What is it? IGES to STL converts IGES CAD models into STL meshes ready for 3D printing or slicing, running entirely in the browser.

TL;DR: Convert IGES models to printable STL.

How to use

Are curved surfaces smooth?

Surfaces are tessellated; the default resolution is suitable for printing.

Is it private?

Yes, conversion happens locally.

Some IGES entity types may be approximated or skipped.
Large files are memory-bound.
Tessellation precision presets: Draft / Standard / High / Ultra.
IGES files commonly use inch units while STL is unitless - confirm the mm scale in your slicer.
Large models are memory-bound; keep IGES files under 100 MB.
