Graphic File Comparison

Interlaced GIF
  • 256 color
  • 42K
Some images appear to drift onto the page in layers, this is because they are interlaced. This is part of the gif89a specification. Only GIF's can be interlaced.
    Regular GIF
    • 256 color
    • 40K
    0% Compression JPEG (original)
    • 16.7 million color
    • 52K
    50% Compression JPEG
    • 16.7 million color
    • 11K
    Transparent GIF
    • 256 color
    • 8K
    		Another special trick is to make part of an image appear transparent so that the browser background color shows through an image. Transparency and interlacing are GIF file format options that can be controlled using software.
    Animated GIF
