How to Fix AI-Generated Pixel Art | Pixel Snapper

Open Source

Convert AI pixel art into clean, grid-aligned pixel art while preserving the original shapes and details.

Workflow to clean up AI-generated pixel art

From AI mixels to a clean pixel art

AI image models often produce blurry, inconsistent, off-grid pixels. Pixel Snapper finds the underlying grid and rebuilds the image on a consistent pixel grid.

1. Quantize colors

Read the color of every source pixel

Blurry AI-generated pixel art with uneven pixel sizes

Find representative colors

Four representative green and yellow colors selected with K-means

Build a limited, consistent palette

AI-generated pixel art reduced to a consistent green and yellow palette

2. Edge profiles

Measure the strength of each brightness change

Find the median gap between peaks

3. Walk cuts

Set the expected distance between cuts

Horizontal and vertical spacing guides over quantized pixel art

Follow the strongest nearby edge peaks

Grid lines adjusted to follow the detected edges in the pixel art

4. Resampling

Use each cell as a color voting area

Detected grid dividing the source image into color-voting cells

Keep the winning color from each cell

Resampled pixel art with one palette color assigned to each output cell

Result
