Frequently asked questions
1200 × 630 pixels. That’s a 1.91:1 ratio, and it’s the shape X, LinkedIn, Facebook, Slack and Discord all crop to. Use PNG or JPG, keep it under 1 MB and keep text away from the edges.
X picks the card layout from the twitter:card tag. Without it, or set to summary, you get a small square thumbnail. Set it to summary_large_image for the full-width image.
og:title, og:description, og:image and og:url cover every platform. Add twitter:card for X, og:site_name for Slack and Discord, and og:image:width and og:image:height so the image shows on the first share.
Platforms cache previews, often for days. LinkedIn’s Post Inspector and Facebook’s Sharing Debugger fetch a fresh copy on demand. For Slack, Discord and iMessage, add a query string like ?v=2 to the link. This tool fetches your page fresh, so it shows the change within a minute.
Yes. Edit the title, description, image link or site name next to the preview and every card updates as you type. When it looks right, copy the finished tags into your page.
No. The tool fetches your page from our server, the same way X or Slack would. So it only sees public pages — localhost, private networks and logged-in pages are out of reach.
Yes. No account, no limits on what you check — just up to 10 checks a minute.
