Convert FBX to GLB from the right-click menu
Select an FBX model, hold Shift, right-click and pick 3D model, then GLB. Flecto converts it on your PC and saves the GLB, with its textures packed inside, in a new folder beside the original.

How to convert FBX to GLB with Flecto
- Select your FBX fileClick it in File Explorer.
- Hold Shift and right-clickChoose 3D model in the dial.
- Pick GLBThe other choices are OBJ, FBX, STL, GLB, glTF, DAE, USD, USDA and USDC.
- Open the new folderThe result and any companion files are saved in a new folder beside the original. Keep the folder together.
Good to know
- Static geometry and basic textured materials convert well. Complex shaders, rigs and animation can change in the conversion, so check the result.
- GLB is a single file with the textures inside. Pick glTF instead when you want the textures as separate image files.
- The engine is Blender 4.5 LTS. A compatible Blender 4.5 already on your PC can be reused.
- The first time, Flecto offers a one-time download of the 3D engine, about 399 MB. After that it works offline.
- The free plan includes 10 conversions every week. Failed or cancelled files do not count.
FBX and GLB
FBX is Autodesk’s exchange format, the usual export from Maya, 3ds Max and many asset stores. It is a closed format, and web browsers and lightweight viewers cannot read it.
GLB is the binary form of glTF, an open standard designed for fast loading. It is what three.js, model-viewer, Godot, most AR viewers and many online 3D galleries expect. Converting FBX to GLB is the usual last step before a model goes on a website.
Check these after converting
- Scale and orientation: FBX files do not all use the same units or up-axis.
- Materials: only standard colour, roughness, metal and normal textures carry across reliably.
- Textures: if the FBX pointed to image files that were missing, Flecto lists them in Conversion notes.txt beside the result.
Questions
Will animations convert?
Not always. Flecto is aimed at static models with basic textures. Rigs and animation can change or be lost.
What is the difference between GLB and glTF?
They hold the same data. GLB packs everything into one binary file; glTF is a text file with separate texture and data files.
Are my models uploaded?
No. They are converted on your PC. Only the optional 3D engine is downloaded, once.
Can I convert several files at once?
Yes. Select them together, then use the same Shift and right-click menu. The dial offers the formats they can all use.
