The goal of this application is straightforward: it allows for changing of zoom level of links and bookmarks in PDF files. It does what commercial software is capable of but does it free of charge. It covers most of zoom levels (i.e. FitPage, FitH and so on) found in PDF files.
Run the application with three parameters, first pointing to source PDF file, second to resulting file, and third to the desired zoom level.
PdfZoomChanger.exe source.pdf destination.pdf 1.25
If a zoom level is omitted, the default value of 1.0 will be used instead.
