Convert FBX to GLB
Convert FBX to GLB in your browser. The conversion runs on this page and the file never leaves your computer.
Result
Before you convert: what this keeps and what it destroys
Preserved
- The geometry, triangle for triangle
- Overall dimensions and proportions
- Watertightness, where the input is watertight
- Colour
- Separate parts and their positions
Destroyed
- A recorded unit: GLB stores none
Why people convert FBX to GLB
This is the modernisation people reach for: the same scene model, an open specification, and far better support outside Autodesk's own tools.
One thing to settle first. Most people converting FBX to GLB want the animation to come with it, and this site does not carry animation. It reads geometry, the node transforms and material colour. Rigs, skinning weights and animation curves are not read at all. If the rig is the reason you are here, use Blender or Facebook's FBX2glTF, which exist for exactly that job.
For the geometry itself this is a good target, and better than any other mesh format on this site. GLB keeps a real node hierarchy, so a multi-part model arrives as separate, correctly positioned parts instead of one merged body. Material colour survives as a PBR base colour.
FBX records a unit scale factor in centimetres per file unit and glTF is metres, so the coordinates are rescaled. Check the overall size, because a surprising scale factor in the source is common and this conversion faithfully carries it through.
What you get
You get a binary GLB file containing the same triangles the FBX file described. No geometry is added, removed or approximated: mesh-to-mesh conversion is a change of container, and this site's tests check that the triangle count comes out identical.
The output uses metres, as required by the glTF specification.
Carried across: supported base or vertex colour, the supported part structure.
The conversion runs in your browser. Your file stays on your computer and is not uploaded.
What to check afterwards
- FBX declares its unit in the file. Check the output dimensions in the receiving application, especially when its import settings can override the unit.
- Coordinates are stored as 32-bit floats. For a part measured in millimetres that's far finer than any machine tolerance. For a model spanning hundreds of thousands of units it isn't.
If you need something this conversion cannot give you
This pair loses very little. GLB carries what FBX carries, so the main reason to choose a different target is what the receiving software accepts.
Going the other way
This site reads FBX but does not write it. For the reverse conversion, use an application that can export FBX.
How we know this conversion works
This pair was checked against 2 files from the test corpus on 2026-09-04. Each run parses its own output back in and compares the bounding box, the triangle count and, for closed solids, the volume against the input.
A pair that fails those checks doesn't get a page. That's why this site lists 120 conversions and not the several hundred a format-times-format grid would suggest.
