About This Tool

This online tool converts STL (Stereolithography) files to IGES (Initial Graphics Exchange Specification) format, enabling interoperability between different CAD systems. STL files represent 3D surfaces using triangular meshes, while IGES is a standard for exchanging CAD data with precise geometry representation. The converter processes both binary and ASCII STL files, extracts the 3D mesh data, and generates a valid IGES file with proper entity definitions. No software installation or registration is required - simply upload your STL file and download the converted IGES file instantly.
