Proper Pixel Art

Proper Pixel Art is a set of Python tools for cleaning up pixel art. It is built for imagery that has been upscaled, screenshotted, compressed or generated by AI tools, which rarely sits on a clean pixel grid. In such images cells drift out of alignment, edges blur, and colors that should be identical split into dozens of near duplicate shades. The approach described by the author is to recover the underlying pixel grid from the image itself and then snap the artwork back onto it. The result is output in which each logical pixel is exactly one image pixel, with a consistent and deliberate palette. It suits game artists, hobbyists and anyone who generates pixel style images with an image model and needs them to be usable as true resolution sprites or tiles. The project is published as a portfolio entry by Kenneth Allen, a data scientist with a PhD in mathematics, and it links to a GitHub repository holding the source code, usage instructions and before and after examples. It is a code project rather than a hosted web application, so there is no signup. No price is published, and the project page does not state a license. The listed address is the author's personal portfolio home page, and the tool itself lives on a project page beneath it.
