About this tool

IconVault's Image Dithering turns photos into retro pixel-art style images with real dithering algorithms: Floyd-Steinberg error diffusion, ordered Bayer (4x4 and 8x8 matrices) and Atkinson dithering. Pick a classic palette like 1-bit black and white, Game Boy greens or CGA colors, and watch smooth gradients dissolve into beautiful dot patterns.

Processing happens entirely in your browser on an HTML canvas, with no upload and no signup, and it is free. Honest note: dithering is destructive by design; keep your original file, because the effect cannot be reversed from the exported image.
