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

For WordPress websites, the optimal image formats depend on the type of image and its use case:

  • JPEG/JPG – Best for photographs and complex images with many colors
  • PNG – Ideal for images requiring transparency or screenshots
  • WebP – Modern format that offers superior compression while maintaining quality
  • SVG – Perfect for logos, icons, and simple graphics that need to scale

To automatically convert and serve the best format, consider using the WebP Express plugin. This tool converts your existing images to WebP format and serves them to compatible browsers while maintaining fallback options.
