About OG Image Preview

Enter any URL to instantly preview your link's appearance on every major social platform — Facebook, X (Twitter), LinkedIn, Discord and Slack — using the actual Open Graph and Twitter Card metadata fetched from the live page. Each platform card is rendered pixel-accurately with the real title, description, image and domain. Missing OG tags, missing Twitter Cards, images with wrong dimensions, low-resolution images and unsafe HTTP image URLs are all detected and flagged. An overall Social Sharing Score (0–100) surfaces every issue with specific, actionable recommendations. Export the full audit as JSON, TXT or a print-ready PDF.

Frequently Asked Questions

An OG (Open Graph) Image Preview shows you exactly how your webpage will look when someone shares its URL on social media. Facebook, LinkedIn, Discord and Slack use the og:title, og:description and og:image meta tags to build the link preview card. Twitter/X uses twitter:card, twitter:title, twitter:description and twitter:image — or falls back to Open Graph tags.

The recommended size is 1200×630 pixels (1.91:1 aspect ratio). This renders sharply on all platforms. The minimum for a large image card is 600×315. Images smaller than 200×200 are displayed as thumbnails rather than large hero cards. Keep the file size under 8 MB.

Twitter supports four card types: summary (small square thumbnail + text), summary_large_image (full-width image above text), app (for mobile apps) and player (for video/audio). The summary_large_image type gives the most visual impact and is recommended for blog posts, articles and landing pages.

Facebook caches OG data aggressively. After updating your tags, use the Facebook Sharing Debugger to force a cache refresh. Also check that your og:image URL is absolute (starts with https://), the image is publicly accessible without login or referrer restrictions, and the image is at least 200×200 pixels.
