## Overview

Paste a URL to preview how the link looks on X, LinkedIn, and Facebook. Free OG image checker for missing tags, image size, and broken previews. No signup.

Paste a public http or https URL. The checker reads og:title, og:description, og:image, og:url, twitter:card, twitter:image, the document title, and the meta description, then shows how the link card looks on X, LinkedIn, and Facebook.

## FAQ

### What is an OG image?

An OG image is the picture shown when your link is shared. It is set with the og:image meta tag. X, LinkedIn, and Facebook pair it with og:title and og:description to build the preview card.

### What is the best OG image size?

Use 1200×630 pixels. That is Facebook's recommended size, and the same 1.91:1 image works on X and LinkedIn (LinkedIn also accepts 1200×627). Export a JPG, PNG, or WebP and put an absolute https URL in og:image.

### Why isn't my social preview updating?

X, LinkedIn, and Facebook cache link cards. This checker reads the live page, so it can show a new image before those networks do. After you deploy the fix, refresh the cache with X's Card Validator, Facebook's Sharing Debugger, or LinkedIn's Post Inspector, then share the link again.

### Does this checker store my URL?

No. The page is fetched to read its tags, the result stays in your browser, and the URL is not saved.
