Open Source ChromeOS Pixel Art Software

perfectPixel is a workflow tool for turning messy “pixel-style” images, especially those produced by generative models, into truly grid-aligned pixel art that reads cleanly at any scale. It tackles a common problem with AI pixel art: edges that look pixelated at first glance but are not actually aligned to a coherent pixel grid, which causes shimmer, blur, and uneven block sizes when you zoom in. The tool analyzes an image to infer the intended grid size, then refines and quantizes the artwork so pixels snap into consistent cells and the final result looks crisp and intentional. This makes it useful for game developers, sprite artists, and hobbyists who want to use AI-assisted ideation without shipping “almost pixel art” assets. It is designed to be easy to slot into an existing pipeline, whether you are batch-processing images or cleaning up a few key assets for a project.

NOIRADIX Studio is a free, open-source pixel art and sprite animation editor built around the structured PIX2 format. Draw and organize sprites with layers, regions, palettes, symmetry, rulers, and pixel tools. Preview 4-direction, 8-direction, Platformer 2D, and custom animation clips in real time. Edit PIX2 source directly or use an external AI coding assistant to create PIX2 content; the app does not generate artwork with AI. Import and slice raster spritesheets and metadata, then export PNG sheets, individual frames, TexturePacker-compatible JSON, or a Unity package with an atlas, metadata, and importer. The importer slices sprites and creates native .anim clips; Animator Controller setup is done in Unity. Runs in modern browsers without installation and supports offline workflows.

The goal of OpenPixel is to be an open source art program geared towards creating pixel art. It is written in Java and aims to be cross-platform and expandable via plug-ins.

The Pixel Art Construction Kit is a tool that allows people to easily build isometric stuff, manipulating their little cubes as Lego(TM) blocks. The tool is made by a lightweight core and some plugins that provide (hopefully) all the needed functions

A cross-platform sprite-based pseudo-3D isometric pixel art modeling aid. Written in 100% BlitzMax. Uses precise building blocks and a minimalist interface. Blocks snap to a grid aiding with precise construction. Can also save and load creations.
