To Pixel Art Tools

Turn images into pixel art without leaving Unity.

To Pixel Art Tools is a native C# conversion toolkit for artists and developers who need controlled, repeatable pixel art results from illustrations, renders, photos, sprites, icons, backgrounds, and animation frames.

Work interactively in a dedicated Editor window, compare the source and result through a live preview, fine-tune the look, and save the converted image with pixel-art-friendly import settings.

FAST VISUAL WORKFLOW

- Drag an image into the conversion window or select it from the Project window.

- Start from one of seven built-in presets.

- Preview changes without exporting after every adjustment.

- Zoom, pan, enable a pixel grid, or compare the source and result with a draggable divider.

- Convert and save directly into the project.

FULLY CUSTOMIZABLE PIPELINE

The conversion pipeline contains six reorderable stages:

- Smooth

- Background Removal

- Pixel Art

- Despeckle

- Outline

- Diffuse

Moving a stage before or after the Pixel Art step changes whether it processes the full-resolution source or the final pixel grid, giving you direct control over the resulting style.

CONTROL RESOLUTION, COLOR, AND TEXTURE

Choose between Nearest, Box, and perceptual LAB Average downscaling. Build palettes using K-Means, Median Cut, or a fixed palette asset.

Add organic Floyd-Steinberg dithering or ordered 2x2, 4x4, and 8x8 Bayer patterns. Additional controls include run merging, color transfer, alpha thresholding, sharpening, background edge cleanup, outline generation, and painterly diffusion.

BUILT FOR PRODUCTION WORKFLOWS

- Batch-convert multiple textures or complete folders.

- Share one palette across related assets for visual consistency.

- Automatically detect numbered animation frames.

- Convert animation frames against one shared palette to reduce color shimmer.

- Save complete configurations as reusable profile assets.

- Create, import, export, sort, and extract color palettes.

- Automatically apply point filtering, uncompressed textures, disabled mipmaps, and optional sprite settings.

EDITOR AND RUNTIME

The complete conversion pipeline is also available through a public runtime API. Convert individual Texture2D assets or animation sequences synchronously or asynchronously, with progress reporting and cancellation support.

The algorithm core uses a plain RGBA pixel buffer and does not depend on Editor APIs.

NO EXTERNAL WORKFLOW

No Python, command-line tools, native plugins, generative AI, external executables, third-party packages, internet connection, or cloud service is required. The complete implementation is included as C# source code and runs locally inside Unity.

Suitable for 2D RPGs, platformers, roguelikes, strategy games, retro-inspired projects, stylized backgrounds, UI icon sets, texture processing, and custom asset pipelines.

Includes a ready-to-open demo scene, seven presets, scripting examples, offline HTML and Markdown documentation, and a detailed troubleshooting guide.
