Generate Twitter Card (X) meta tags with a live preview, so links look right when shared on X.

player and app cards also exist, but both need extra tags and, for player, allow-listing by X. They are out of scope here.

X falls back to Open Graph for anything the twitter: tags leave out, so with OG in place the only tag you strictly need is twitter:card. Tick this and the output drops to what actually earns its place — the duplicates are marked instead of emitted.

This is the documented card layout. X has changed how link previews render in the timeline more than once since 2023, and what you see there may be flatter than this — the tags below are still the ones X reads.

Tags

Paste the tags into the <head> of the page being shared. X caches cards, so a link that was already posted keeps its old card for a while — the new one shows up on a fresh share or once the cache expires. Two things this tool cannot check for you: that the page is reachable without a login, and that the image is under X’s 5 MB limit, which needs the file rather than its dimensions.

Overview

What is a Twitter Card Generator?

A Twitter Card Generator creates the twitter: meta tags that control how your link appears when shared on X (Twitter). You pick a card type, enter the title, description, and image, see a live preview of the card, and copy the tags into your page's <head> so X shows a rich preview instead of a plain link.

When a link is posted on X, the platform builds a card from your Twitter Card (twitter:) meta tags — a title, description, and image. Set them up and your link stands out; skip them and it appears bare.

This generator builds the twitter: tags and previews the card as you type, with a choice of compact or large-image layouts. It runs entirely in your browser, and the tags are yours to paste into your page's <head>.

Details

Card types, images, and Open Graph fallback

X supports two main card types: 'summary', a compact card with a small square thumbnail, and 'summary_large_image', a prominent card with a wide image — the one most publishers want. Each is declared with twitter:card, and the preview content comes from twitter:title, twitter:description, and twitter:image (which must be an absolute URL); twitter:site and twitter:creator add @handles for the site and author. A useful fact: X falls back to your Open Graph tags when the Twitter-specific ones are missing, so if you've already added og:title, og:description, and og:image, you get a basic card for free — but adding twitter: tags lets you control the card type and tailor the text for X. As with all social previews, X caches cards, so changes may take time or a fresh share to appear. Everything is generated locally in your browser. For the broader social tags, use the Open Graph Generator; for everything at once, the Meta Tag Generator.

Frequently Asked Questions

What is a Twitter Card?

A Twitter Card is the rich preview X shows when your link is shared — a title, description, and image instead of a bare URL. You enable it with twitter: meta tags in your page's <head>, choosing a card type that controls whether the image is a small thumbnail or a large banner.

What's the difference between summary and summary_large_image?

'summary' shows a compact card with a small square image beside the text; 'summary_large_image' shows a large, full-width image above the text — more eye-catching and better for articles and visual content. Pick large-image for most marketing pages; summary suits text-heavy or utility links.

Do I need Twitter Cards if I already have Open Graph tags?

Not strictly — X falls back to your Open Graph tags (og:title, og:description, og:image) when Twitter-specific ones are absent, so you'll get a basic card. But adding twitter: tags lets you set the card type and customise the text and image specifically for X, which is worth it for important pages.

What image size should I use?

For summary_large_image, use a wide image (around 1200×628, a 1.91:1 ratio); for summary, a square image works (at least 144×144, ideally larger). The image must be an absolute URL. Keep key content centred in case of cropping, and stay within X's file-size limits.

Why isn't my card showing on X?

Common causes: the image URL isn't absolute, the tags weren't present when the link was first shared (X caches the card), or the page blocks X's crawler. Make sure the tags are live, the image is publicly reachable, then post a fresh link — X re-fetches and builds the card when it can read the tags.

Where do I add the Twitter Card tags?

Inside the <head> of your page's HTML, alongside your other meta tags. In a CMS, use your theme header or an SEO plugin's custom-head field. They're read by X when your link is shared or crawled, so they need to be in place before you post.

Is it free, and do I need to sign up?

Yes, it's completely free with no account, no trial, and no limit on how many times you use it. Unlike most SEO suites, there's no login wall — it runs entirely in your browser, so you just open the page and use it.

Is my data private?

Yes. Everything is processed in your browser — whatever you type or paste is never sent to a server. Nothing is stored once you close the tab, so your URLs, content, and site details stay on your own device. That client-side approach is the core difference from cloud SEO tools.

Does it work on mobile?

Yes. It runs in your phone's browser with nothing to install, so you can generate or check markup on Android or iOS. The layout adapts to small screens, though pasting longer code is easier on a desktop.

Does it work offline?

Once the page has loaded, the work runs entirely on your device, so it keeps working without a connection. You only need to be online to open the page the first time — which is also why nothing you enter is uploaded.

Can I copy the output?

Yes. You can copy the generated code or results to your clipboard with one click, ready to paste straight into your site's HTML, CMS, or files. Because everything runs locally, copying is instant with no upload step.

Will this directly improve my rankings or get me into AI answers?

It produces correct, standards-compliant markup that helps search engines and AI engines (Google, AI Overviews, ChatGPT, Perplexity) understand your page clearly — which is a prerequisite for ranking and being cited. But it doesn't directly change rankings or guarantee a rich result or AI citation; those are decided by the engines based on your overall content and authority.
