Convert IGS to GLTF Online
Convert IGS to GLTF in seconds. IGS (IGES) is the 3-letter extension for the IGES CAD standard; 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 IGS to GLTF?
IGS (IGES)'s limitation: represents a model as separate trimmed surface patches, not a unified solid. glTF's strength: an open, widely-adopted standard for real-time 3D delivery — it doesn't share that constraint.
The short version: IGS (IGES) is optimized for exchanging exact surface/curve geometry between legacy CAD systems, 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.
Our engine reads a file built around exchanging exact surface/curve geometry between legacy CAD systems and rebuilds it aiming to preserve this: an open, widely-adopted standard for real-time 3D delivery — rather than producing a generic, lowest-common-denominator result.
How to Convert IGS to glTF
- Upload your IGS 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
- Free for files up to 50MB, 100MB for registered accounts
- Bridges the gap between IGS (IGES)'s focus on exchanging exact surface/curve geometry between legacy CAD systems 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 most CAD systems left off
- 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 exchanging exact surface/curve geometry between legacy CAD systems
- Purpose-built for the shift from exchanging exact surface/curve geometry between legacy CAD systems to human-readable, inspectable real-time 3D scene description, not a generic pass-through

Frequently Asked Questions
Is GLTF objectively better than IGS?
Not objectively — glTF is better specifically for human-readable, inspectable real-time 3D scene description. For exchanging exact surface/curve geometry between legacy CAD systems, IGS (IGES) 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.
Will I lose anything converting IGS to GLTF?
Converting to glTF means adapting to a real constraint: splits geometry, materials, and textures across separate files. Anything IGS (IGES) carries — built as it is for exchanging exact surface/curve geometry between legacy CAD systems — that has no equivalent there won't make the trip, but the core content converts faithfully.
What's the real difference between IGS and GLTF?
IGS (IGES) is built around exchanging exact surface/curve geometry between legacy CAD systems (the 3-letter extension for the IGES CAD standard). glTF is built around human-readable, inspectable real-time 3D scene description instead (the JSON-based "JPEG of 3D") — different enough that this is a genuine format conversion, not just a rename.
Is the conversion from IGS to GLTF reliable?
Straightforward files convert reliably. IGS (IGES)'s limitation — represents a model as separate trimmed surface patches, not a unified solid — 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.
