Frequently asked questions
What is a Twitter card?
A Twitter card is a snippet of rich media—including a title, description, and thumbnail image—that attaches to tweets linking to your website. It improves engagement by making shared links visually appealing.
What is the difference between a summary card and a large image card?
A summary card features a small square thumbnail alongside the title and description. A summary card with large image displays a prominent, full-width header image designed to capture more visual attention in user feeds.
Why is my Twitter card image not showing?
Common causes include an incorrect twitter:image meta tag, an inaccessible image URL, or an image file format that does not meet platform size and dimension requirements.
Does this tool require an account or API key?
No, this browser-based tool is completely free to use and does not require an account, login credentials, or a developer API key.
How do Open Graph tags affect Twitter cards?
If specific Twitter card tags (like twitter:title or twitter:image) are missing, X automatically falls back to standard Open Graph tags (like og:title and og:image) to generate the preview.
