Frequently asked questions
How does palette swap work?
The tool extracts the most common colors in your sprite; you pick a replacement for each, and every matching pixel is remapped to the new color.
What dithering algorithms are supported?
Floyd–Steinberg error diffusion and ordered Bayer 4×4 and 8×8 dithering, or none for a hard threshold. Dithering works with your swapped colors or with a preset palette.
Which retro palettes are included?
1-bit black & white, the four Game Boy greens, CGA (black, cyan, magenta, white) and 4-level grayscale, with a pixel-size slider for a chunkier look.
Does it keep transparency?
Yes. Transparent pixels are left untouched and never receive dithering error, so sprite edges stay clean.
