Convert BREP to FBX Online
Convert BREP to FBX in seconds. BREP is a raw boundary-representation CAD export; FBX's strength is this: the long-standing default asset format across game-engine pipelines. No software installation required — everything runs in your browser.

Why Convert BREP to FBX?
This conversion comes up whenever you need moving textured, rigged, animated assets between DCC tools and game engines instead of exchanging exact CAD surface geometry between engineering tools. BREP and FBX 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: the long-standing default asset format across game-engine pipelines.
FBX is Autodesk's game and animation interchange format, built around moving textured, rigged, animated assets between DCC tools and game engines. Converting from BREP — built around exchanging exact CAD surface geometry between engineering tools instead — closes that gap.
How to Convert BREP to FBX
- Upload your BREP file.
- MiConvert converts it to FBX, aiming to preserve what makes FBX useful: the long-standing default asset format across game-engine pipelines.
- Download the converted FBX file.
- Use it directly with Maya, 3ds Max, Unity, Unreal Engine.
Key Conversion Features
- Understands that BREP is a raw boundary-representation CAD export and FBX is Autodesk's game and animation interchange format, rather than treating the conversion as a blind format swap
- Purpose-built for the shift from exchanging exact CAD surface geometry between engineering tools to moving textured, rigged, animated assets between DCC tools and game engines, not a generic pass-through
- No local software installation required for either side — not CAD kernels like OpenCascade, not Maya, 3ds Max, Unity, Unreal Engine — everything runs in the cloud
- Bridges the gap between BREP's focus on exchanging exact CAD surface geometry between engineering tools and FBX's focus on moving textured, rigged, animated assets between DCC tools and game engines
- 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

Frequently Asked Questions
Is FBX objectively better than BREP?
Not objectively — FBX is better specifically for moving textured, rigged, animated assets between DCC tools and game engines. For exchanging exact CAD surface geometry between engineering tools, BREP is still the right tool; that's exactly why both formats exist.
Do I need any special settings before uploading my BREP file?
No special setup is required — upload the file as-is. BREP files meant for exchanging exact CAD surface geometry between engineering tools convert most predictably; unusually exported or non-standard files are the most common reason a specific one might need extra attention.
Is the conversion from BREP to FBX reliable?
Straightforward files convert reliably. BREP's limitation — a lower-level format most non-CAD software has no importer for — combined with FBX expecting moving textured, rigged, animated assets between DCC tools and game engines, means unusual or edge-case source files can occasionally need a second look.
Is there a file size limit for this conversion?
Free conversions handle files up to 50MB; registered accounts get up to 100MB.
How long does the conversion take?
Most conversions finish in 10-30 seconds. Larger or more complex files can take up to a minute.
