"Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch."

IRIS to STL Conversion: FAQ

What are IRIS files?

IRIS is an obsolete file format associated with workstations built by Silicon Graphics in the 1980s. Other similar formats, also known as RGB image formats, are SGI, RGB or RGBA. Unlike these extensions, IRIS is currently considered rare and might be difficult to open. For best results, we recommend converting it to a more accessible format.

What are STL files?

STL is the proprietary format for a computer-aided design (CAD) program developed by 3D Systems. STL is an acronym for Stereolitography, which is a type of technology used for creating prototypes or patterns through 3D printing. An STL file contains a surface representation of such a model, without detailed specifications of aspects such as colours. STL files can only be opened with a limited number of programs.
