Converting an OBJ. model to a GLB. model, using Blender

Here you will learn how to quickly convert an .obj model to a .glb model using Blender - including setting scale and rotation.

Step 1: Install Blender 


If you haven't installed Blender, download and install it from the official website: ( 


Step 2: Open Blender 


Launch Blender and you'll see the default scene. 


Step 3: Import OBJ File 


  1. Delete Default Objects:

    Select the default cube, light, and camera objects and press `Delete` on your keyboard to remove them. 

  2. Import OBJ File:

   - Go to `File > Import > Wavefront (.obj)`. 

   - Navigate to your OBJ file and select it. 


Step 4: Set Scaling 


  1. Check Object Size:

   - After importing, your object might be too large or too small. 

   - Hold the mouse at the main 3D view (mouse location affects which menu is opened)  

   - Press `N` to open the right-hand toolbar and go to the "Item" tab. 

  1. Adjust Scale:

   - Look for the "Scale" section. 

   - Set the scale values to make the object the desired size. A common scale might be `0.01` for reducing size. 


Step 5: Set Rotation 


  1. Check Object Rotation:

   - Ensure your object is oriented correctly. If it's not facing the right direction, you'll need to adjust the rotation. 


  1. Rotate Object:

    - Press `N` to open the right-hand toolbar and go to the "Item" tab. 

   - Type in a value at the "Rotation" section to rotate the object until it faces the desired direction. 


Step 6: Apply Scale & Rotation 

   - Select all of the objects. 

   - Navigate to the Object menu -> Apply -> Rotation & Scale to apply the values you have currently set to the object.  


Step 7: Export as GLB 


  1. Delete Unnecessary Elements:

   - Remove any unnecessary elements or objects in your scene. 


  1. Export as GLB:

   - Go to `File > Export > glTF 2.0 (.glb)`. 

   - Choose a destination and name for your GLB file. 

   - In the export settings, ensure "Selected Objects" is checked if you only want to export the currently selected object. 

   - Click on "Export glTF 2.0" to save your GLB file. 


Step 8: Check Your GLB File 


To ensure that everything worked correctly, you can use a 3D viewer or an online GLB viewer to open and inspect your GLB file like (files are stored locally on your PC, the browser link is just a viewer nothing is uploaded to the website).  


That's it! You've successfully converted an OBJ file to a GLB model in Blender, including setting the scaling and rotation.
