How to convert FBX to glTF
Before you start
Drop one or more FBX files; this format cannot be pasted as plain text.
Accepted: .fbx · application/octet-stream- Choose or drag one or more FBX files onto the drop zone.
- Confirm the detected format. Mixed-format batches are flagged before conversion.
- Select “Convert on this device.” Produces previewable glTF text and a correctly named download.
How this converter behaves
Geometry is parsed into an in-memory mesh, validated, and serialized into the destination model format. The page previews structure without running scripts from the model.
What happens to your data?
The conversion engine runs in this browser tab. OmniCastConverter has no upload API and never sends your content, file name, or converted result to a server.
Fidelity and limitations
This route is classified as structural. The converter preserves meaning and structure supported by both formats.
- The safe importer accepts ASCII FBX polygon geometry. Binary FBX requires conversion to ASCII FBX, GLB, or OBJ first.
- Geometry is triangulated; materials, textures, scene hierarchy, and animation are not preserved.
Try a valid example
The “Use example” action in the workbench loads this exact input. Produces previewable glTF text and a correctly named download.
