X Card Image Resizer

What matters

X Card Image dimensions at a glance

X card images appear when URLs are shared in tweets. The 1200×628 format matches the summary_large_image card type and fills the tweet card completely.

Links with proper card images get significantly more clicks than those showing a generic favicon or broken preview. This is your content's first impression.

Wrong dimensions result in cropped or letterboxed previews. Missing card images show a tiny favicon that's easy to scroll past.

Best practices

Use the crop intentionally

• Include a clear title or visual hook — card images compete with native image posts.
• Set up twitter:card meta tags with summary_large_image for maximum display size.
• Avoid small text — card previews are compressed and rendered at various sizes.
