Convert BREP to OBJ Online
Convert BREP to OBJ in seconds. BREP is a raw boundary-representation CAD export; OBJ's strength is this: one of the most universally supported 3D formats in existence. No software installation required — everything runs in your browser.

Why Convert BREP to OBJ?
OBJ is the Wavefront geometry-plus-material format, built around broad, simple mesh exchange across nearly every 3D application. Converting from BREP — built around exchanging exact CAD surface geometry between engineering tools instead — closes that gap.
Our engine reads a file built around exchanging exact CAD surface geometry between engineering tools and rebuilds it aiming to preserve this: one of the most universally supported 3D formats in existence — rather than producing a generic, lowest-common-denominator result.
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. OBJ doesn't share that problem — its strength: one of the most universally supported 3D formats in existence.
How to Convert BREP to OBJ
- Upload your BREP file.
- MiConvert converts it to OBJ, aiming to preserve what makes OBJ useful: one of the most universally supported 3D formats in existence.
- Download the converted OBJ file.
- Use it directly with virtually every 3D and rendering application.
Key Conversion Features
- Understands that BREP is a raw boundary-representation CAD export and OBJ is the Wavefront geometry-plus-material format, rather than treating the conversion as a blind format swap
- No local software installation required for either side — not CAD kernels like OpenCascade, not virtually every 3D and rendering application — everything runs in the cloud
- Purpose-built for the shift from exchanging exact CAD surface geometry between engineering tools to broad, simple mesh exchange across nearly every 3D application, not a generic pass-through
- 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
- Free for files up to 50MB, 100MB for registered accounts

Frequently Asked Questions
Will I lose anything converting BREP to OBJ?
Converting to OBJ means adapting to a real constraint: no animation, rigging, or scene hierarchy support. 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.
Is OBJ objectively better than BREP?
Not objectively — OBJ is better specifically for broad, simple mesh exchange across nearly every 3D application. For exchanging exact CAD surface geometry between engineering tools, BREP 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.
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.
How long does the conversion take?
Most conversions finish in 10-30 seconds. Larger or more complex files can take up to a minute.
