The preview uses supplied markup to approximate social cards. Platform layouts and cached results can differ from the example.
How to use the Open Graph Image Preview & Validator
- Paste your HTML. Copy the rendered page head and paste it into the tool.
- Review previews. Compare the supplied title, description and image across platform-style previews.
- Check the live page. Use each platform’s debugger to verify its actual crawl and cached preview.
Methodology
The tool parses pasted markup in the browser and renders illustrative card layouts.
Common use cases
- Reviewing social tags before publishing.
- Comparing an image and title in several card layouts.
Limitations and when not to use this
- The tool does not fetch or validate the page URL, image accessibility or platform cache.
- Actual platform previews may differ.
Frequently asked questions
Can this refresh a platform cache?
No. Use the platform’s own debugging tool to check and refresh its cached preview.
