Open Graph Checker
Preview Open Graph title, description and image as they may appear on social platforms.
What this tool checks
This tool extracts og:title, og:description, og:image and og:url from any page and renders a preview card showing how the page would appear when shared on social platforms like Facebook, LinkedIn or Slack.
Why it matters
Without Open Graph tags, social platforms generate their own preview using whatever content they can find — often resulting in a missing image, wrong title or generic description. Proper OG tags control your brand presentation everywhere.
How to fix common issues
Add og:title, og:description and og:image to every important page. Use images at least 1200×630 pixels. Keep og:title under 60 characters and og:description under 155 characters. Test with this tool after changes.
Frequently asked questions

- What image size should I use for og:image?
- Facebook recommends 1200×630 pixels. This size works well across most social platforms and messaging apps.
- Does this tool check Twitter Card tags?
- This tool focuses on Open Graph tags (og:title, og:description, og:image, og:url). Twitter falls back to OG tags when Twitter-specific tags are not present.
