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

The optimal image format depends on the type of image:

  • WebP: Best overall format for web images, supported by most modern browsers
  • JPEG: Ideal for photographs and complex images with many colors
  • PNG: Best for images requiring transparency or screenshots
  • SVG: Perfect for logos and icons that need to scale

Consider using the WebP Express plugin to automatically convert your images to WebP format while keeping fallback versions for older browsers. This ensures optimal performance across all devices and browsers.
