Social Card Preview
See how your link looks on Facebook, X, LinkedIn, Slack and WhatsApp — before you share it and find out the hard way.
1. Paste your page tags
Copy the <head> section of your page — or just its <meta> tags — and paste it here. The tags are parsed in your browser; nothing is sent anywhere. This works for pages that are not live yet: URL-based checkers need a server to fetch the page, so they cannot preview localhost, staging or login-walled pages. This one can.
2. Or fill in the card yourself

Frequently asked questions
Why does my link show the wrong image when I share it?
Usually one of three things: the page has no og:image (or has two, and the wrong one comes first), the image URL is relative or http instead of absolute https, or the platform is showing an old copy from its cache. The audit above checks the first two; for the cache, re-scrape the link in the Facebook Sharing Debugger or LinkedIn Post Inspector.
Can I preview a page that is not live yet?
Yes. URL-based checkers need a server to fetch your page, so they cannot see localhost, staging or login-walled pages. This tool reads the tags you paste, so it works before the page is ever deployed.
What image size should I use?
One 1200×630 JPG under 5 MB works on Facebook, LinkedIn and X. Keep important text and faces in the middle: X uses a slightly wider crop, and some apps trim the top and bottom.
Why does X show a small card instead of the big image?
X renders the large card only when twitter:card is set to summary_large_image. Without it, X falls back to the small summary layout even if your og:image is perfect.
Is anything I paste uploaded?
No. Your tags are parsed entirely inside your browser, and the preview image is only loaded by your own browser to be displayed. Nothing is sent to any server.
What does the free version include?
Unlimited previews on all five platforms, the full tag audit, and corrected meta tags to copy. Social Card Preview Pro ($29 one-time) adds saved card presets in your browser and removes ads.
