One check before every share.
Paste a URL. Previewcard fetches the page, reads the Open Graph and Twitter Card tags the way a social platform does, and renders exactly what a shared link will show.
What you get
Real card preview
See your link the way LinkedIn, Twitter, Facebook, and Slack will render it — title, description, image, and domain exactly as they appear.
Tag-by-tag diagnostics
Every Open Graph and Twitter Card tag is read individually. Missing tags are named. Image URLs are resolved, fetched, and measured for real dimensions.
Image resolution check
A relative og:image path is the single most common cause of a broken card. Previewcard resolves it, fetches it, and reports its real status and dimensions.
Platform-specific reporting
og: and twitter: are different vocabularies with different fallbacks. You see which platform sees what, not a merged guess.
How it works
Paste your URL
Paste any link you are about to share — a blog post, product page, press release, anything.
Previewcard fetches it
The tool fetches the page, parses the <meta> tags, resolves the image URL, and fetches the image itself to confirm it resolves and measure its dimensions.
See the result
A rendered social card shows exactly what the platform will display. Below it, a diagnostic section lists every tag, its value, and its status — missing, present, or broken.
