How to convert OBJ to GLB
- Add your .OBJ file - drop it in the box above or click to browse.
- Convert it to .GLB in a few seconds.
- Download your new .GLB file.
What to expect
- Mesh geometry transfers directly at the same polygon resolution.
- glTF stores geometry in binary buffers, generally more compact than OBJ's plain-text coordinates.
- Material and color from the OBJ's MTL may map into glTF materials, but detailed texture mapping does not always survive the conversion.
Frequently asked questions
How well does the geometry transfer from OBJ to GLB?
Both OBJ and GLB describe polygon meshes, so the geometry transfers directly and the shape is preserved at the same mesh resolution.
Why convert OBJ to GLB?
GLB is the glTF 2.0 binary format, the standard for 3D on the web and in AR and real-time viewers. Converting packages an OBJ into one self-contained file suited to those uses.
Where does a GLB file open?
GLB opens in Microsoft 3D Viewer on Windows, Quick Look on macOS and browser-based glTF viewers. Unlike OBJ, a single GLB bundles geometry, materials and textures together.
Is a GLB larger or smaller than the OBJ?
GLB stores geometry as binary rather than OBJ's plain-text numbers, which is usually more compact, though embedding textures adds their size into the one file.
