Free Open Graph Generator
Build the og: tags that control how your links look on Facebook, LinkedIn, Slack, Discord and WhatsApp — with a live preview of the card before you ship.
Why use the Open Graph Generator
Private by design
No account needed. What you type stays in your browser unless you ask for an AI suggestion or name a URL to fetch.
See it before you ship
Live Google, Facebook and X previews show what your link will look like.
Export for your stack
Copy escaped HTML, or the equivalent for Next.js, Astro or Nuxt.
Frequently asked questions
What size should an og:image be?
1200×630 pixels, at a 1.91:1 ratio. Keep it under about 5 MB and use an absolute https URL — relative paths are ignored by every major crawler.
Why is my preview showing the old image?
Platforms cache aggressively. Use Facebook's Sharing Debugger or LinkedIn's Post Inspector to force a re-scrape after changing og:image.
Do I need Twitter Card tags if I have Open Graph?
Not strictly — X falls back to og: tags when twitter: ones are absent. Adding twitter:card explicitly is still worth it, since it is what selects the large-image layout.
