Question 1

What is a Threads or Twitter/X Card?

Accepted Answer

When you share a URL on Threads or X (Twitter), the platform automatically generates a card preview showing the page's image, title, and domain. Threads and X both read this from your page's Open Graph and Twitter Card meta tags. This tool lets you see exactly how that card will look before you post.

Question 2

Is this a Twitter Card validator too?

Accepted Answer

Yes. This tool checks both Open Graph tags (used by Threads and most platforms) and Twitter Card meta tags (twitter:card, twitter:title, twitter:image) — falling back to whichever is present, and showing the detected Twitter/X card type when available.

Question 3

Why does my link card show the wrong image?

Accepted Answer

The image comes from your page's og:image or twitter:image meta tag. If the image is wrong or missing, check that your page has one of those tags set to a publicly accessible URL. The recommended size is 1200x630 pixels.

Question 4

How do I fix my link card preview?

Accepted Answer

Update the Open Graph and/or Twitter Card meta tags on your page (og:title, og:image, og:description, twitter:card, twitter:image). After updating, it may take some time for Threads or X to refresh the cached preview. Use this tool to verify your changes look correct.

Question 5

Is this Link Card Validator free?

Accepted Answer

Yes, completely free — no login and no account required, for both Threads and Twitter/X card previews.
