What it does

A browser-based converter for mapping 2D image data to 3D geometry

Why it's useful

Img2STL processes bitmap images to calculate depth based on luminosity, generating a three-dimensional STL mesh. The output represents tonal values as physical contours, translating image files into geometric data for additive manufacturing. Because the conversion occurs locally within the browser, it avoids the latency of server-side processing. This workflow offers a direct path from pixel-based input to structured spatial geometry.
