OG Card Preview

About

OG Card Preview is a free Chrome extension built for web agencies, developers, and SEO professionals who need to quickly inspect and validate Open Graph and social card tags without leaving the browser.

🔍 INSTANT SOCIAL PREVIEWS
See exactly how your page will appear when shared on Twitter/X, LinkedIn, and Facebook — including the card image, title, description, and site name — all rendered in realistic card previews.

✅ FULL TAG AUDIT
Get a scored audit of all required and optional OG and Twitter meta tags with pass/fail indicators. Checks og:title, og:description, og:image, og:url, og:type, twitter:card, meta description, canonical URL, and more.

📐 IMAGE DIMENSION CHECK
Automatically checks your og:image dimensions and flags images that are too small or the wrong aspect ratio for social sharing.

📋 ONE-CLICK COPY
Copy any tag value instantly from the audit panel.

📤 EXPORT REPORTS
Export your full audit as JSON (for developers) or Markdown (for client reports and documentation).

📸 SNAPSHOT COMPARE
Save a snapshot of your OG tags at any point and compare against the current state. Supports full history (up to 10 snapshots per domain) with per-snapshot notes, prev/next navigation, and tag-level diff showing what was added, removed, or changed.

🔗 VALIDATOR SHORTCUTS
Quick links to the Twitter/X Card Validator, LinkedIn Post Inspector, and Facebook Sharing Debugger — plus Nahnu Media's own free OG preview tool.

⚙️ FULLY CUSTOMIZABLE
Toggle any feature on or off from the Settings tab — show/hide the Facebook tab, Compare tab, validator links, copy buttons, image dimension checks, export buttons, snapshot notes, and the missing-tag badge.

🔴 MISSING TAG BADGE
Optionally shows a red badge on the extension icon with the count of missing required tags, so you can spot issues at a glance without opening the popup.

☀️ LIGHT & DARK PREVIEW MODES
Switch between dark and light card rendering to see how your links will appear across different browser themes.
