About this tool

Open Graph and Twitter Card tags control how links look on Facebook, LinkedIn, Slack, and X when shared. Preview image, title, and description before posting.

Missing og:image often yields bland link previews—set dimensions near 1200×630 for best results.

Common use cases

  • Testing social share cards before campaigns
  • Generating og:title, og:description, og:image tags
  • Debugging wrong images on link previews
  • Validating Twitter card large image layout

How to use

  1. Fill in title, description, image URL, and canonical page URL.
  2. Pick card type (summary, summary_large_image, etc.).
  3. Preview how the card renders on major platforms.
  4. Copy meta tags into your page <head>.

Understanding the result

  • og:url should be the canonical share URL to consolidate engagement signals.
  • Image must be publicly HTTPS-accessible for platforms to fetch it.
  • twitter:card complements og: tags; some apps prefer Twitter-specific tags.
  • Cache busting: platforms cache previews—use their debugger tools to refresh after changes.

FAQ

Recommended og:image size?

1200×630 px is widely recommended for large image cards.

Why is the wrong image showing?

Platforms cache aggressively. Clear cache via Facebook Sharing Debugger or similar.

Open Graph vs Twitter Cards?

OG is Facebook's spec adopted widely. Twitter tags override or complement for X.

Relative image URLs?

Use absolute HTTPS URLs. Crawlers cannot resolve relative paths without base URL.
