What are the best image formats to use for WordPress websites?

Choosing the right image format is crucial for optimization. Here are the recommended formats:

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

To automatically convert images to WebP format, consider using the WebP Express plugin. This plugin can automatically serve WebP images to compatible browsers while maintaining fallback options for older browsers.
