What is OG Meta Tag Preview?
OG Meta Tag Preview is a free online tool that shows you exactly how your web pages will appear when shared on social media platforms. Open Graph (OG) meta tags are HTML elements that control the title, description, image, and URL displayed in social media link previews on Facebook, Twitter/X, LinkedIn, and Google search results. Getting these tags right is essential for driving click-through rates from social shares. This tool provides real-time visual previews across four major platforms so you can perfect your meta tags before deploying them to production.
How to Use This Tool
Enter your Open Graph values in the input fields: og:title, og:description, og:image URL, og:url, and og:site_name. Select your preferred Twitter card type (summary or summary_large_image). Switch between the Facebook, Twitter/X, LinkedIn, and Google preview tabs to see how your page will appear on each platform. The tool generates the complete set of meta tags, including both Open Graph and Twitter Card markup, ready to copy and paste into your HTML head section.
Common Use Cases
- Testing and perfecting social media previews before publishing blog posts or landing pages
- Debugging why shared links display incorrect titles, descriptions, or images
- Generating complete Open Graph and Twitter Card meta tag markup for new pages
- Comparing how the same content appears across Facebook, Twitter, LinkedIn, and Google
Why Use a Client-Side Tool?
All previews are generated entirely in your browser. No data is sent to any server, which means you can safely test meta tags for unreleased pages, internal tools, and confidential projects without exposing URLs or content. The tool requires no account, works instantly, and generates standard HTML meta tags compatible with every website platform and framework.
Frequently Asked Questions
What is the recommended og:image size?
The recommended image size is 1200x630 pixels for Facebook and LinkedIn (1.91:1 ratio). For Twitter summary_large_image cards, 1200x600 pixels (2:1 ratio) works best. Using an image at least 1200 pixels wide ensures it displays at high quality across all platforms and devices.
What is the difference between summary and summary_large_image Twitter cards?
The "summary" card type shows a small square image thumbnail next to the title and description. The "summary_large_image" card displays a large banner image above the text, taking up more visual space in the feed. Large image cards generally achieve higher engagement and click-through rates for content with strong visuals.
Why does my shared link show the wrong image on social media?
Social platforms cache link previews aggressively. After updating your meta tags, you need to clear the platform cache. Use Facebook's Sharing Debugger, Twitter's Card Validator, or LinkedIn's Post Inspector to force a re-crawl. Also ensure your og:image URL is an absolute path starting with https:// and points to a publicly accessible image.
