Why does my link preview look wrong or blank?

Usually a missing or mis-sized og:image, a missing og:title/description, or the image being too small. This tool reads the page's actual tags and shows what each platform will render, so you can spot the gap.

What's the right Open Graph image size?

1200×630 px (1.91:1) is the universal standard for large summary cards on X, Facebook and LinkedIn. The generator here outputs exactly that.

Do social platforms cache the preview?

Yes — after you fix your tags, use each platform's debugger (Facebook Sharing Debugger, LinkedIn Post Inspector) to refresh their cache, or they'll keep showing the old preview.

Social card FAQ

Which meta tags matter most?

og:title, og:description, og:image (1200×630) and twitter:card=summary_large_image. With those four right, every major platform shows a great card.

Why can't it fetch some sites?

Pages behind a login, aggressive bot protection, or strict CORS can't be read. For those, paste your tags manually or generate the image and preview with your own values.

Where do I put the generated image?

Host it on your site and reference it in <meta property="og:image" content="…">. Need the tags written for you? Use our meta tag generator.
