Convert BREP to GLB Online
Convert BREP to GLB in seconds. BREP is a raw boundary-representation CAD export; 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 BREP to GLB?
Our engine reads a file built around exchanging exact CAD surface geometry between engineering tools 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.
GLB is the compact binary form of glTF, built around fast-loading real-time delivery for web and AR viewers. Converting from BREP — built around exchanging exact CAD surface geometry between engineering tools instead — closes that gap.
BREP is a raw boundary-representation CAD export, commonly used for exchanging exact CAD surface geometry between engineering tools. That focus comes with a real limitation: a lower-level format most non-CAD software has no importer for. GLB doesn't share that problem — its strength: a single efficient file bundling geometry, materials, and textures.
How to Convert BREP to GLB
- Upload your BREP 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
- Produces output ready for Three.js, Babylon.js, iOS/Android AR viewers, picking up right where CAD kernels like OpenCascade left off
- 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
- Bridges the gap between BREP's focus on exchanging exact CAD surface geometry between engineering tools and GLB's focus on fast-loading real-time delivery for web and AR viewers
- Understands that BREP is a raw boundary-representation CAD export and GLB is the compact binary form of glTF, rather than treating the conversion as a blind format swap
- No local software installation required for either side — not CAD kernels like OpenCascade, not Three.js, Babylon.js, iOS/Android AR viewers — everything runs in the cloud

Frequently Asked Questions
Is there a file size limit for this conversion?
Free conversions handle files up to 50MB; registered accounts get up to 100MB.
What's the real difference between BREP and GLB?
BREP is built around exchanging exact CAD surface geometry between engineering tools (a raw boundary-representation CAD export). 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.
Can I convert the file back from GLB to BREP afterward?
Only what GLB actually carries can come back — anything specific to BREP's role in exchanging exact CAD surface geometry between engineering tools that didn't survive the original conversion won't reappear.
Is the conversion from BREP to GLB reliable?
Straightforward files convert reliably. BREP's limitation — a lower-level format most non-CAD software has no importer for — combined with GLB expecting fast-loading real-time delivery for web and AR viewers, means unusual or edge-case source files can occasionally need a second look.
How long does the conversion take?
Most conversions finish in 10-30 seconds. Larger or more complex files can take up to a minute.
