Free meta tag & Open Graph checker

Open Graph tags are <meta property="og:…"> tags in a page's head that tell Facebook, LinkedIn, WhatsApp, Slack, iMessage and others what title, description and image to show when someone shares the link. Without them, platforms guess — often badly.

Usually because there's no og:image tag, the image URL is relative or broken, the server blocks crawlers, or the file is an unsupported format like SVG. The checker loads the image exactly as a social crawler would and tells you which one it is.

1200 × 630 pixels (a 1.91:1 ratio) works everywhere. Anything under 600 × 315 shows as a small thumbnail instead of a large card. Use JPG or PNG and keep it under 1 MB — Facebook rejects files over 8 MB and X over 5 MB.

Mostly no — X falls back to your Open Graph tags. The one you should add is twitter:card set to summary_large_image, otherwise X shows a small card.

Platforms cache previews for days. Run the URL through Facebook's Sharing Debugger or LinkedIn's Post Inspector to force a refresh. This checker always fetches the page live, so it shows the current state.

Aim for a title of 30–60 characters and a description of 70–160. Longer ones get cut off in Google results — put the most important words first.
