Link preview checker

See the card X, LinkedIn, Facebook, WhatsApp, Slack and iMessage build when someone shares your page, and what to fix before you post it.

Free, no account. We read the page once and keep nothing.

Your cards appear here

Paste the page you are about to share, then check it. Or see a finished reading first.

og:title
The headline of the card. Without it, most networks fall back to the page title.
og:description
The line under the headline on Facebook, WhatsApp and Slack. Large cards on X and LinkedIn show none.
og:image
The picture, as a full https:// address. It makes the card large on most networks.
og:image:alt
What the image shows, read aloud by screen readers.
og:url
The address Facebook files the card under, so shares of one page count together.
twitter:card
The X card type: summary_large_image gives the full-width card. X reads the og: tags when its own are missing.
  1. 1200 × 630 pixels. Facebook's recommended size, a hair from LinkedIn's 1200 × 627, and cropped only slightly by X's 2:1 frame.
  2. Under 600 KB. WhatsApp's limit for a link image, far below the 5 MB that X and LinkedIn accept.
  3. A JPG or a PNG. X also takes WEBP and GIF, and documents that it does not support SVG.

Why does my card still show the old image?

Networks keep a copy of a card from the first time a link is shared. Facebook’s Sharing Debugger and LinkedIn’s Post Inspector fetch it again on request, and adding a query string such as ?v=2 makes any network treat the link as new.

Is this exactly what each app shows?

The tags, the image checks and the limits come from what each network publishes. The cards are drawings of each layout, and the apps restyle them from time to time, so an app’s own composer has the final word.

Do you keep the pages I check?

No. Our server fetches the page and its image once to read them, sends you the result, and stores neither the address nor the result.

Why does it say my site’s bot protection answered?

Firewalls such as Cloudflare’s turn away automated visitors they do not recognise, and this check is one. The networks’ crawlers are often let through as verified bots, so your cards may still work.
