Proper Pixel Art

Pixel art that has been upscaled, screenshotted, compressed, or generated by AI tools rarely sits on a clean pixel grid: cells drift off-alignment, edges blur, and colors that should be identical end up as dozens of near-duplicate shades. Proper Pixel Art is a set of Python tools for turning that kind of imperfect source imagery into clean, true-resolution pixel art.

The core idea is to recover the underlying pixel grid from the image itself, then snap the artwork back onto it — producing output where each logical pixel is exactly one image pixel, with a consistent, deliberate palette.
