What Normal Map Generator does

Normal Map Bench is a browser-based tool that converts height map textures (PNG, JPG, or WebP) into tangent-space normal maps entirely on your machine. The output is a single normal map file ready for use in 3D projects. Users receive a generated normal map that preserves surface detail from their source height map, with no account required and no files uploaded to a server, ensuring complete privacy. The tool is designed for game developers, 3D artists, and graphics programmers who need to convert height maps into normal maps for 3D models and games. A real-time 3D preview with live lighting lets you visualize how the generated normal map renders on geometry before downloading. Adjustable strength and smoothing controls allow fine-tuning of the conversion quality to match your needs. The entire process runs locally in the browser, meaning no account, no file uploads, and no privacy concerns. It is a lightweight, accessible solution for anyone needing to generate normal maps quickly and securely. The interface focuses on simplicity while providing enough adjustment options to refine the result without leaving the browser tab.
