Build summary and summary_large_image card tags for X
Runs in your browser. Nothing you type is sent anywhere. Updated on 24 Oct 2026.X builds its link card from twitter: tags and falls back to Open Graph when they are missing. Choose summary for a small square thumbnail or summary_large_image for the wide banner, add the site and author handles, and copy the block. The preview here uses the same order X does, so you can see which tag is actually being used for each line of the card.
The page opens with the X (Twitter) tags shown on the right.
Under X card type, choose Large image for the wide banner or Small summary for a square thumbnail.
Press More options and fill in the X site handle and X author handle.
Press X (Twitter) under Shared link card to preview the card X would draw.
Press Copy to take the twitter: tag block for the head of your page.
This meta tag generator writes the block of HTML that goes in the head of a page: title, description, canonical, robots, Open Graph and Twitter card tags. You fill in plain fields, and the finished markup appears next to a preview of the Google result and the share card each network would draw from it.
Most people reach for it in two situations. The first is a new page on a hand-built site or a static site generator, where the head has to be written once and correctly. The second is a page that shares badly: the link looks like a bare URL in WhatsApp, or Google prints a sentence nobody wrote. Seeing the preview usually shows the cause in a few seconds, which is normally a relative og:image path or a missing canonical.
The checks are the ones that matter, not a long score sheet. The tool counts characters against the lengths search results and cards actually display, insists that a canonical and an og:image are absolute addresses, and says when summary_large_image has no picture to show. Everything runs in your browser, so an unreleased page title never leaves your laptop.
The rest of the article, and all 6 questions about Meta Tag Generator, are on the Meta Tag Generator page.
No. Google stopped using the keywords meta tag in 2009 and Bing treats it as a spam signal. This generator does not write one. Put your keywords in the title, the description and the page text instead, where they are actually read.
Almost always a missing or relative og:image. Networks fetch the image from their own servers, so the address must be absolute and publicly reachable. Facebook and LinkedIn also cache old cards, so refresh them in their debugger after fixing the tag.
X falls back to og: tags when twitter: tags are missing, so the og block alone works. Add twitter:card if you want the wide image, and twitter:site or twitter:creator if you want the account credited on the card.
No. The tags are built in your browser with JavaScript. Nothing is sent to a server, so you can draft the head of an unreleased page or an internal site without it leaving your device.
