About the Open Graph/Twitter Card Preview Online Free Tool

The Open Graph/Twitter Card Preview Online Free Tool reads social metadata from a URL or pasted HTML and builds a quick report for titles, descriptions, images, canonical URLs, card type, and site name. It helps catch missing or mismatched social sharing tags before publishing.

How to Use the Open Graph and Twitter Card Preview Online

1. Enter a page URL to fetch metadata, or use advanced mode and paste HTML directly.
2. Generate the preview.
3. Review the Open Graph and Twitter card panels.
4. Copy the metadata report for QA notes or implementation fixes.

Choosing Options Correctly

Use pasted HTML when testing unpublished pages, staging output, or local templates. Use a URL when checking what the live page currently exposes to crawlers.

Common Use Cases

• Audit launch pages before social sharing.
• Compare Open Graph and Twitter card fields.
• Check whether image and canonical URLs resolve as absolute values.

Quick FAQ

Does this guarantee the exact preview on every platform?
No. Social platforms apply their own caches, crops, and rendering rules, but this helps verify the metadata they read.

Can I test unpublished HTML?
Yes. Paste the HTML in advanced mode and provide a base URL when relative image or link paths need resolving.

Why does the live platform still look wrong?
The platform may be using a cached card. Refresh the card in the platform debugger after fixing title, description, image, or URL tags.

Is pasted HTML sent anywhere?
No. Pasted HTML is parsed in the browser. URL fetch mode asks the site utility endpoint to retrieve the public page.
