Social Share Preview (Open Graph Checker)
Paste any page URL into this free OG preview tool and see exactly how it will unfurl when shared on Facebook, X (Twitter) and LINE. It reads the page's Open Graph and Twitter Card tags, rebuilds the share card the way each platform does, and flags missing or weak tags — so you can fix your link preview before it goes live, not after. Built for marketers, social media managers and content teams.
Your share cards will appear here
Enter a URL and click Preview to see how it unfurls on social media.
The preview shows the real og:image, fetched securely through our server so it displays even when the site blocks hotlinking. If an image can't be loaded, the resolved image URL and dimensions are shown instead.

Frequently asked questions
Is the OG preview tool free?
Yes — it is completely free with no sign-up. Just paste a public page URL and it fetches the page and builds the share cards for you.
Does it show the real preview image?
Yes. The tool fetches the real og:image securely through our server, so the card shows the actual picture even when the site blocks hotlinking. If an image can't be loaded, the resolved image URL and its dimensions are shown instead.
What is an Open Graph (OG) tag?
Open Graph tags are meta tags in your page's HTML head — like og:title, og:description and og:image — that tell Facebook, LINE and other platforms exactly what to show when your link is shared. Without them, platforms guess, and the card usually looks worse.
How is the X (Twitter) card different from the Facebook card?
X uses its own twitter:card tags, but falls back to your Open Graph tags when they are missing. The twitter:card value decides the layout: "summary_large_image" shows a big banner image, while "summary" shows a small square thumbnail. We render whichever your page declares.
Does this tool work with Thai pages?
Yes. It correctly handles Thai text, including legacy TIS-620 and Windows-874 encoded pages, converting them to UTF-8 so your Thai titles and descriptions preview accurately.
