DeBabelizer offers three ways to reduce an image's color depth. Nolan Hester, author of DeBabelizer for Windows & Macintosh: Visual QuickStart Guide, shows you why only two ways offer you full control in selecting which colors are eliminated.

coverDEBABELIZER OFFERS THREE ways to reduce an individual image's color depth: by reducing its pixel (bit) depth, by reducing the number of colors it contains, or by applying a stand-alone palette.

Reducing the pixel depth of an image will cause colors to drop out of an image--without letting you control which colors are eliminated. By instead using the Reduce Colors command, DeBabelizer gives you a palette to pick the colors that are eliminated. It also lets you use dithering, which can use colors remaining in the palette to simulate colors you eliminate. Here's the pixel depth/color depth tradeoff: Changing the pixel depth is fast but imprecise since DeBabelizer may wind up creating a different palette for each image. If you're trying to shrink a group of related images, the Reduce Colors route gives you more control.

Note: In this lesson, Windows-only text items and figures are marked by  icon, while Mac-only features are noted by  icon. When menus for both versions appear in the same figure, the Windows version takes the left spot and the Mac version runs on the right, unless otherwise noted.
