X, LinkedIn, Slack, and Discord.

What is Open Graph?

The og: meta tags that decide how your link looks when shared.

Open Graph (the og: meta tags) is the protocol that tells Facebook, LinkedIn, Slack, Discord, iMessage and the rest what title, description, and image to show when someone shares your link. Twitter cards (twitter: tags) do the same for X, and JSON-LD structured data feeds Google's rich results. When these are missing or wrong, your links unfurl as a bare URL — which kills click-through.

This tool fetches the page server-side (re-checking every redirect hop and refusing internal addresses, so it can't be turned into an SSRF probe), parses the markup, resolves relative image and canonical URLs, and renders the preview cards each platform would actually show — plus the full tag breakdown and any JSON-LD blocks.

Frequently asked

What is the ideal og:image size?

1200×630 pixels (a 1.91:1 ratio) is the safe default for a large preview card on Facebook, X, LinkedIn and Slack. Use an absolute URL and keep the file under about 5 MB.

I updated my tags but the preview has not changed — why?

Platforms cache scraped metadata aggressively. Force a refresh with the platform's own debugger — for example Facebook's Sharing Debugger or LinkedIn's Post Inspector.

Do I need both Open Graph and Twitter Card tags?

Not strictly — X falls back to Open Graph when Twitter-specific tags are absent. Add twitter:card for a large image, but you don't need to duplicate every tag.
