link preview checker.

See how a page will look when someone shares it on Google, in chat, or on social, and which tags are missing or too long to show. Nothing is stored.

Paste a page address to see how it will look when shared, and which tags are missing.

Reference

What these tags do

og:title: The headline on a shared link. Keep it under about 60 characters so it isn't cut off.
og:description: The line or two under the headline. Aim for 50–160 characters that say what the product does.
og:image: The picture on the card. Use a 1200×630 image (about 1.91:1), served over https and kept small.
twitter:card: Tells X which card layout to use. summary_large_image shows the big picture; without it X may show a plain link.

Platforms read these from the page's <head>. Add them to your layout once and every page you ship gets a proper preview.
