Paste a page URL to see the title, description and image it would show when shared on social media or in a chat app link preview — the same og:* and twitter:* meta tags those platforms read.
The page is fetched by a server function (not your browser, which can't read another site's HTML directly due to CORS) — only the extracted title/description/image fields are returned, never the raw page content, cookies or headers.
What are Open Graph and Twitter Card tags?
They're <meta> tags in a page's <head> (og:title, og:description, og:image, twitter:card, etc.) that tell social networks and chat apps what title, description and image to show when a link to that page is shared.
Does this tool see private or internal URLs?
No — the server function that fetches the page blocks URLs that resolve to private, loopback or link-local addresses (including cloud metadata endpoints), and only accepts http/https URLs. It cannot be used to reach internal network resources.
Is the raw page content sent back to my browser?
No — only the extracted title, description and image fields (and a few related tags) are returned. Response headers, cookies and the rest of the page HTML are never forwarded.
Why does a page show no image or description?
The page may not define Open Graph or Twitter Card tags at all, in which case this tool falls back to the plain <title> and meta description when present, or shows nothing for fields that are missing.
