Conversion Algorithm

K-Means Clustering

Iterative centroid grouping. Balanced, general-purpose.

Median Cut

Recursive colour-space splitting. Good for natural photos.

Resize & Pixelate

High-quality stepped downscale, each cell maps 1:1 to a resized source pixel.

Floyd–Steinberg Dither

K-Means palette with error-diffusion. Adds fine grain that simulates extra shades from few colours, great for shading with limited wood tones.

Ordered (Bayer) Dither

K-Means palette with a 4×4 threshold matrix. Produces an even, structured cross-hatch pattern, clean and repeatable for mosaic layout.
