Convert glTF to OBJ
Convert glTF files to OBJ in your browser. Free, no upload, no sign-up.
Convert glTF files to OBJ directly in your browser. The converter parses the glTF mesh, rebuilds it in memory and writes it out as OBJ, triangle for triangle. OBJ records shape and nothing else, so the colors and the unit definition in the glTF file do not come across. glTF measures in metres and OBJ in millimetres, so the numbers are rescaled rather than copied across. 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 glTF to OBJ
- 1Drop your glTF file
Drag a .gltf file onto the box above or click to choose one. Only self-contained .gltf files (embedded buffers) can be imported here, because external .bin and texture files cannot be resolved in the browser.
- 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 are glTF files?
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.

What are OBJ files?
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
