What’s the best image format to use for WordPress websites?

The optimal image format depends on the type of image and its use case:

  • JPEG/JPG: Best for photographs and complex images with many colors
  • PNG: Ideal for graphics, logos, and images requiring transparency
  • WebP: Modern format offering superior compression and quality
  • SVG: Perfect for logos and icons that need to scale

To handle multiple formats automatically, consider using the WebP Express plugin, which converts images to WebP format while maintaining fallbacks for older browsers.

For optimal results:

  • Use JPEG for blog posts and featured images
  • Choose PNG for graphics with text or transparency
  • Implement WebP with fallbacks
  • Use SVG for logos and icons
