Convert IGS to OBJ Online
Convert IGS to OBJ in seconds. IGS (IGES) is the 3-letter extension for the IGES CAD standard; 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 IGS to OBJ?
If you need a file built for broad, simple mesh exchange across nearly every 3D application but only have one built for exchanging exact surface/curve geometry between legacy CAD systems, converting is usually the fastest path — IGS (IGES) and OBJ serve different enough purposes that recreating the asset from scratch rarely makes sense.
IGS (IGES) is the 3-letter extension for the IGES CAD standard, commonly used for exchanging exact surface/curve geometry between legacy CAD systems. That focus comes with a real limitation: represents a model as separate trimmed surface patches, not a unified solid. OBJ doesn't share that problem — its strength: one of the most universally supported 3D formats in existence.
OBJ was built around broad, simple mesh exchange across nearly every 3D application, which is precisely the gap IGS (IGES) leaves open, since it's designed around exchanging exact surface/curve geometry between legacy CAD systems instead.
How to Convert IGS to OBJ
- Upload your IGS 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
- Fast turnaround, typically under a minute per file
- Purpose-built for the shift from exchanging exact surface/curve geometry between legacy CAD systems to broad, simple mesh exchange across nearly every 3D application, not a generic pass-through
- No local software installation required for either side — not most CAD systems, not virtually every 3D and rendering application — everything runs in the cloud
- Bridges the gap between IGS (IGES)'s focus on exchanging exact surface/curve geometry between legacy CAD systems and OBJ's focus on broad, simple mesh exchange across nearly every 3D application
- Converts IGS into OBJ, aiming to preserve what matters most: one of the most universally supported 3D formats in existence

Frequently Asked Questions
What software works with the converted OBJ file?
OBJ is used by virtually every 3D and rendering application. If you were working with most CAD systems (which produces IGS (IGES)), this conversion is the direct bridge between the two.
Can I convert the file back from OBJ to IGS afterward?
Only what OBJ actually carries can come back — anything specific to IGS (IGES)'s role in exchanging exact surface/curve geometry between legacy CAD systems that didn't survive the original conversion won't reappear.
What happens to features specific to IGS that OBJ doesn't have?
IGS (IGES)'s real strength — still widely supported across older and current CAD software alike — 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.
Why would I need OBJ instead of just keeping IGS?
Mainly when your workflow specifically calls for broad, simple mesh exchange across nearly every 3D application — that's OBJ's whole reason for existing, and IGS (IGES) isn't built to provide it, since it's focused on exchanging exact surface/curve geometry between legacy CAD systems instead.
