Retro Game Graphics Maker works best when you start with a clear subject, a limited palette, and a target output size in mind. Fewer colors make shapes easier to read at small resolutions and help sprites, icons, and UI graphics stay crisp.
Before exporting, test several pixel sizes and compare silhouettes in the live preview. A slightly larger grid often keeps edges cleaner, while careful dithering can smooth gradients without making the final artwork muddy or blurry.
If your source image feels too busy, crop tighter and boost contrast before pixelating. Strong value separation, simpler forms, and fewer competing textures usually produce cleaner retro-style results and reduce the amount of manual cleanup afterward.
