Convert FCSTD to GLB Online
Convert FCSTD to GLB in seconds. FreeCAD (FCStd) is FreeCAD's native parametric project format; GLB's strength is this: a single efficient file bundling geometry, materials, and textures. No software installation required — everything runs in your browser.

Why Convert FCSTD to GLB?
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. GLB doesn't share that problem — its strength: a single efficient file bundling geometry, materials, and textures.
If you need a file built for fast-loading real-time delivery for web and AR viewers but only have one built for open-source parametric CAD design with a full feature history, converting is usually the fastest path — FreeCAD (FCStd) and GLB serve different enough purposes that recreating the asset from scratch rarely makes sense.
Our engine reads a file built around open-source parametric CAD design with a full feature history and rebuilds it aiming to preserve this: a single efficient file bundling geometry, materials, and textures — rather than producing a generic, lowest-common-denominator result.
How to Convert FCSTD to GLB
- Upload your FCSTD file.
- MiConvert converts it to GLB, aiming to preserve what makes GLB useful: a single efficient file bundling geometry, materials, and textures.
- Download the converted GLB file.
- Use it directly with Three.js, Babylon.js, iOS/Android AR viewers.
Key Conversion Features
- Free for files up to 50MB, 100MB for registered accounts
- Fast turnaround, typically under a minute per file
- Bridges the gap between FreeCAD (FCStd)'s focus on open-source parametric CAD design with a full feature history and GLB's focus on fast-loading real-time delivery for web and AR viewers
- Converts FCSTD into GLB, aiming to preserve what matters most: a single efficient file bundling geometry, materials, and textures
- Purpose-built for the shift from open-source parametric CAD design with a full feature history to fast-loading real-time delivery for web and AR viewers, not a generic pass-through

Frequently Asked Questions
How long does the conversion take?
Most conversions finish in 10-30 seconds. Larger or more complex files can take up to a minute.
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, iOS/Android AR viewers either unless you plan to open or edit the GLB result afterward.
Why does GLB 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 GLB is aimed at fast-loading real-time delivery for web and AR viewers. Neither format is "better," they just fit different parts of a workflow.
What's the real difference between FCSTD and GLB?
FreeCAD (FCStd) is built around open-source parametric CAD design with a full feature history (FreeCAD's native parametric project format). GLB is built around fast-loading real-time delivery for web and AR viewers instead (the compact binary form of glTF) — different enough that this is a genuine format conversion, not just a rename.
