Convert GLB to OBJ
Convert a GLB file to OBJ in your browser. Free, no upload, no sign-up.
Convert GLB files to OBJ directly in your browser. The converter parses the GLB mesh, rebuilds it in memory and writes it out as OBJ, keeping every triangle. Nothing is uploaded, there is no file size limit beyond your computer's memory, and the result downloads instantly. OBJ keeps groups and UV coordinates and opens in every modelling tool, which makes it a good format for editing or texturing a model.
How to convert GLB to OBJ
- 1Drop your GLB file
Drag a .glb file onto the box above or click to choose one.
- 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 OBJ
Adjust the export options if needed and click download. A .mtl material file is not generated; the exported OBJ contains geometry, normals and UVs only.
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
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
OBJ keeps groups and UV coordinates and opens in every modelling tool, which makes it a good format for editing or texturing a model.
