Image Dithering Tool

The Image Dithering Tool reduces a full-color image to a smaller color set while preserving perceptual detail, enabling halftone or low-color aesthetics. It quantizes toward a user-selected color depth and applies an algorithm to distribute quantization error across neighboring pixels. Conceptually, color values are snapped to a limited palette, and the difference (error) is propagated to surrounding pixels to minimize visible banding. This produces usable, stylistic images for legacy displays, print workflows, or artistic experiments. The tool supports Floyd–Steinberg, Jarvis–Juice–Nackman, Stucki, Atkinson, and Bayer (ordered) dithering, providing a spectrum from smooth diffusion to harsh lattice effects. Users can choose to preserve alpha or flatten the image, and define target color depth (2–256 colors). Typical use cases include asset creation for retro games, simplified textures for mobile apps, and stylized art that requires controlled artifact patterns. Core features include precise color-depth control, multiple algorithms, optional grayscale handling, and flexible output options. Outputs are deterministic and reproducible given the same inputs, enabling consistent pipelines for printers or game studios. The tool is beneficial for designers aiming to balance fidelity and file size, or to achieve specific halftone aesthetics without external software. It is suitable for single-file use or batch processing when processing multiple assets in a production line.
