Free open graph debugger and checker. Paste a URL to preview link cards on Facebook, X, LinkedIn, Slack, Discord, and WhatsApp, then fix a weak image.
This checker reads og:title, og:description, og:image, and the Twitter card tags, then previews the unfurl on Facebook, X, LinkedIn, Slack, Discord, and WhatsApp. A missing or tiny image is the usual reason a link looks unfinished. Generate a replacement, or publish the same image with the API or MCP, then run the URL again. Carrd sites upload the file under Publish β Media. The Carrd social image guide walks through that step.
Build a 1200Γ630 replacement for the URL you just checked.
Return that image from your app instead of uploading a file by hand.
Ask an agent to generate the preview from the same public URL.
Write og:image and Twitter cards for posts, pages, and WooCommerce.
What does "OG" mean?
"OG" stands for Open Graph, a metadata standard that tells social platforms how to render link previews. The protocol was introduced by Facebook and is now recognized by most platforms (LinkedIn, X/Twitter, Slack, Discord, WhatsApp, iMessage, and more).
What is an Open Graph image?
It's the image referenced by the og:image meta tag (and twitter:image for Twitter Cards) that appears in link previews when your URL is shared.
<meta property="og:title" content="Your Page Title" />
<meta property="og:description" content="Short, compelling summary." />
<meta property="og:image" content="https://example.com/og-image.jpg" />
<meta name="twitter:card" content="summary_large_image" />
<meta name="twitter:image" content="https://example.com/og-image.jpg" />Is this a replacement for the Twitter Card Validator?
Yes. X retired the Card Validator's preview feature, so you can no longer test cards there. Paste your URL above to see how your Twitter Card renders, including summary_large_image layouts, plus previews for Facebook, LinkedIn, Slack, Discord, and WhatsApp.
