Image Handling

Image sizes, aspect ratios, and format requirements for WhatsApp previews

Recommended image dimensions

1200 x 630 pixels at a 1.91:1 aspect ratio. Same as Facebook, since they share Meta’s crawling infrastructure.

Size-dependent display

WhatsApp picks a layout based on image width:

Image width Display
Below 100px No image, text-only preview
100-300px Small thumbnail beside the text
300px+ Full-width image above title and description

If you’re getting small thumbnails when you expect full-width, your source image is probably under 300px wide.

File size limits

Keep images between 300-600KB. No hard documented limit, but large images risk timing out during the crawl or loading slowly on mobile.

Supported formats

  • JPEG: photographs and complex images
  • PNG: graphics with text or transparency
  • WebP: supported and efficient
  • GIF: first frame only, no animation in previews

SVG is ignored. An SVG og:image produces a text-only preview.

Cropping

WhatsApp center-crops images that don’t match 1.91:1. Keep key text and visuals in the center 80% of the image.

Image URL requirements

  • Absolute URL (not a relative path)
  • HTTPS (HTTP images won’t load)
  • Publicly accessible without authentication
  • Not behind CDN hotlink prevention that blocks crawlers
