What is Open Graph Preview Tool?

Open Graph (OG) tags are HTML meta tags that control how a web page appears when shared on social media. When you share a URL on Facebook, LinkedIn, Slack, or WhatsApp, those platforms fetch OG tags to display a rich preview card with title, description, and image. Without OG tags, the platform generates a generic fallback. With well-crafted OG tags, a shared link becomes a click-worthy card that drives significantly more engagement.

The four essential OG tags are `og:title`, `og:description`, `og:image` (ideally 1200×630px), and `og:url`. This tool fetches OG tags from any URL and renders a visual preview of how the link card will appear on Facebook, LinkedIn, and Twitter simultaneously. It catches common issues: wrong image dimensions, truncated titles, missing descriptions, or image URLs that return 403 errors when fetched by a bot.

Open Graph Preview Tool FAQs

Quick answers about the workflow, privacy, and where this tool fits in a broader job.

What image size does Open Graph require?

Recommended: 1200×630px at 1.91:1 aspect ratio. Minimum: 600×315. Images smaller than 200×200 are not used as previews. Always use an absolute https:// URL for og:image.

Why does my link look different on Facebook vs LinkedIn?

Each platform has different card dimensions, character limits, and fallback behavior. Facebook trims og:description at ~200 characters; LinkedIn allows more. Check previews on each platform separately.

My OG tags are correct but the preview looks wrong. Why?

Social platforms cache previews aggressively. Use the Facebook Sharing Debugger or LinkedIn Post Inspector to force a cache clear. Changes may take minutes to hours to appear.
