Open Graph Checker & Debugger

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.

Why should you care about a high-quality Open Graph image?

• Higher click-through rates from social shares.
• Stronger brand recognition and consistency.
• Better readability and accessibility across light/dark UIs.

Quick tips

• Use 1200×630 (1.91:1), PNG or high-quality JPEG. This is the recommended size for most platforms.
• Keep text large and high-contrast; avoid clutter.
• Ensure the brand mark/logo is present and clear.

How do I clear cached previews?

Social networks cache preview images. After updating your meta tags, you need to clear their caches:

• Facebook: Use Facebook's Sharing Debugger and click "Scrape Again"
• LinkedIn: Use LinkedIn's Post Inspector to refresh the cache
• X (Twitter): X retired its Card Validator, and there is no public refresh tool. The cache usually expires within about a week.
• Universal trick: change the image URL (for example, add ?v=2) to force every platform to fetch it fresh
