Frequently Asked Questions
Is the Page Title field required?
Yes. A title is the one field required to generate output, since it is used both as the page <title> and as a fallback for the Open Graph and Twitter title tags.
What if I leave OG Title or OG Description blank?
They automatically fall back to your main Page Title and Meta Description, so you don't need to duplicate the same text.
Which Twitter Card type should I use?
Use "summary_large_image" if you have a wide preview image (recommended for most content), or "summary" for a small square thumbnail preview.
Does this validate my URLs?
No, it does not verify that URLs are reachable, but it does HTML-escape special characters in every attribute value so the generated tags remain valid HTML.
Is my page content sent anywhere?
No. The meta tag block is built entirely in your browser using JavaScript. Nothing is uploaded or logged.
Can I download the result as a file?
Yes, click Download to save the generated tags as an .html file you can copy fragments from, in addition to the Copy button.
