How to use the Open Graph Image Checker

When you paste a link into X, LinkedIn, Slack, or WhatsApp, those platforms read your page’s Open Graph tags to build the preview card. A missing or broken og:image means your links show up as plain, low-click text. This checker shows exactly what social platforms see before you share.

1Paste the URL you want to check.
2The tool fetches the page and reads its Open Graph and Twitter Card tags.
3See whether the preview image is declared, reachable, and correctly sized.
4Fix any missing tags and re-check to confirm your preview looks right.

Frequently asked questions

What is an Open Graph image?

The Open Graph image (og:image) is the preview picture that appears when your link is shared on platforms like Facebook, LinkedIn, X, Slack, and WhatsApp. A correct, high-quality image makes your links stand out and earn more clicks.

What size should an Open Graph image be?

The recommended size is 1200×630 pixels (a 1.91:1 ratio), which displays cleanly across most social platforms. Keep the file under about 5 MB and use PNG or JPG.

Why is my social preview image not showing?

Common causes are a missing og:image tag, a relative instead of absolute image URL, an image that is blocked or too large, or a cached old preview. This checker shows which tags are present and whether the image is reachable so you can pinpoint the issue.

Why does an old image still show after I changed og:image?

Platforms cache link previews. After updating the tag, re-scrape the URL with the platform’s own tool — Facebook Sharing Debugger or LinkedIn Post Inspector — or add a version query string to the image URL so it is treated as a new file.
