Open Graph Checker extracts social sharing tags from pasted HTML and renders a local preview card. It helps verify titles, descriptions, images, URLs, and Twitter card basics before publishing.
Social preview
No. Paste HTML from your page source or build output. The tool does not request external URLs, so it can preview pages that aren't publicly live yet.
Each platform (Facebook, LinkedIn, X, Discord) caches, crops, and renders preview cards slightly differently and on its own schedule. This tool checks the underlying tags and gives a local, best-effort approximation, not a pixel-perfect match to any one platform.
Common causes: a relative image path instead of an absolute URL (Open Graph requires absolute URLs), a missing og:image tag entirely, or an image the platform's crawler can't reach — this tool flags the tag's presence and value but can't verify the image loads on every platform.
Social platforms cache Open Graph data aggressively and don't always re-fetch on every share. This tool shows what your current HTML declares, not what a platform has cached from a previous crawl — you may need each platform's own cache-refresh/debug tool to force an update there.
At minimum: og:title, og:description, og:image, and og:url. Missing any of these typically causes a platform to fall back to generic page metadata or an unpredictable default preview.
Yes — it extracts twitter:card, twitter:title, twitter:description, and twitter:image alongside the Open Graph fields, since platforms like X primarily use the twitter: namespace when present.
