How to convert FBX to GLB

When to choose this format

GLB is convenient for sharing supported scene data in one file. For web use, also evaluate asset size: changing format is not a substitute for optimization.

How to convert

1. Install Fast Converter and Blender. Select the installed Blender folder in the Blender field.
2. Select FBX input and add your files with their linked resources available.
3. Choose GLB output. Open export settings and enable the options you need.
4. Choose a separate output folder and click Convert. Open the result in the destination application after processing.

Export settings

Choose FBX input, GLB output and an export folder. Enable Animation and Skeleton when needed. Make sure Blender can access the source images before conversion.

What to keep in mind

FBX materials may not map directly to glTF PBR materials. Complex shaders and rig details are not guaranteed to survive; the destination viewer’s lighting also affects appearance.

Check the result

Open GLB in the target viewer, preferably from another folder. Check textures, transparency, size and motion. For a heavy file, simplify geometry and reduce textures in an editor.

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.
