GLB to OBJ
Convert a GLB or glTF model to OBJ, which older modelling software reads.
What it does
GLB to OBJ rewrites the model into another container. The vertices, faces and normals are carried across unchanged — this is a re-encode of the same geometry, not a re-modelling of it, so the shape you get out is the shape you put in.
When you need it
Almost always because the next piece of software only reads one format: a slicer that wants STL, a browser or AR viewer that wants GLB, an older 3D application that only ever learned OBJ.
Limits and caveats
What each format can carry differs, and that is where things go missing: STL holds geometry only, so colours and materials do not survive it, and OBJ keeps materials in a separate .mtl that a dropped file does not include. Geometry always survives; appearance often does not. Everything happens in your browser, so the file never leaves your device.
How to glb to obj
- Drop or choose your GLB file.
- KIVO processes it instantly — no waiting for uploads.
- Download the result. That's it.
Frequently asked questions
- Do the materials survive?
- No. The geometry converts; the materials do not travel without the companion .mtl file this tool doesn't write.
- Do my files get uploaded?
- No. This tool runs entirely in your browser, so the file never leaves your device.
