Webify:

Webify is a program which makes web-browsable trees of hypertext files and JEPG images from Postscript source files.

Webify is freely distributed in C source form, and runs on UNIX systems having Ghostscript installed with PPMRAW conversion along with the cjpeg or ppmtogif utilities (all available free). It can be used (on UNIX systems) to convert postscript files generated on Macs, PCs, and elsewhere.
