Grid guide vs pixel art
Pixel Grid Guide outputs a craft blueprint: fixed 32×32 or 64×64 cells, numbered palette indices, and a readme for beads or thread. Pixel Art focuses on retro aesthetics — adjustable block size, game palettes, and optional dithering for screen art.
Use this tool when you need a paint-by-number sheet. Use Pixel Art when you want a stylized PNG for avatars, wallpapers, or game mock-ups.
