Open Graph Tag Generator

Generates the Open Graph, Twitter Card, and canonical tags for a page, with an approximate preview of how it might look when shared. Validates URL, HTTPS, title/description length, and image alt text. It never visits the entered URL or downloads the remote image — all analysis is local.

Frequently asked questions

Is the preview identical to each social network's?
No. It's a visual approximation; each platform may truncate the text or cache the image differently from what's shown here.
Does it visit my URL or download my image?
No. The tool never makes any request to the URL or image you enter; it only validates the text locally.
