PIXATTO

PIXATTO is a desktop texture tool for turning PNG, JPG/JPEG, BMP, TGA, GIF, WebP, JPEG XL, QOI, TIFF, and PNM/PPM/PGM/PBM images, plus GLB, glTF, OBJ, FBX, and DAE model textures, into pseudo-pixel art and palette-constrained assets.

It is built for quick iteration: import an image or model, tune the pixel size and color treatment, save reusable presets, batch process image sets, preview the result live, then export compact PNG, raw indexed image data, or processed model textures when it looks right.

Features

• Block pixelization with linear-light averaging
• Palette mapping with bundled Lospec palettes and greyscale ramps
• Import custom Lospec .hex palettes
• Create, edit, save, duplicate, and delete palettes inside the app
• Up to 256 palette colors, with optional single-bit transparency preservation
• Bayer, blue-noise, Floyd-Steinberg, Jarvis-Judice-Ninke, Atkinson, Stucki, Burkes, Sierra, Two Row Sierra, Riemersma, and additional pattern dithering modes
• Brightness, contrast, gamma, levels, saturation, and tint controls
• Save, apply, overwrite, and delete processing presets
• Batch pixelize multiple images to PNG or raw indexed output
• Single-result, side-by-side, and stacked preview layouts
• Undo and redo for processing edits
• Drag-and-drop image, palette, GLB/glTF, OBJ, FBX, and DAE imports
• Unshaded OpenGL model preview for checking processed textures directly on meshes
• Material list and texture drawer for assigning imported images to model materials
• Original/result model texture gallery previews for comparing source and processed textures
• Orbit, pan, zoom, reset, and origin controls for the model preview
• PNG export, including indexed 8-bit PNGs when possible
• Raw indexed export with shared .pal palette sidecars and optional .msk transparency masks
• Windows, Linux, and macOS builds

What's new in 1.7.0

• Batch pixelize workflow for processing multiple images with the current settings or a saved preset
• Saved processing presets for reusing favorite pixelization, palette, dithering, and adjustment setups
• Expanded image imports through SDL_image: TGA, GIF, WebP, JPEG XL, QOI, TIFF, and PNM/PPM/PGM/PBM files
