Free tool · Link preview tester

How does your link look when it’s shared?

Enter a page and see its preview on X, LinkedIn, Facebook, WhatsApp, Slack and Discord, with the share image checked and a short list of what to fix.

Checks the page the way link-preview crawlers fetch it.

How this works
  • The check reads the tags apps use for previews (Open Graph and X card tags), fetching the page the way their crawlers do.
  • The share image is downloaded to check that it loads and to measure its size and weight.
  • Previews are close approximations; each app styles them its own way.
  • Apps keep a copy of a preview for days. After a fix, refresh old shares with each platform’s own tool, such as Facebook’s Sharing Debugger or LinkedIn’s Post Inspector.
