Question 1

What is the OG Image Debugger?

Accepted Answer

The OG Image Debugger fetches any URL and shows exactly how its Open Graph (og:title, og:description, og:image, og:url) and Twitter Card meta tags will render when shared on Facebook, Twitter, LinkedIn and Slack. It also flags missing or malformed tags.

Question 2

How does it fetch external pages?

Accepted Answer

The tool uses the public allorigins.win CORS proxy to fetch HTML from any public URL, then parses the <meta> tags in your browser. No data is stored — everything is client-side after the fetch.

Question 3

What does it check?

Accepted Answer

It checks for og:title, og:description, og:image, og:url, og:type, og:site_name, twitter:card, twitter:title, twitter:description, twitter:image, image size (recommended 1200x630), and warns about missing fields or undersized images.

Question 4

Can I paste HTML source instead of fetching a URL?

Accepted Answer

Yes. Switch to the 'Paste HTML' tab and paste raw HTML — the tool parses the meta tags without making any network request. Useful when testing pages that are not publicly accessible.
