OG Share Image Checker
Verify that your Open Graph and Twitter Card images are properly defined and reachable. Ensure your links stand out with high-quality previews when shared on social media.
How to use the Check OG Share Image
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.

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.
