Open Graph Preview
See how your page looks when shared on Facebook, LinkedIn, and X — and catch missing og:title, og:image, or Twitter Card tags before you publish.
Frequently asked questions
What is an Open Graph preview?+
It shows how a page will look when shared on Facebook, LinkedIn, and X (Twitter), based on the page's Open Graph (og:) and Twitter Card meta tags. It catches missing or wrong tags before you publish or share.
What image size should og:image be?+
Use 1200×630 pixels (a 1.91:1 ratio) for the large-image card. Keep it under ~5 MB and use an absolute HTTPS URL. Twitter's summary_large_image uses the same asset.
Why does my link show no image when shared?+
Usually a missing or relative og:image, an image behind auth, or a platform cache. Add an absolute og:image URL, set twitter:card to summary_large_image, and re-scrape with the platform's sharing debugger.
Can I preview a live URL?+
Yes. Enter a URL and the tool fetches the page and reads its meta tags, or paste your HTML directly. It is free, needs no signup, and runs in your browser.
