OGP (the Open Graph Protocol) is a set of meta tags that control how a page appears when shared on social media — its title, description, and preview image. They are defined with tags such as og:title, og:description, og:image, and og:url.

What is a Twitter Card?

A Twitter Card is X (Twitter)'s extension of OGP, set with tags like . You can choose a card type such as summary or summary_large_image; without it, X may not render a rich card.

Why isn't my OGP image showing on social media?

Common causes are a missing og:image, an image URL that is relative or still uses http, an image that is too small, or a stale cache on the social platform. Use this tool to confirm the tags that are actually fetched and check that og:image is set to an absolute URL.

What is the recommended OGP image size?

1200×630px (a 1.91:1 ratio) is widely recommended for large summary cards. At minimum, use 600×315px so the image renders crisply on the major social platforms.

Is the URL I enter sent to a server?

Yes. This tool fetches the URL you enter through our server and parses the OGP tags from the returned HTML. Only the URL you enter is fetched; nothing else is stored.

Yes, it is completely free. No sign-up and no installation required.
