If you zoom into most AI-generated pixel art, it falls apart.
What looks like pixel art is often just a pixel-art-like image:
- blurry borders
- anti-aliased edges
- inconsistent grid spacing
- multiple colors inside what should be a single pixel cell
That makes it frustrating for indie game developers, RPG Maker creators, and pixel artists who want something they can actually use.
So I built MonoPix.
The problem: AI pixel art is usually fake
The issue isn’t just quality.
The issue is structure.
Real pixel art is built on a clean, consistent grid.
A lot of AI-generated “pixel art” only imitates the appearance of that structure.
It looks right from far away.
It breaks the moment you inspect it closely.
What MonoPix does
MonoPix has a mode called Snap.
Instead of just resizing or filtering the image, Snap tries to reconstruct the underlying pixel grid:
- detect the likely grid spacing
- align cuts to actual edges
- rebuild each cell with one clean color
- preserve transparency
The result is much closer to real, editable pixel art.
Why I made it browser-only
I wanted it to be frictionless:
- no server
- no account
- no upload
- no API cost
- no waiting
You open the app, drop an image, and process it locally in your browser.
Open source and free
MonoPix is:
- 100% free
- MIT licensed
- fully open source
If you want, you can fork it, self-host it, or inspect the algorithm.
Under the hood
The Snap pipeline roughly works like this:
- color quantization
- edge profile analysis
- periodic step estimation
- elastic grid walking
- cell-wise RGBA majority voting
That helps recover a clean grid even when the source image has blurry boundaries or uneven scaling artifacts.

If you work on indie games, RPG Maker projects, sprites, or pixel-art cleanup workflows, I’d love to hear what breaks and what’s missing.
