Social card preview

See the exact card people see when your link is shared — on X, Facebook/Telegram and LinkedIn. Paste a URL; we read its Open Graph tags and render each platform's card with warnings.

What this tool checks

A social share preview shows how a link will render as a card on X, Facebook, Telegram and LinkedIn, built from the page's Open Graph (og:) and Twitter Card meta tags. When those tags are missing, truncated, or point to a broken image, platforms fall back to a bare URL or the wrong text — hurting click-through and leaving social bots and AI crawlers without a clean title, description or image to represent your page.

What it looks at

og:title: The headline platforms print on the card; when absent they scrape the <title> or show a bare URL, and an over-long og:title gets truncated into a weak card.
og:description: The one-line summary under the title; kept near 110-160 characters it survives truncation, while its absence leaves the card blank or auto-filled with stray body text.
og:image: The preview thumbnail; it must be an absolute HTTPS URL to a reachable file (ideally 1200×630, under ~5 MB) or the card renders imageless or broken.
twitter:card: Tells X whether to draw a small square (summary) or a large banner (summary_large_image); without it X falls back and your image may not show at full size.
og:url / canonical: The canonical link the card points to; a wrong or relative og:url sends shares and the platform's cache to the wrong or non-existent address.
og:type / og:site_name: Type (website, article) and site name give platforms context and a brand label above the title; omitting them makes the card look generic and unbranded.

How to use it

Paste your page URL and run the preview to render the X, Facebook/Telegram and LinkedIn cards side by side.
Review the flagged warnings — missing og:image, truncated title, a non-absolute image URL, or an absent twitter:card.
Fix the offending meta tags in the page <head>, redeploy, and re-check — then clear the platform cache (e.g. Facebook's Sharing Debugger) so the new card is scraped.

Frequently asked questions

Why does my link show no image when shared?

Usually the page has no og:image, or og:image points to a relative path or a URL the platform can't reach. Set og:image to an absolute HTTPS URL of a live image (1200×630 works everywhere) and re-scrape.

What's the ideal Open Graph image size?

1200×630 pixels (a 1.91:1 ratio) is the safe size — it fills the large card on X, Facebook, Telegram and LinkedIn without cropping. Keep the file under ~5 MB and serve it over HTTPS.

Do X, Facebook and LinkedIn read the same tags?

They share the core Open Graph tags (og:title, og:description, og:image), but X also reads twitter:card and twitter:* tags and prefers them when present. This tool renders all three cards so you catch platform-specific gaps in one pass.

Why does the old preview still show after I fixed the tags?

Platforms cache the scraped card. Force a refresh in each platform's debugger — Facebook's Sharing Debugger, LinkedIn's Post Inspector, or by re-sharing on X — so they re-fetch the updated Open Graph tags.
