How link previews work
When you paste a link into X, Facebook, LinkedIn, or iMessage, the platform fetches your page and reads special meta tags in the <head>:
og:title— the headline on the cardog:description— the 1–2 sentence teaserog:image— the preview image (absolute URL, ideally 1200×630)og:url— the canonical page addresstwitter:card— set tosummary_large_imagefor big X cards
No tags? The platform guesses — usually badly. A missing og:image is the #1 reason shared links look broken.
🖼️ Image rules that matter
Use 1200×630px, absolute https:// URL, under 1 MB, JPG or PNG. Facebook crops to 1.91:1; X large cards show ~2:1. Keep key text away from the edges.
Frequently asked questions
What is an Open Graph social card?
When you share a link on X, Facebook, LinkedIn or iMessage, the platform reads your page's Open Graph (og:) and Twitter Card meta tags to build a preview card with an image, title and description. This tool shows you exactly what that card will look like before you publish.
Why doesn't my link show an image when shared?
The most common causes: missing og:image tag, an image smaller than 200×200px (use 1200×630 for best results), a relative image URL instead of absolute, or the platform cached an old version — use each network's debugger to refresh the cache.
Can this tool fetch meta tags from my URL automatically?
It tries, using a public CORS proxy. Many sites block automated fetching, so if auto-fill fails, just paste your title, description and image URL manually — the preview updates live either way.
What image size works best for social cards?
1200×630 pixels is the universal safe choice — it looks sharp on Facebook, LinkedIn and X large cards. Keep the file under 1 MB and use an absolute https:// URL.
Is my URL sent to a server?
No. Everything renders locally in your browser. The optional auto-fill uses a public proxy to read the page's meta tags, but nothing you type is stored anywhere.
