About the OBJ to GLB converter
A Wavefront OBJ ships as several loose files: the geometry, a .mtl material file and its textures. GLB packs all of that into one self-contained binary that modern engines and web viewers load directly, so converting an OBJ to GLB turns a fragile folder of files into a single portable model.
How to use the OBJ to GLB converter
- Drop the OBJ together with its .mtl and textures, or drop the whole folder.
- If a referenced .mtl is missing, add it so materials come through.
- Preview the converted model in 3D and set the scale if needed.
- Download a single GLB, or a zipped glTF.
Frequently asked questions
Drop the OBJ file along with its .mtl and textures, or drop the whole folder. The tool loads them, previews the model, and lets you download a single self-contained GLB or a glTF.
Only if you want materials and textures in the result. Without the .mtl the geometry still converts, but it comes through untextured, so include the .mtl and its images to keep the look.
GLB is one binary file with textures embedded, which is easiest to move around. The glTF option gives a .gltf with separate .bin and texture files, zipped, which is easier to edit.
No. The conversion runs entirely in your browser and nothing is uploaded.
