Convert BREP to GLTF Online
Convert BREP to GLTF in seconds. BREP is a raw boundary-representation CAD export; 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 BREP to GLTF?
This conversion comes up whenever you need human-readable, inspectable real-time 3D scene description instead of exchanging exact CAD surface geometry between engineering tools. BREP and glTF serve genuinely different purposes, so moving between them isn't just a formality.
BREP works well for exchanging exact CAD surface geometry between engineering tools, but has a real limitation: a lower-level format most non-CAD software has no importer for. Converting trades that for this: 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 BREP — built around exchanging exact CAD surface geometry between engineering tools instead — closes that gap.
How to Convert BREP to glTF
- Upload your BREP 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
- No local software installation required for either side — not CAD kernels like OpenCascade, not Three.js, Babylon.js, and most modern web 3D viewers — everything runs in the cloud
- Bridges the gap between BREP's focus on exchanging exact CAD surface geometry between engineering tools and glTF's focus on human-readable, inspectable real-time 3D scene description
- Built to handle the real-world quirks of files meant for exchanging exact CAD surface geometry between engineering tools, not just a textbook version of the format
- Fast turnaround, typically under a minute per file
- Produces output ready for Three.js, Babylon.js, and most modern web 3D viewers, picking up right where CAD kernels like OpenCascade left off

Frequently Asked Questions
What's the real difference between BREP and GLTF?
BREP is built around exchanging exact CAD surface geometry between engineering tools (a raw boundary-representation CAD export). 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.
How long does the conversion take?
Most conversions finish in 10-30 seconds. Larger or more complex files can take up to a minute.
What happens to features specific to BREP that GLTF doesn't have?
BREP's real strength — stores exact mathematical surfaces rather than an approximated mesh — has no equivalent once converted, since glTF's constraint is: splits geometry, materials, and textures across separate files.
Will I lose anything converting BREP to GLTF?
Converting to glTF means adapting to a real constraint: splits geometry, materials, and textures across separate files. Anything BREP carries — built as it is for exchanging exact CAD surface geometry between engineering tools — that has no equivalent there won't make the trip, but the core content converts faithfully.
Why does GLTF exist as a separate format instead of everyone just using BREP?
Because they're built for different jobs — BREP is aimed at exchanging exact CAD surface geometry between engineering tools, 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.
