Convert OBJ to GLB
Convert OBJ to GLB in your browser. The conversion runs on this page and the file never leaves your computer.
Result
Before you convert: what this keeps and what it destroys
Preserved
- The geometry, triangle for triangle
- Overall dimensions and proportions
- Watertightness, where the input is watertight
- Colour
- Separate parts and their positions
Destroyed
- A recorded unit: GLB stores none

Why people convert OBJ to GLB
You do this to put a downloaded mesh on the web, into a browser viewer, or into AR on an Android device, as one self-contained file.
Will the GLB include my OBJ textures?
This converter reads the OBJ you select. It does not load a separate .mtl file or the images that file references, so it cannot include those textures in the GLB. To keep the textured appearance, import the whole asset into an application that can export it.
Named OBJ parts can remain distinguishable in the output. That does not recover a parent-child hierarchy that was absent from the source OBJ.
Check the scale of a web model
The converter assumes the OBJ coordinates are millimetres and writes GLB geometry in metres. A 100 mm length becomes 0.1 metres. If the OBJ was authored with another unit convention, correct that interpretation before using the result at physical scale.
GLB to OBJ goes back to a mesh file. It does not reconstruct a CAD solid, and it cannot bring back materials that were missing on import.
The conversion runs in your browser. Your file stays on your computer and is not uploaded.
How we know this conversion works
This pair was checked against 3 files from the test corpus on 2026-09-04. Each run parses its own output back in and compares the bounding box, the triangle count and, for closed solids, the volume against the input.
A pair that fails those checks doesn't get a page. That's why this site lists 120 conversions and not the several hundred a format-times-format grid would suggest.
