Web Design: PNG-8 vs. PNG-24


PNG is an image format just like JPG or GIF. It was created to improve on and thereafter replace the GIF format. PNG’s come in a few formats, two of which are PNG-8 and PNG-24. What’s the difference?

PNG 8

  • Only 256 colors thus optimal in file size.
  • Use if the image consists of solid, even areas of color.

PNG 24

  • Millions of colors thus larger in file size.
  • Use if the image does not consist of solid, even areas of color since the type has more colors to work with and is subsequently superior in terms of color reproduction.

Note: Support varies from browser to browser and version to version. IE6 is particularly problematic but their exists various fixes for this issue online.

Everything’s obvious in hindsight, eh?
