What is Open Graph and why does it matter for sharing?

Open Graph is a protocol developed by Facebook that uses HTML meta tags (og:title, og:description, og:image) to control how a URL looks when shared on social media or messaging apps. Without proper OG tags, platforms either show a plain link or auto-guess content, often producing ugly or misleading previews.

Why does my link show no preview or a blank image on social media?

Common causes: missing og:image tag, image URL returning a 404 error, image too small (minimum 200×200 px recommended), the page is behind a login wall, or social platform caches an old version. Use this checker to diagnose the exact missing or broken tag, then fix it and request a cache refresh through the platform's sharing debugger.

What is the difference between Open Graph tags and Twitter Card tags?

Open Graph tags (og:*) are the standard used by Facebook, LinkedIn, Slack, Discord, and most platforms. Twitter/X uses its own twitter:card tags (twitter:title, twitter:image, twitter:card) and falls back to OG tags if Twitter-specific ones are absent. Best practice is to set both sets of tags — this checker shows you all of them.

How do I fix a missing or wrong OG image?

Add or update the tag in your page's . Use an absolute URL (not relative), aim for 1200×630 px at minimum, keep the file under 8 MB, and use JPG or PNG. After updating, use this checker to verify the tag is correct, then clear the platform's cache using Facebook's Sharing Debugger or LinkedIn's Post Inspector.

About

When you share a URL on social media or messaging apps, platforms read Open Graph (OG) meta tags from the page's HTML to build a rich preview card — showing a title, description, and thumbnail image. If these tags are missing or misconfigured, shares can look plain, use wrong images, or show the wrong title. This tool sends the URL to our server, which fetches the page HTML and parses all OG and standard meta tags (og:title, og:description, og:image, og:type, twitter:card, twitter:image, and more), then returns the parsed values so you can see exactly what social platforms will display. No files are uploaded — just supply a public URL and click Check.
