What is an OG Image Checker?
An OG Image Checker (Open Graph Image Checker) is a free tool that previews how your web page appears when shared on social media platforms like Facebook, LinkedIn, X (Twitter), Slack, and WhatsApp. It validates your Open Graph meta tags, Twitter Card tags, and displays the exact title, description, and preview image that will appear.
Open Graph tags are HTML meta tags created by Facebook (Meta) that control how URLs are displayed when shared on social media. Without proper OG tags, your links may show broken images, incorrect titles, or missing descriptions—hurting click-through rates and engagement.

Frequently Asked Questions
How do I fix missing OG images?▾
Add <meta property="og:image" content="URL"> to your page's <head> section. Use a 1200x630px image hosted on a public URL.
Why is my old image still showing?▾
Social platforms cache meta tags for 24-48 hours. Clear Facebook cache at Facebook Debugger and LinkedIn at LinkedIn Post Inspector.
What's the best OG image size?▾
1200x630px (1.91:1 ratio) works best across all platforms. Keep file size under 5MB and use JPG or PNG format.
Do I need different tags for Twitter?▾
X (Twitter) uses Twitter Card tags (twitter:image) but falls back to Open Graph tags if Twitter Card tags aren't present. OG tags usually work fine. Learn more in our X scheduling guide.

The four required OG tags are: og:title, og:type, og:image, and og:url. Optional but recommended: og:description, og:site_name. See the official Open Graph protocol for full specs.

Check meta tags whenever you: publish new content, update page titles/descriptions, change featured images, or redesign your site. Also check before running major social media campaigns to ensure perfect previews.
