What this tool is for
Generate a reviewable set of Open Graph and X/Twitter metadata tags from a page title, description, URL, image URL, and card choice. It does not fetch or validate the remote image.
How to use
- Enter canonical absolute page and image URLs.
- Add accurate title and description text.
Generatethe tags, inspect escaping and card type, then test the deployed page with platform debuggers.
Example
Generate tags for an article URL and a 1200x630 HTTPS image, then confirm the final deployed HTML contains only one canonical value for each property.
FAQ
Does the generator upload my image?
No. It only writes tags containing the URL you provide.
Why can a platform show an older image?
Social crawlers cache previews; use the platform's debugger after deployment.
