Adobe Acrobat, the de facto PDF software, is an expensive utility when you only occasionally need to alter PDF documents. But when you need to, it is nice to have something readily available that works and works well. Even with Office 2013 gaining the ability to edit PDFs, there is still a place for the utilities that make manipulating PDFs easy. PDFMate Free PDF Merger is one of those free tools that can help you alter a PDF to be what you need. In addition, PDFMate PDF Converter allows you to convert PDF to various formats.
