How to convert GLB to OBJ

  1. Drop a GLB, or a glTF with its .bin and texture files. It's read on your device, not uploaded.
  2. Choose who the OBJ is for. Blender keeps the model upright in metres, as glTF stores it. Slicer or CAD stands it on Z and converts to millimetres for printing.
  3. Download. When the model has colours, you get the OBJ and its MTL material file together in a zip, so other 3D apps show them.

What carries over

  • Kept: every mesh, as a named object, and each part's base colour.
  • Not kept: image textures, animation and rigging. OBJ stores colour per material, not painted textures; the 3D view shows the textures, the download keeps base colours.
  • Animated models are exported in the pose shown: pause the animation on the frame you want first.

Models from AI generators

Meshy, Tripo and other AI generators usually hand out GLB. For a 3D app, OBJ is fine. To print the model, go straight to GLB to STL, which sizes it in millimetres and checks it is watertight, then repair it if needed.

Questions

How do I convert GLB to OBJ for free?

Drop the GLB into the tool on this page and click Download OBJ. It's free, needs no sign-up, and nothing is uploaded.

Does the OBJ keep the textures?

It keeps each part's base colour in an MTL file. Image textures and animations don't carry over to the OBJ.

Why is my GLB tiny or huge after converting?

glTF is in metres. Pick Blender to keep metres, or Slicer or CAD to convert to millimetres for printing; you can also set the size before downloading.

Can I open AI-generated models from Meshy or Tripo?

Yes. They're ordinary GLB files. For printing, GLB to STL is the better route: it sizes the model in mm and checks it is watertight.
