Convert CSG to GLTF Online
Convert CSG to GLTF in seconds. CSG is a programmatic, boolean-built solid-geometry 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 CSG to GLTF?
CSG is a programmatic, boolean-built solid-geometry format, commonly used for parametric modeling built from combining primitive shapes. That focus comes with a real limitation: describes a construction script rather than explicit mesh geometry. glTF doesn't share that problem — its strength: an open, widely-adopted standard for real-time 3D delivery.
CSG is typically produced by or used with OpenSCAD and similar programmatic modelers, for parametric modeling built from combining primitive shapes. 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.
The short version: CSG is optimized for parametric modeling built from combining primitive shapes, glTF is optimized for human-readable, inspectable real-time 3D scene description, and this converter exists for the moment those two needs don't line up.
How to Convert CSG to GLTF
- Upload your CSG 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
- Understands that CSG is a programmatic, boolean-built solid-geometry format and GLTF is the JSON-based "JPEG of 3D", rather than treating the conversion as a blind format swap
- Built to handle the real-world quirks of files meant for parametric modeling built from combining primitive shapes, not just a textbook version of the format
- Purpose-built for the shift from parametric modeling built from combining primitive shapes to human-readable, inspectable real-time 3D scene description, not a generic pass-through
- Keeps the parts of your file that matter for human-readable, inspectable real-time 3D scene description intact, even though the source was built for parametric modeling built from combining primitive shapes
- Bridges the gap between CSG's focus on parametric modeling built from combining primitive shapes and glTF's focus on human-readable, inspectable real-time 3D scene description

Frequently Asked Questions
What happens to features specific to CSG that GLTF doesn't have?
CSG's real strength — captures a model as an editable, reproducible set of boolean operations — has no equivalent once converted, since glTF's constraint is: splits geometry, materials, and textures across separate files.
Is the conversion from CSG to GLTF reliable?
Straightforward files convert reliably. CSG's limitation — describes a construction script rather than explicit mesh geometry — combined with glTF expecting human-readable, inspectable real-time 3D scene description, means unusual or edge-case source files can occasionally need a second look.
Will I lose anything converting CSG to GLTF?
Converting to glTF means adapting to a real constraint: splits geometry, materials, and textures across separate files. Anything CSG carries — built as it is for parametric modeling built from combining primitive shapes — that has no equivalent there won't make the trip, but the core content converts faithfully.
Is GLTF objectively better than CSG?
Not objectively — glTF is better specifically for human-readable, inspectable real-time 3D scene description. For parametric modeling built from combining primitive shapes, CSG is still the right tool; that's exactly why both formats exist.
Is there a file size limit for this conversion?
Free conversions handle files up to 50MB; registered accounts get up to 100MB.
