GLB Optimization for the Web: Reduce File Size Without Losing Quality
Practical GLB optimization steps for balancing geometry, textures, animation and compression in web 3D projects.
GLB is useful for web 3D because it can package geometry, materials, textures and animation in one file, but desktop-ready assets can become too heavy for mobile browsers.
Start by removing hidden geometry and unnecessary subdivisions while protecting the silhouette. Review texture resolution according to real screen usage and keep only the maps that contribute visibly. Animated assets should exclude unused actions, excessive keyframes and invisible objects.
On the web, loading strategy matters too: poster images, lazy loading, camera defaults and loading the model only when the user reaches the 3D section can improve perceived performance. Optimization is about finding the right balance between load time and visual quality.
