How to Generate Normal Maps Online

This Normal Map Generator allows you to create high-quality normal maps from any image or texture directly in your browser. Normal maps are essential in 3D game development for adding detail to surfaces without increasing the polygon count.

  1. Upload your image: Drag and drop your texture or click the "Upload Image(s)" button.
  2. Adjust settings: Use the sliders to control bump strength and invert channels if needed.
  3. Preview in 3D: See your normal map applied to a 3D model (Cube, Sphere, or Plane) in real-time.
  4. Download: Save your generated normal map instantly.

What is a Normal Map?

A normal map is a type of texture used in 3D computer graphics to simulate lighting bumps and dents. Each pixel in the RGB map corresponds to a standard XYZ vector, telling the game engine which direction the surface is facing at that point.

Why use this tool?

  • Free & Unlimited: No credits or paywalls.
  • Batch Processing: Convert multiple textures at once.
  • Local Processing: Uses WebGL to render normal maps directly on your GPU.
