Sprite Fusion Pixel Snapper

Online version: https://spritefusion.com/pixel-snapper

A tool to snap pixels to a perfect grid. Designed to fix messy and inconsistent pixel art generated by AI.

Why ?

Current AI image models can't understand grid-based pixel art.

• Pixel are inconsistent in size and position.
• The grid resolution can drift over time.
• Colors are not tied to a strict palette.

With Pixel Snapper:

• ✅ Pixel are snapped to a perfect grid.
• ✅ The grid resolution is consistent and can be scaled to pixel resolution.
• ✅ Colors are tied to a strict, quantized palette.

Perfect for

• AI generated pixel art that needs to be snapped to a grid.
• Procedural 2D art that doesn't fit a grid like tilemaps or isometric maps.
• 2D game assets and 3D textures that need to be perfectly scalable.

Pixel Snapper preserves as much details as possible like dithering.

Pixel Snapper comes in two flavors

Requires Rust installed on your machine.
