When saving a document from Microsoft Word 2007 or higher to PDF, there are two options, namely Standard (to be printed) and Minimum size so that the PDF size smaller. But what if we already have a PDF document and want to shrink in size without the need to first convert it to a word? One of the free software that can be used is ORPALIS PDF Reducer. There are 2 editions, and which I review is the free edition.
