Posterize ramps adapt their colors to your texture's tones

Build your own palettes with the custom palette editor, save them in the app, and export any palette to an external file (.palette.json). Import palettes back from JSON, hex, or plain-text files

Features

• Image + model input: drop a PNG/JPG/WebP/GIF texture, or a 3D model bundle (FBX, OBJ, glTF/GLB, USDZ plus companion textures).
• Pixelation: target resolution from 24 to 2048 px (2K).
• Pattern: Floyd-Steinberg, Atkinson, Ordered 4×4, Halftone, Cross, Stripes, Noise, Checker, and Hard map (no diffusion).
• Palettes: 47 built-in palettes — including 8 Posterize ramps (2–16 levels) whose colors are derived live from your BaseColor — plus a custom palette editor with import/export.
• Adjustments: brightness, contrast, and saturation.
• 3D preview: orbit the model with baked lighting applied; choose UV channel, LOD level, and world axis.
• Baking: generate ambient occlusion, bake lighting into UV space, and apply normal maps.
• UV overlap visualization: an animated glow wave highlights overlapping UV shells.
• Export: save the dithered result as a PNG, and save/load settings as JSON.
