Balance between processing speed and output quality
| Method | Effect | Best For |
|---|---|---|
| No Dithering | Solid color blocks | Clean graphics, logos |
| Floyd-Steinberg | Natural error diffusion | Photos, gradients |
| Bayer (Ordered) | Regular pattern | Retro games, pixel art |
| Atkinson | Light diffusion | High contrast images |
Color reduction is the process of limiting the number of distinct colors in an image. It converts photographs with millions of colors down to a specific palette, useful for creating artistic effects, reducing file sizes, or meeting format requirements.
It depends on your goal: 2-16 colors create strong artistic effects, 32-64 colors work well for retro graphics, 128-256 colors maintain good quality while reducing file size. GIFs are limited to 256 colors maximum.
Dithering creates the illusion of more colors by mixing pixels of available colors. Use it when you want smoother gradients with limited colors. Skip dithering for clean, poster-like effects or when you want distinct color blocks.
Yes! After processing, you can export the resulting palette as hex codes, RGB values, or even as a palette image. This is useful for creating consistent color schemes across projects.
Often yes, especially for formats like GIF and indexed PNG that store palette information. However, the main purpose is artistic effect. For pure file size reduction, use our compression tool instead.
