KPDFUtil is an application from Kevin Wells that provides a front-end to the facilities found in PDFUtils, itself a set of command line utilities for getting information about PDF documents, and performing actions on them such as extracting individual pages, converting them to HTML, and so on.
Kevin’s application presents a main window with the various possible actions in a series of buttons, and version 1.06 adds a menu over the main window as another method of accessing those actions.
If you find any of Kevin’s software, why not consider rewarding him for it by buying some merchandise or with a small contribution.
