AI Normal Map Upscaler
Increase a tangent-space normal map to four times its width and height with processing designed specifically for normal-map detail.
Generation Queue
What this tool does
Unlike a general color-image upscaler, the Normal Upscaler is designed for normal maps and preserves their directional surface information during enhancement. It exports a 16-bit PNG and offers seamless processing for tileable materials.
- Create an exact 4x normal-map output
- Preserve normal-map surface detail
- Process tileable normals with seamless enhancement
How to use it
- 1Upload an RGB tangent-space normal map.
- 2Choose whether the texture should be processed seamlessly.
- 3Generate and download the 16-bit x4 normal map.
Frequently asked questions
Why use a dedicated normal-map upscaler?
Normal maps store specialized surface information rather than ordinary color. A dedicated upscaler preserves that information more reliably than a general photo or texture upscaler.
What resolution will the output have?
The output is exactly four times the input width and four times the input height. A 1024 by 1024 input becomes 4096 by 4096.
Does the tool change OpenGL normals into DirectX normals?
No. It preserves the orientation encoded by the input. Use the same OpenGL or DirectX convention in the output as in the uploaded map.
