Social card preview

See how your link looks on X, Facebook and LinkedIn before you share it, right in your browser.

Platform
Note: the preview is built in your browser; the only thing fetched is the image URL you enter, so you can see how it crops. Real platforms cache previews, so use their own debuggers for a final check. A 1200x630 image gives the cleanest result everywhere.
Social Card Preview is a free SEO tool that shows how a link will appear when shared on X, Facebook and LinkedIn, rendered in your browser from the title, description, URL and image you enter. It generates the matching Open Graph and Twitter card tags to copy, and the only thing fetched is the image you point it at, so nothing else is sent.

Frequently asked questions

Is my data uploaded anywhere?

No. The previews are drawn in your browser from what you type. The only thing fetched is the image at the URL you provide, so you can see how it will be cropped. Nothing else is sent.

Why might the real preview differ?

Social platforms cache previews and may apply slightly different cropping or fonts. This tool shows a close approximation; for a final check use each platform's own debugger to refresh the cache.

What image size works best?

A 1200 by 630 pixel image (1.91 to 1) looks right on X, Facebook, LinkedIn, Slack and Discord. Keep important text and faces near the centre so nothing important is cropped.

Do I need both Open Graph and Twitter tags?

Open Graph tags cover most platforms, and X uses them as a fallback. Adding twitter:card set to large image ensures X shows the big image rather than a small thumbnail, so the generated snippet includes it.

Can I copy the tags?

Yes. The matching Open Graph and Twitter tags are generated below the preview, ready to paste into your page's head.
