OG Image Checker
Check your Open Graph image before you share
Paste a URL to see the og:image it declares and how that image appears in link previews. Catch missing, cropped, blurry or broken social images before your link goes out.
Image found
Check that the page has an og:image tag with an absolute HTTPS URL. Without it, platforms pick a random image from the page or show no image at all.

Size and ratio
Use 1200 x 630 pixels, a 1.91:1 ratio. Smaller images may be shown as a small thumbnail, and other ratios get cropped differently on each platform.

File and format
Use JPG or PNG under 5 MB. Keep important text and logos away from the edges, since some apps crop the image to a square or a narrower card.
Platform previews
Compare how the same image looks on LinkedIn, X, Slack, WhatsApp and Google so the preview is clear and on-brand everywhere.

A practical guide to OG images
The OG image is usually the largest part of a link preview, so it has a big effect on whether people click. Here is how to check and improve it.
What is an OG image?
An OG image is the picture set with the og:image meta tag from the Open Graph protocol. Social networks and messaging apps read it to build the preview card when someone shares your link.
What is the best OG image size?
1200 x 630 pixels works on almost every platform. It matches the 1.91:1 large card on LinkedIn, Facebook and X. Add og:image:width and og:image:height tags so platforms can render the image faster.
How to check an OG image
Enter the page URL and run the check. Confirm the image loads, has the right ratio, and reads well at small sizes. Then look at each platform preview for cropping or text that is too small.
Why is my OG image not showing?
Common causes are a relative image URL, an image blocked by robots.txt or a login, a file that is too large, a wrong content type, or a cached old preview. Fix the tag, republish, and refresh the cache in the platform's debugger.
OG image vs. Twitter card image
X reads twitter:image first and falls back to og:image. Set twitter:card to summary_large_image to get the large image layout. In most cases one 1200 x 630 image can serve both.
Tips for OG images that get clicks
Use a clear headline or product shot, high contrast, and a recognizable logo. Keep text short and large, and create a unique image for important pages instead of reusing one site-wide image.
