Sprite Fusion Pixel Snapper
Sprite Fusion Pixel Snapper is a free, open-source tool for cleaning messy or blurry pixel art and snapping it to a clean pixel grid. Browser and desktop versions available, with PNG export.
Overview
Sprite Fusion Pixel Snapper is a free, open-source tool for cleaning up pixel art that is messy, blurry, or off-grid. It takes an uploaded image and snaps the pixels into a more regular pixel grid, with the goal of making imperfect pixel art easier to use.
The product is aimed at AI-generated pixel art as well as hand-drawn images that need cleanup. The docs note that it works best when the source is already close to pixel art, and the interface lets you choose an output color count before downloading the corrected image as a PNG.
Features
Color-count control
Adjust the output palette from 8 to 64 colors to better handle noisy source images, gradients, dithering, or subtle ramps.
PNG output
Download the processed result as a PNG after the pixels are fixed and the image is re-saved.
Detail preservation
Designed to preserve details such as dithering and curves instead of flattening the image into a generic filter effect.
Multiple deployment options
Available as a browser version, a standalone desktop edition, a CLI from the open-source project, and a WASM module for web integration.
Desktop availability
The desktop edition is described as offline, open source, and supported on Mac, Linux, and Windows.
Use Cases
AI-generated pixel art cleanup
Clean up AI-generated pixel art that has uneven edges, blurry pixels, or off-grid color placement before using it in a game or mockup.
Hand-drawn sprite cleanup
Convert hand-drawn pixel-style images into a more consistent grid when the original artwork needs a tidier base.
Game asset preparation
Prepare sprites, tilesets, tilemaps, or 2D textures that need crisp pixel-perfect scaling in downstream tools.
Batch processing on desktop
Use the desktop edition when you want offline batch processing for repeated cleanup jobs on multiple images.
