Instantly check how your links appear on Twitter, Facebook, LinkedIn, and Slack.
Find broken images, missing tags, and low-quality previews — then fix them in 10 seconds with AI.
If your og:image is missing or broken, your link shows as a plain text card. On Twitter, 90% of users scroll right past it.
Before you share, check how your link actually looks on Twitter, Facebook, LinkedIn, and Slack — exactly as your audience will see it.
Our tool analyzes your OG tags and gives you a score out of 100. Low score? We'll show you exactly what's wrong and how to fix it.
If your preview looks bad, AutoOG AI can generate a perfect replacement image instantly — no design skills needed, no signup required.
An Open Graph (OG) image checker is a free tool that validates how your webpage will appear when shared on social media platforms like Twitter, Facebook, LinkedIn, and messaging apps like Slack or Discord. When you paste a URL into these platforms, they read the <meta property="og:image"> tag from your HTML to display a preview card. If this tag is missing, broken, or points to a low-quality image, your link will have poor engagement.
Studies show that links with high-quality OG images get 3–5× higher click-through rates on social media compared to text-only links. If you're sharing blog posts, product launches, or landing pages, a broken OG image is leaving traffic on the table.
