Architectural Visualization
Transform material samples and surface textures into professional normal maps for realistic building materials, flooring, and wall textures in architectural renders.
Web Development
Create lightweight normal maps for WebGL applications, Three.js projects, and interactive web experiences that need realistic lighting without heavy geometry.
VR/AR Applications
Optimize performance in virtual and augmented reality by using normal maps instead of high-poly geometry while maintaining visual fidelity and realistic lighting.
Texture Production Pipeline
Streamline your PBR (Physically Based Rendering) workflow by quickly converting height information into normal maps for complete material sets.
Frequently Asked Questions
What is a Normal Map Generator?
A normal map generator is a tool that converts height maps (grayscale images representing surface elevation) into normal maps. Normal maps are special textures that simulate surface details like bumps, scratches, and grooves in 3D graphics without adding actual geometry. They use RGB color data to represent surface normal directions, creating the illusion of depth and detail under different lighting conditions.
How do I use this Normal Map Generator?
Using the tool is simple: drag and drop your height map image into the upload area, or click to browse and select a file. Once uploaded, adjust the intensity, scale, and blur parameters to achieve the desired result. You can also invert the X or Y axes if needed. The normal map generates in real-time as you adjust settings, and you can download it instantly when satisfied with the result.
Is this Normal Map Generator free to use?
Yes, this normal map generator is completely free to use with no limitations. There are no watermarks on generated images, no registration requirements, no usage limits, and no hidden fees. All processing happens locally in your browser, so you don't need to worry about subscription costs or per-use charges.
What image formats are supported?
The tool supports all common image formats including PNG, JPG, JPEG, BMP, and WEBP. For best results, use high-contrast grayscale height maps where white represents the highest points and black represents the lowest points. The maximum file size is 10MB, which accommodates most texture resolutions used in game development and 3D modeling.
Are my images uploaded to your servers?
No, your images are never uploaded to our servers. All image processing is done locally in your browser using HTML5 Canvas and JavaScript. This ensures complete privacy for your textures and assets, faster processing since there's no upload time, and the ability to work offline once the page is loaded. Your images never leave your computer.
What are the recommended settings for Unity?
For Unity normal maps, use medium intensity (0.5-1.0) to avoid over-exaggerated effects, keep scale at 1.0 unless you need to compress or expand details, and ensure the output format is PNG for transparency support. After importing into Unity, remember to set the texture type to "Normal Map" in the inspector and check "Create from Grayscale" if starting from a height map.
Can I batch process multiple images?
Currently, this tool processes one image at a time to ensure optimal performance and real-time preview capabilities. However, you can quickly process multiple images by using the "New Image" button after downloading each result. The settings you configure will remain active, making it easy to maintain consistency across multiple textures in your project.
What's the difference between height maps and normal maps?
Height maps are grayscale images where brightness values represent surface elevation - white for high areas, black for low areas. Normal maps are RGB images that encode surface normal directions using color channels (red for X-axis, green for Y-axis, blue for Z-axis). While height maps show "how high," normal maps show "which direction" the surface is facing, providing more detailed lighting information for 3D rendering.
