Best-effort tool. Results depend on your input model's color data quality. Some color bleed or misclassification may occur, especially on models with subtle color transitions or very dark palettes. This tool works best with OBJ files that have clear, distinct color regions. We don't store your files — uploads are automatically deleted after processing.
