Reezaa has debuted PDF Merger Mac 1.0, a free Mac OS X utility that allows users to merge multiple PDF files into a single file. You can select multiple PDF documents and, with the click of a single button, efficiently save them into a single document.

The final result retains the formatting, page size, and page orientation of the original files. The sequence of the source PDFs can be modified via the app’s Up and Down buttons.

PDF Merger Mac requires Mac OS X 10.8 or later. It’s available exclusively through the PDF Merger Mac website (http://www.pdfmergermac.com/).
