When someone shares your link, social networks read its Open Graph tags to build the preview card: the title, description and image. Without them, platforms guess — often badly. Fill in the fields and see a live Facebook/LinkedIn-style preview as you type.

The generator checks your og:image size against the recommended 1200 × 630 px, supports the article, product and profile types, and can import the current tags from any URL so you can fix an existing page quickly.

Tips and good to know

What size should an Open Graph image be?

1200 × 630 pixels (a 1.91:1 ratio) displays well on Facebook, LinkedIn and most other platforms.

Why doesn't Facebook show my new image?

Facebook caches previews. Paste the URL into Meta's Sharing Debugger and click “Scrape Again”.
