Social Media Link Preview Checker
Check how your link will look before you share it on launch day. Enter any page address and this tool reads its Open Graph and Twitter Card tags, then draws the preview card that X, LinkedIn, Facebook and Slack build from them: the image, the title, the description and the domain. Underneath, it lists exactly what is missing or wrong, such as a missing og:image, a relative image path, an empty description or no twitter:card, so you can fix it before anyone sees a blank grey box. It reads the page the way the social networks do, from the HTML your server sends.
How to use Social Media Link Preview Checker
- Paste the address of the page you are about to share.
- Press Check preview to see the cards for X, LinkedIn, Facebook and Slack.
- Fix anything flagged in the list, publish, and check again.
Frequently asked questions
Why does my link show no image when I share it?
Usually the page has no og:image tag, the image path is relative instead of a full https address, or the image is too small or blocked. This checker shows which one it is.
What size should an Open Graph image be?
1200 by 630 pixels is the common choice: it fills the large card on X, LinkedIn and Facebook without being cropped awkwardly.
I fixed my tags but X or LinkedIn still shows the old preview. Why?
The networks cache previews. LinkedIn has a Post Inspector that refreshes it; on other networks the cache clears on its own after a while.
