ℹ️ About Open Graph Checker
The Open Graph Checker is a free developer tool built for speed and privacy. Preview how your URL looks when shared on Facebook, Twitter, LinkedIn and Slack. Check Open Graph and Twitter Card meta tags. Every operation runs entirely in your browser, which means your code, text, or payload is never uploaded to a server. Paste your input, hit the button, and get the output — formatted, validated, or transformed — in milliseconds. This Open Graph Checker is designed to replace slow, bloated web apps with a single focused page that loads fast, works offline after first visit, and handles both small snippets and large inputs gracefully.
💡 Use Cases
💎 Pro Tips
- Paste your content directly — the Open Graph Checker detects common input patterns and applies sensible defaults automatically.
- Use keyboard shortcuts (Ctrl/Cmd+A to select all, Ctrl/Cmd+C to copy) to speed up your workflow inside the Open Graph Checker.
- For very large inputs, break them into chunks — most browser tabs can handle megabytes of text, but parsing huge payloads may freeze the UI briefly.
- The Open Graph Checker does not log or store your input. If you need history, copy important outputs to a local file or note app.
- Combine the Open Graph Checker with other tools on this site (formatters, converters, encoders) to build complete data pipelines without leaving your browser.
