The only hsf to jpeg conversion we know about, represent export of visualized HOOPS 3D graphics (.hsf files) as JPEG pictures, which is typically done for preview purposes and not a way to export 3D graphics.
What you need is a tool that can open .hsf files, something that may be very problematic nowadays. Except for HOOPS 3D, almost no software natively support HSF and special plugin is often required. Export is often facilitated through exchange formats.
