About Twitter Card Preview
The Twitter Card Preview tool shows you how a page will look when its link is shared on Twitter/X, built entirely from the twitter:card meta tags you supply.
Enter the card type, title, description, image URL and your @site handle, and the tool renders a faithful mock of the resulting card while generating the exact meta tags you can paste into your page head.
It is the fast way to check your social markup before publishing, without posting a test tweet.
Twitter supports two main layouts and the preview reflects both.
The summary card is compact, with a small square thumbnail beside the title and description, while summary_large_image gives the photo a full-width banner above the text — the format you want for articles and visual content.
The tool warns you when a large-image card has no image (Twitter then quietly downgrades it), when an image URL is not an absolute http or https link, and when titles or descriptions run past the lengths Twitter truncates at.
Handles are normalised to a single leading @ and validated against Twitter username rules, and the page URL is parsed to display the domain just as the real card does.
Nothing is fetched from the network — the preview is modelled purely from your inputs, so it works for staging URLs and private pages too.
Everything runs locally in your browser, so your content is never uploaded.
FAQ
What is the difference between summary and summary_large_image?
Summary shows a small square thumbnail next to the text; summary_large_image puts a full-width image above the title and description, ideal for articles and visual posts.
Does this tool fetch my page?
No. The preview is built only from the values you type, so it never makes a network request and works for staging or private URLs.
Why does my large-image card show a warning?
A summary_large_image card needs a valid absolute image URL. Without one, Twitter falls back to a small summary card, so the tool flags it.
