  • User Configurations


Display Considerations

  • Screen Sizes

  • Colors


Cross Platform/Browser-Safe Colors

File Formats

JPEG

  • Uses 16 million colors

  • Browsers use reasonable approximations

  • Work in RGB mode

  • Uses lossy compression

GIF

  • Best for solid color images (buttons, logos)

  • Uses 256 colors

  • Browsers uses 216 colors

  • Work in Indexed mode

  • Good compression

  • Interlaced

  • Used for transparent backgrounds


PNG (8-bit)

  • Best for line art (logos)

  • Compresses solid areas of color well and maintains sharp detail

  • Generally, has better compression than GIF (10-30% smaller)

  • If considering saving as GIF, also consider saving as PNG (8-bit)

  • Not supported by older browsers


PNG (24-bit)

  • Best for continuous-tone images

  • Compresses well, but can be larger than JPEGs

  • If considering saving as JPEG, could also consider PNG (24-bit)

  • Not supported by older browsers
