Convert IGS to FBX Online
Convert IGS to FBX in seconds. IGS (IGES) is the 3-letter extension for the IGES CAD standard; 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 IGS to FBX?
The short version: IGS (IGES) is optimized for exchanging exact surface/curve geometry between legacy CAD systems, FBX is optimized for moving textured, rigged, animated assets between DCC tools and game engines, and this converter exists for the moment those two needs don't line up.
Our engine reads a file built around exchanging exact surface/curve geometry between legacy CAD systems and rebuilds it aiming to preserve this: the long-standing default asset format across game-engine pipelines — rather than producing a generic, lowest-common-denominator result.
FBX is Autodesk's game and animation interchange format, built around moving textured, rigged, animated assets between DCC tools and game engines. Converting from IGS (IGES) — built around exchanging exact surface/curve geometry between legacy CAD systems instead — closes that gap.
How to Convert IGS to FBX
- Upload your IGS 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
- Free for files up to 50MB, 100MB for registered accounts
- Converts IGS into FBX, aiming to preserve what matters most: the long-standing default asset format across game-engine pipelines
- Understands that IGS is the 3-letter extension for the IGES CAD standard and FBX is Autodesk's game and animation interchange format, rather than treating the conversion as a blind format swap
- Bridges the gap between IGS (IGES)'s focus on exchanging exact surface/curve geometry between legacy CAD systems and FBX's focus on moving textured, rigged, animated assets between DCC tools and game engines
- Keeps the parts of your file that matter for moving textured, rigged, animated assets between DCC tools and game engines intact, even though the source was built for exchanging exact surface/curve geometry between legacy CAD systems

Frequently Asked Questions
Why does FBX exist as a separate format instead of everyone just using IGS?
Because they're built for different jobs — IGS (IGES) is aimed at exchanging exact surface/curve geometry between legacy CAD systems, while FBX is aimed at moving textured, rigged, animated assets between DCC tools and game engines. Neither format is "better," they just fit different parts of a workflow.
Is this conversion free?
Yes — free for files up to 50MB, with a 100MB limit for registered accounts, no subscription required.
Do I need any special settings before uploading my IGS file?
No special setup is required — upload the file as-is. IGS (IGES) files meant for exchanging exact surface/curve geometry between legacy CAD systems convert most predictably; unusually exported or non-standard files are the most common reason a specific one might need extra attention.
Can I convert the file back from FBX to IGS afterward?
Only what FBX 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.
How long does the conversion take?
Most conversions finish in 10-30 seconds. Larger or more complex files can take up to a minute.
