Convert OBJ to GLB
Convert a OBJ file to GLB in your browser. Free, no upload, no sign-up.
Convert OBJ files to GLB directly in your browser. The converter parses the OBJ mesh, rebuilds it in memory and writes it out as GLB, keeping every triangle. Nothing is uploaded, there is no file size limit beyond your computer's memory, and the result downloads instantly. GLB is the format web browsers, AR viewers and e-commerce platforms expect; one self-contained file with materials included.
How to convert OBJ to GLB
- 1Drop your OBJ file
Drag a .obj file onto the box above or click to choose one. The companion .mtl file and textures are ignored. Geometry is imported completely.
- 2Check the preview
The model renders in 3D so you can confirm it loaded correctly. Dimensions, volume and triangle count are shown next to it; open edges are flagged if the mesh is not watertight.
- 3Download the GLB
Adjust the export options if needed and click download. Meshes without materials get a neutral gray PBR material so the file renders correctly in viewers.
What is a OBJ file?
OBJ is a plain-text mesh format from Wavefront. It stores vertices, normals, UV texture coordinates and face definitions, and references materials through a companion .mtl file. It is human-readable and supported by virtually every 3D modelling application.
Commonly used by: Blender, Maya, ZBrush, game engines, photogrammetry tools
The companion .mtl file and textures are ignored. Geometry is imported completely.
What is a GLB file?
GLB is the binary container for glTF 2.0, the "JPEG of 3D" maintained by the Khronos Group. A single .glb file bundles geometry, PBR materials, textures and animations, and is the standard format for 3D on the web and in AR viewers.
Commonly used by: web viewers (three.js, model-viewer), AR on iOS and Android, Sketchfab, game engines
GLB is the format web browsers, AR viewers and e-commerce platforms expect; one self-contained file with materials included.
