Convert FCSTD to GLTF Online
Convert FCSTD to GLTF in seconds. FreeCAD (FCStd) is FreeCAD's native parametric project format; glTF's strength is this: an open, widely-adopted standard for real-time 3D delivery. No software installation required — everything runs in your browser.

Why Convert FCSTD to GLTF?
FreeCAD (FCStd) is FreeCAD's native parametric project format, commonly used for open-source parametric CAD design with a full feature history. That focus comes with a real limitation: only FreeCAD reliably opens the parametric feature tree directly. glTF doesn't share that problem — its strength: an open, widely-adopted standard for real-time 3D delivery.
glTF is the JSON-based "JPEG of 3D", built around human-readable, inspectable real-time 3D scene description. Converting from FreeCAD (FCStd) — built around open-source parametric CAD design with a full feature history instead — closes that gap.
FreeCAD (FCStd) is typically produced by or used with FreeCAD, for open-source parametric CAD design with a full feature history. glTF is expected by Three.js, Babylon.js, and most modern web 3D viewers instead, for human-readable, inspectable real-time 3D scene description — converting bridges that gap.
How to Convert FCSTD to GLTF
- Upload your FCSTD file.
- MiConvert converts it to GLTF, aiming to preserve what makes glTF useful: an open, widely-adopted standard for real-time 3D delivery.
- Download the converted GLTF file.
- Use it directly with Three.js, Babylon.js, and most modern web 3D viewers.
Key Conversion Features
- Built to handle the real-world quirks of files meant for open-source parametric CAD design with a full feature history, not just a textbook version of the format
- Bridges the gap between FreeCAD (FCStd)'s focus on open-source parametric CAD design with a full feature history and glTF's focus on human-readable, inspectable real-time 3D scene description
- Produces output ready for Three.js, Babylon.js, and most modern web 3D viewers, picking up right where FreeCAD left off
- No local software installation required for either side — not FreeCAD, not Three.js, Babylon.js, and most modern web 3D viewers — everything runs in the cloud
- Understands that FCSTD is FreeCAD's native parametric project format and GLTF is the JSON-based "JPEG of 3D", rather than treating the conversion as a blind format swap

Frequently Asked Questions
Is GLTF objectively better than FCSTD?
Not objectively — glTF is better specifically for human-readable, inspectable real-time 3D scene description. For open-source parametric CAD design with a full feature history, FreeCAD (FCStd) is still the right tool; that's exactly why both formats exist.
Is this conversion free?
Yes — free for files up to 50MB, with a 100MB limit for registered accounts, no subscription required.
Do I need FreeCAD installed to convert my file?
No — the conversion happens entirely on our servers. You don't need FreeCAD, and you don't need Three.js, Babylon.js, and most modern web 3D viewers either unless you plan to open or edit the glTF result afterward.
Is there a file size limit for this conversion?
Free conversions handle files up to 50MB; registered accounts get up to 100MB.
Why does GLTF exist as a separate format instead of everyone just using FCSTD?
Because they're built for different jobs — FreeCAD (FCStd) is aimed at open-source parametric CAD design with a full feature history, while glTF is aimed at human-readable, inspectable real-time 3D scene description. Neither format is "better," they just fit different parts of a workflow.
