Convert IGES to OBJ Online
Convert IGES to OBJ in seconds. IGES is an older CAD surface and curve exchange 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 IGES to OBJ?
IGES is typically produced by or used with most CAD systems, for exchanging exact surface/curve geometry between legacy CAD systems. 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.
Our engine reads a file built around exchanging exact surface/curve geometry between legacy CAD systems 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.
The short version: IGES is optimized for exchanging exact surface/curve geometry between legacy CAD systems, 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.
How conversion works
- Upload your IGES 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
- Bridges the gap between 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
- Fast turnaround, typically under a minute per file
- No local software installation required for either side — not most CAD systems, not virtually every 3D and rendering application — everything runs in the cloud
- 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
- 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 exchanging exact surface/curve geometry between legacy CAD systems

Frequently Asked Questions
Is this conversion free?
Yes — free for files up to 50MB, with a 100MB limit for registered accounts, no subscription required.
How long does the conversion take?
Most conversions finish in 10-30 seconds. Larger or more complex files can take up to a minute.
What's the real difference between IGES and OBJ?
IGES is built around exchanging exact surface/curve geometry between legacy CAD systems (an older CAD surface and curve exchange standard). OBJ is built around broad, simple mesh exchange across nearly every 3D application instead (the Wavefront geometry-plus-material format) — different enough that this is a genuine format conversion, not just a rename.
Is there a file size limit for this conversion?
Free conversions handle files up to 50MB; registered accounts get up to 100MB.
Can I convert the file back from OBJ to IGES afterward?
Only what OBJ actually carries can come back — anything specific to IGES's role in exchanging exact surface/curve geometry between legacy CAD systems that didn't survive the original conversion won't reappear.
