If you work with pdf files, PDFGenius is a must have application. It does all kinds of useful things — merge multiple pdf files, remove unwanted pages in a pdf file, split up a file, rotate pages so you don’t have to twist your head to read vertical pages, and much more. The support is also excellent. I got some pdf files that had some king of format error in them which prevented merging. I sent two files to support and they identified the problem and gave me a simple solution — just input the bad file and do a save as. PDFGenius corrects the error in its output file so merging works fine.
