Convert OBJ to glTF
Convert a OBJ file to glTF in your browser. Free, no upload, no sign-up.
Convert OBJ files to glTF directly in your browser. The converter parses the OBJ mesh, rebuilds it in memory and writes it out as glTF, keeping every triangle. Nothing is uploaded, there is no file size limit beyond your computer's memory, and the result downloads instantly. glTF gives you a readable JSON scene that is easy to inspect, diff or post-process in a build pipeline.
How to convert OBJ to glTF
- 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 glTF
Adjust the export options if needed and click download. Buffers are embedded in the JSON as base64, so the output is a single file.
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

What is a glTF file?
glTF is the JSON form of the same Khronos standard as GLB. The .gltf file describes the scene as readable JSON; binary buffers and textures may be embedded as base64 or kept as separate files. It is convenient when you want to inspect or edit the scene description by hand.
Commonly used by: web developers, Babylon.js / three.js, Blender, Unity and Unreal importers
