How to use Open Graph Preview

Preview exactly how your URL will appear when shared on Facebook, Twitter/X, LinkedIn, WhatsApp, Slack, Discord, and iMessage — using the actual Open Graph and Twitter Card metadata from your page. Enter any URL to fetch and render its og:title, og:description, og:image, and card layout in a pixel-accurate social share preview. Essential for checking link previews before publishing or launching.

  1. Enter the full URL of the page you want to preview (include https://).
  2. The tool fetches the page's Open Graph tags via a proxy (to handle CORS).
  3. Select the platform to see platform-specific card rendering (Facebook link post, Twitter summary card, etc.).
  4. Review each field: og:title, og:description, og:image size and crop.
  5. If the preview is wrong, edit the metadata using the og:tags generator tool.

Your data never leaves your device — 100% private processing.

How Open Graph metadata works

Open Graph (OG) is a protocol developed by Facebook that lets web pages define how they appear in social shares. When you paste a URL on Facebook, LinkedIn, Twitter, or any OG-aware platform, the platform fetches the URL and reads <meta property="og:..."> tags from the HTML. Key tags: og:title (the headline), og:description (the summary text), og:image (the preview image — recommended 1200×630 for most platforms), og:url (canonical URL), og:type (website, article, video). Twitter additionally supports its own twitter:card, twitter:title, twitter:description, and twitter:image tags that override OG when present.

TagRecommended valueNotes
og:title40–60 charactersTruncated on mobile at ~55 chars
og:description100–155 charactersShown on desktop, often hidden on mobile
og:image1200×630 px, < 1MBJPG or PNG; must be publicly accessible
og:image:altDescribe the imageAccessibility requirement
og:typewebsite or articleAffects how Facebook structures the card

Debugging missing or wrong previews

If a social platform shows a wrong preview (old image, incorrect title), it's usually a caching issue — platforms cache OG metadata for hours or days. Use the platform's official cache-clearing tool: Facebook's Sharing Debugger (developers.facebook.com/tools/debug), LinkedIn Post Inspector (linkedin.com/post-inspector), or Twitter Card Validator (cards-dev.twitter.com/validator). These tools force a fresh fetch of your URL. For Next.js sites, ensure OG image routes return proper Cache-Control headers and that og:image uses an absolute URL, not a relative path.
