Desktop mesh in. One web file out.
Use this when you have an OBJ from a DCC or CAD dump and the destination is web or AR. The converter builds a GLB with a default material. It will not magically apply MTL, JPG, or PNG sidecars. If you needed the original paint, that work still lives in the DCC.
Source OBJ, target GLB, drop the .obj only, download a .glb.
1
Source is OBJ. The File API reads it in this tab. Nothing is posted. Keep it under 80 MB.
2
A GLB is packed with a default material around the OBJ mesh.
3
Preview in the GLB viewer. Convert OBJ to STL if you actually needed print.
This page is only OBJ → GLB. Other pairs have their own keep and lose notes so they do not repeat this conversion.
| On this conversion | What happens |
|---|---|
| Keeps | Geometry inside a GLB container. |
| Drops | MTL/texture lookdev. Export uses a default material. |
| Next step | Open the GLB viewer. For print, use OBJ to STL instead. |
| Attribute | Result on the reference scene |

| Vertex colour | Kept |
| Material names | Kept |
| Vertices on the reference scene | 48 of 48 |

OBJ as the source: Default material on export. Source has no PBR to keep. Measured 2026-08-27 by running this converter’s own loaders and exporters headlessly. How every format was measured.
OBJ is parsed with the File API. GLB is written in memory. MTL/texture lookdev. Export uses a default material. That is a format rule, not an upload. Files over 80 MB are refused because RAM is the limit.

Source OBJ, target GLB, drop the .obj only, download a .glb. No Blender and no account.
Not if the look lived in MTL and maps. This converter skips sidecars. You get a web-safe mesh with a default material.
GLB for web and AR. STL for a slicer. Do not use GLB as a print format.
No. OBJ is parsed here and GLB is written in memory. There is no convert API.
Yes. Open the OBJ viewer if you only need to orbit. Convert when the next tool actually wants GLB.
Open the GLB viewer. For print, use OBJ to STL instead.
