Convert 3DM to OBJ Online
Convert 3DM to OBJ in seconds. 3DM (Rhino) is Rhino's native NURBS surface format; 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 3DM to OBJ?
The short version: 3DM (Rhino) is optimized for freeform industrial design, jewelry, and architectural modeling, OBJ is optimized for broad, simple mesh exchange across nearly every 3D application, and this converter exists for the moment those two needs don't line up.
3DM (Rhino) is typically produced by or used with Rhinoceros, for freeform industrial design, jewelry, and architectural modeling. OBJ is expected by virtually every 3D and rendering application instead, for broad, simple mesh exchange across nearly every 3D application — converting bridges that gap.
3DM (Rhino) is Rhino's native NURBS surface format, commonly used for freeform industrial design, jewelry, and architectural modeling. That focus comes with a real limitation: tied to Rhino's own file structure, which most other 3D software can't open directly. OBJ doesn't share that problem — its strength: one of the most universally supported 3D formats in existence.
How to Convert 3DM to OBJ
- Upload your 3DM 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
- No local software installation required for either side — not Rhinoceros, not virtually every 3D and rendering application — everything runs in the cloud
- Bridges the gap between 3DM (Rhino)'s focus on freeform industrial design, jewelry, and architectural modeling and OBJ's focus on broad, simple mesh exchange across nearly every 3D application
- Converts 3DM into OBJ, aiming to preserve what matters most: one of the most universally supported 3D formats in existence
- Free for files up to 50MB, 100MB for registered accounts
- Keeps the parts of your file that matter for broad, simple mesh exchange across nearly every 3D application intact, even though the source was built for freeform industrial design, jewelry, and architectural modeling

Frequently Asked Questions
Do I need Rhinoceros installed to convert my file?
No — the conversion happens entirely on our servers. You don't need Rhinoceros, and you don't need virtually every 3D and rendering application either unless you plan to open or edit the OBJ result afterward.
Do I need any special settings before uploading my 3DM file?
No special setup is required — upload the file as-is. 3DM (Rhino) files meant for freeform industrial design, jewelry, and architectural modeling convert most predictably; unusually exported or non-standard files are the most common reason a specific one might need extra attention.
What happens to features specific to 3DM that OBJ doesn't have?
3DM (Rhino)'s real strength — exact curved-surface precision for freeform shapes — has no equivalent once converted, since OBJ's constraint is: no animation, rigging, or scene hierarchy support.
How long does the conversion take?
Most conversions finish in 10-30 seconds. Larger or more complex files can take up to a minute.
Is the conversion from 3DM to OBJ reliable?
Straightforward files convert reliably. 3DM (Rhino)'s limitation — tied to Rhino's own file structure, which most other 3D software can't open directly — combined with OBJ expecting broad, simple mesh exchange across nearly every 3D application, means unusual or edge-case source files can occasionally need a second look.
