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 handle WebP conversion automatically, consider using WebP Express. This plugin can convert your existing images to WebP format while maintaining the original files as fallback.
