Frequently asked questions

What is an Open Graph image?

An Open Graph image (og:image) is the preview picture that appears when your link is shared on Facebook, LinkedIn, iMessage, Slack, and other platforms. It's set with a <meta property="og:image"> tag in your page's <head>.

The complete guide to Open Graph images

What size should an Open Graph image be?

The recommended Open Graph image size is 1200 × 630 pixels (a 1.91:1 ratio), under 8 MB, in PNG or JPG. Images that are too small, the wrong ratio, or missing width and height tags get cropped or dropped by some platforms.

OG image sizes, specs, and the one mistake that breaks previews

Why isn't my link preview showing an image?

Common causes: the og:image URL is relative instead of absolute, served over http instead of https, blocked to crawlers, returns a 404, or the tag is missing entirely. Paste your URL above to see which applies.

Why your links look broken without OG images

What is JSON-LD structured data?

JSON-LD is a script in your page's <head> that describes the page to search engines and AI — product, article, breadcrumb, and organization data in a machine-readable form. It powers rich results and increasingly feeds AI answers.

Structured data for AI and SEO

Does Google use Open Graph tags?

Google doesn't use Open Graph tags for ranking, but it may fall back to them for preview snippets, and social platforms rely on them entirely. For search, pair them with JSON-LD structured data — this tool checks both.
