OG Card Preview

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.
