How to convert GLB to FBX
Convert a GLB model to FBX for a 3D editor or game project. Fast Converter processes files locally on Windows using your installed copy of Blender.

When to choose this format
GLB is convenient for sharing a glTF scene in a single file. FBX is useful when the next tool in your workflow expects FBX input. Check that tool’s material, scale and animation requirements before converting.
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 FBX 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
Enable Textures in export settings if the output needs them. For an animated model, enable Animation and, for a rigged model, Skeleton. These options do not guarantee that every material system or rig transfers unchanged.
What to keep in mind
glTF and FBX use different material representations. Procedural shaders, glTF extensions and complex scene relationships may need manual adjustments. After importing FBX, check transparency, normals, model size and animation playback.
Check the result
Open the FBX in the destination application. Compare its objects and appearance with the source; check several frames if it is animated. Keep the original GLB until you finish checking.
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.
A small verified example
We checked this workflow with a simple textured cube using the Fast Converter conversion script and Blender 4.0. This verifies a basic scenario; it does not guarantee compatibility with every model, material or rig.

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.
