About this tool

Open Graph and Twitter Card meta tags control the title, description and image shown when your page is shared on social platforms and chat apps. Fill in your details and this tool renders a live preview of the share card and generates the exact meta tags to paste into your <head>.

For the sharpest cards, use an image around 1200×630px. Everything is previewed locally in your browser.

Frequently asked questions

What image size should I use?

1200×630px (a 1.91:1 ratio) is the recommended Open Graph image size and renders well across platforms with the large summary card.

Why isn't my image showing when I share?

Common causes are a non-absolute image URL, an image that's too small, or the platform caching an old version. Use each platform's debugger to re-scrape after updating.

Do I need both Open Graph and Twitter tags?

Open Graph covers most platforms (Facebook, LinkedIn, WhatsApp, Slack). Adding twitter:card tags gives you precise control on X. This tool generates both.

Is my data uploaded?

No. The preview and tag generation happen entirely in your browser.
