Convert IGES to STL Online
Convert IGES to STL in seconds. IGES is an older CAD surface and curve exchange standard; STL's strength is this: the most universally supported format across 3D-printing software. No software installation required — everything runs in your browser.

Why Convert IGES to STL?
The short version: IGES is optimized for exchanging exact surface/curve geometry between legacy CAD systems, STL is optimized for virtually every slicer and 3D-printing workflow, and this converter exists for the moment those two needs don't line up.
IGES works well for exchanging exact surface/curve geometry between legacy CAD systems, but has a real limitation: represents a model as separate trimmed surface patches, not a unified solid. Converting trades that for this: the most universally supported format across 3D-printing software.
This conversion comes up whenever you need virtually every slicer and 3D-printing workflow instead of exchanging exact surface/curve geometry between legacy CAD systems. IGES and STL serve genuinely different purposes, so moving between them isn't just a formality.
How conversion works
- Upload your IGES file.
- MiConvert converts it to STL, aiming to preserve what makes STL useful: the most universally supported format across 3D-printing software.
- Download the converted STL file.
- Use it directly with every major slicer.
Key Conversion Features
- Understands that IGES is an older CAD surface and curve exchange standard and STL is the standard triangulated mesh format for 3D printing, rather than treating the conversion as a blind format swap
- Produces output ready for every major slicer, picking up right where most CAD systems left off
- Free for files up to 50MB, 100MB for registered accounts
- Purpose-built for the shift from exchanging exact surface/curve geometry between legacy CAD systems to virtually every slicer and 3D-printing workflow, not a generic pass-through
- Bridges the gap between IGES's focus on exchanging exact surface/curve geometry between legacy CAD systems and STL's focus on virtually every slicer and 3D-printing workflow

Frequently Asked Questions
What software works with the converted STL file?
STL is used by every major slicer. If you were working with most CAD systems (which produces IGES), this conversion is the direct bridge between the two.
Is this conversion free?
Yes — free for files up to 50MB, with a 100MB limit for registered accounts, no subscription required.
Is there a file size limit for this conversion?
Free conversions handle files up to 50MB; registered accounts get up to 100MB.
Will I lose anything converting IGES to STL?
Converting to STL means adapting to a real constraint: no color, material, or multi-object metadata. Anything IGES carries — built as it is for exchanging exact surface/curve geometry between legacy CAD systems — that has no equivalent there won't make the trip, but the core content converts faithfully.
Why does STL exist as a separate format instead of everyone just using IGES?
Because they're built for different jobs — IGES is aimed at exchanging exact surface/curve geometry between legacy CAD systems, while STL is aimed at virtually every slicer and 3D-printing workflow. Neither format is "better," they just fit different parts of a workflow.
