🔍 What Is an Open Graph Preview Tool?
An Open Graph Preview Tool generates Open Graph (OG) and Twitter Card meta tags for your web pages and shows you exactly how your links will look when shared on social media platforms like Facebook, X (Twitter), LinkedIn, Discord, and Slack. OG tags control the title, description, and image that appear in link previews, and getting them right can significantly boost click‑through rates.
◆ This tool processes everything entirely in your browser — no data is ever sent to any server. Your metadata stays private and secure.
