About the summary_large_image card
A Twitter card turns a plain link into a rich post with a title, description and image. The summary_large_image type shows a wide, prominent image above the headline - ideal for articles, product pages and landing pages where the visual matters. The generator writes twitter:card, twitter:title, twitter:description and twitter:image for you to paste in.
A few honest notes: this tool only produces markup - it does not fetch, scan or upload your site, and everything stays in your browser. The preview is an approximation of how X renders cards, and X caches previews, so after publishing you may need to share or re-share the link for the new card to appear. X also falls back to your Open Graph tags for some values, so it's worth generating both. Host the image yourself; 1200x630 works well for the large-image card.
Frequently asked questions
What is summary_large_image?
It's the Twitter card type that displays a large, full-width image with your title and description, rather than a small thumbnail.
Does this tool test my live card on X?
No. It only generates the tag markup from your input. It does not connect to X or upload anything - everything runs in your browser.
Do I need Open Graph tags too?
It helps. X reads Twitter Card tags first but falls back to Open Graph for some fields, so having both gives the most consistent preview.
My card isn't updating on X - what do I do?
X caches link previews. Re-sharing the URL usually refreshes it; the preview here is only an approximation of the final result.
What image size should I use?
Host a 1200x630 image yourself for the summary_large_image card. That ratio displays cleanly in the X timeline.
