Open Graph Preview
See exactly how your link will look when shared on social media.
What a social platform sees when you share a link
When you paste a URL into Facebook, LinkedIn, X or WhatsApp, the platform does not read your page the way a visitor does. It looks for a specific set of meta tags in the HTML head — the Open Graph tags — and builds a preview card from whatever it finds. Supply nothing and the platform improvises, usually by grabbing the first image on the page and a fragment of text that was never meant to be a headline.
Four tags do most of the work. og:title is the headline of the card, og:description the supporting line beneath it, og:image the picture, and og:url the canonical address. X reads its own twitter: equivalents but falls back to Open Graph when they are absent, which is why the tag block above includes both.
Sizing, truncation and stale previews
Use a 1200 by 630 pixel image: it is the size every major platform crops cleanly from. Keep titles near 60 characters and descriptions near 155, because anything longer is trimmed with an ellipsis in the exact place you were making your point. And if you update your tags and the old card keeps appearing, that is caching rather than a mistake — each platform holds its own copy of the preview and needs to re-scrape the URL before the new version shows.
Frequently asked questions
What are Open Graph tags?
Open Graph tags are meta tags in a page's HTML that tell social platforms which title, description and image to display when the page is shared. Without them, platforms guess, and the result is often wrong.
What image size should I use for social sharing?
A 1200x630 pixel image is the widely used standard. It displays well on Facebook, LinkedIn and X, and it degrades gracefully to smaller cards.
Why does my link still show an old image after I updated it?
Social platforms cache the preview. After changing your tags you usually need to re-scrape the URL in the platform's own debugging tool to force a refresh.
Does this tool fetch my page?
This preview builds the card from the values you enter, so you can design and check a card before publishing. To see live tags, paste your current title, description and image URL.
