When thinking about PDF editors, Adobe Acrobat Reader is probably the one that comes to mind first. But that doesn't mean there aren't alternative tools that can do the job just as well – such as Nuance PDF Reader.
With Nuance PDF Reader you can easily open and read PDF files on your computer. This simple PDF editor loads in seconds (unlike Adobe's mammoth app) and has a nicely designed interface.
Nuance PDF Reader features the classic tools and options you'd expect to expect to find in any regular PDF reader: full screen view, support for zooming in and out, ability to display several pages on screen simultaneously, and utilities to select, underline and highlight text.
As extra features, Nuance PDF Reader lets you email any PDF file right from the program and also allows you to convert files from PDF to other formats (DOC, DOCX, XLS, RTF), though this must be done through Nuance's online converter. On the downside, the program doesn't include any editing tools at all.
Nuance PDF Reader is a nice alternative to other popular programs that lets you open, mark, share and convert PDF files.
