When to Use Each Format

Here is a simplistic summary of the file format comparisons:
  • Use PNG-8 over GIF for images with simple colors (logos, icons, buttons)
  • Use PNG-8 over JPEG for images with simple colors (logos, icons, buttons)
  • Use PNG-24 over GIF for photographic images
  • Use PNG over JPEG when using alpha transparency
  • Use JPEG over PNG for photographic images
  • Use GIF for background transparency for older browsers (IE6 and below)
  • Use GIF for animated GIFs
