Convert OBJ to GLB Online — Web-Ready 3D Models

Convert your OBJ 3D models to GLB format for Web3D, augmented reality (AR), and virtual reality (VR). GLB is the binary container for glTF 2.0, the modern standard for real-time 3D rendering on the web.

GLB is natively supported by Three.js, Babylon.js, WebXR, Google's model-viewer, and AR frameworks. Convert locally in your browser using WebAssembly — no upload, no server delays, instant download.

Perfect for web developers, AR/VR creators, e-commerce 3D product displays, and anyone bringing traditional 3D assets into the modern web ecosystem.

Technical Details

What Changes During Conversion

Converting OBJ to GLB is relatively low-loss. Geometry is fully preserved. UV texture coordinates are preserved. OBJ's simple Phong/Blinn materials (.mtl) are approximated as PBR materials. If quads or n-gons exist, they are triangulated for GLB. This converter preserves UV mappings but MVP does not support multi-file uploads (OBJ + textures).

Why GLB Over GLTF

GLB is the binary container format -- a single file with everything embedded. It loads faster (one HTTP request), is more compact (binary encoding), and is easier to deploy. Use GLTF only for debugging (human-readable JSON). Always use GLB for production.

Common Use Cases

Web3D Visualization

Display models on your website using Three.js or Babylon.js. Visitors can rotate, zoom, and inspect the model in their browser.

AR/VR Content Creation

GLB is the standard format for WebXR experiences. Use GLB to build cross-platform AR/VR apps that run on Meta Quest, HoloLens, iOS Safari AR, and Android Chrome AR.

E-commerce 3D Product Displays

Shopify, WooCommerce, and custom e-commerce sites can embed interactive 3D product viewers using GLB with Google's model-viewer component.

Frequently Asked Questions

GLTF is the JSON-based format (.gltf + .bin + textures). GLB is the binary container that packages everything into a single .glb file. GLB is faster to load on the web (one HTTP request). Always use GLB for production.
Yes! Load it with GLTFLoader. If the model looks flat, add directional lighting or environment maps (IBL). glTF uses PBR materials that require proper scene lighting.
Partially. OBJ uses Phong/Blinn materials. GLB uses PBR. Diffuse color maps to base color, specular is approximated as roughness. For best results, manually assign PBR materials in Blender.
Lighting. glTF uses PBR, which requires proper scene lighting. If your Three.js scene has only ambient light, the model will look flat. Add directional lighting or use environment maps.
No. OBJ doesn't support animations. The GLB will be a static model. If you need animated GLB, start from FBX or export from Blender with armature and animations.
