Link preview tester
See the title, description and image a link shows when you share it.
How it works
We load the page the way a link unfurler does and read its <title>, Open Graph (og:) and X card (twitter:) tags. The previews are close approximations; each app crops and caches a little differently.
Still seeing an old preview?
X, Slack and Discord cache previews for hours or days. After you fix your tags, share the link with a harmless query string like ?v=2 to see the new card.
Privacy
Only public pages can be tested, and nothing is stored. Images in the previews load straight from the site.
