PDF Simple Compression

A simple utility program for Windows that will help reduce the size of most PDFs.

There are numerous PDF compression utilities out there. Most seem to either cost a bit, but only work ok, or are free and do not work well. Online versions work great, but really only handle 1 file at a time. We are offering one that works well and is free, and can handle multiple source folders at one time. We are also offering the source for it for those interested in seeing how it works.

This utility uses the Ghostscript APIs, which is a vast library of free software that can manipulate PDFs and PostScript files. For more on ghostscript, visit http://ghostscript.com/


Current version: 1.2

For Windows 7, 8, 8.1, 10
