How to convert GLB to OBJ
Extract a static model from GLB into OBJ for editing. The output may contain a model, material description and images instead of a single container.

When to choose this format
This workflow suits static props and environments when the receiving program accepts OBJ but not binary glTF.
How to convert
- Install Fast Converter and Blender. Select the installed Blender folder in the Blender field.
- Select GLB input and add your files with their linked resources available.
- Choose OBJ output. Open export settings and enable the options you need.
- Choose a separate output folder and click Convert. Open the result in the destination application after processing.
Export settings
Add the GLB, choose OBJ and a separate output folder. Enable textures for textured assets. Share the entire export folder rather than only the .obj file.
What to keep in mind
OBJ does not retain a skeleton or motion. glTF metallic and roughness properties may look different in MTL materials. Conversion does not automatically reduce polygon count.
Check the result
Compare silhouette, UVs, normals and scale. If the model is gray, inspect the MTL and confirm its referenced images are present with the output.
Available in the free version
Process multiple models of one input format and choose one output format per run. Free input formats: GLB, GLTF, FBX, OBJ and BLEND. Free outputs: FBX, OBJ, DAE, GLB, GLTF and BLEND. Mixed inputs, multiple outputs, advanced formats, model preview, LOD removal and ungrouping require Premium.
Common questions
Do I upload my model to the website?
No. Install the Windows application: conversion runs on your computer using Blender. The website provides an interactive interface demonstration.
Can I convert multiple files for free?
Yes: add multiple models of one supported input format and choose one supported output format. Mixed input batches and multiple output formats require Premium.

A gray or pink model does not necessarily mean its geometry was lost. Check the source images, their paths and the output format’s capabilities first.
