The application's interface is plain and partly truncated at the bottom, though none of the buttons were cut off. We tried to resize the window but were unable to do so. The program is broken down into four steps that are labeled on the interface. First, we had to select the input directory and add the PDFs we wanted watermarked. Second, we entered the text for the watermark. … Read more

Nuance's first free PDF reader is a strong entry to the growing field of zero-cost Adobe Reader alternatives. It has a reasonable set of features, including free document conversion via the Nuance Web site, and a crisp interface that should be accessible to anybody.

Nuance comes with two toolbars. The one at the top of the program is loaded with big icons, but avoids clutter by hiding most of the secondary tools behind drop-down arrows. The toolbar at the bottom contains PDF-relevant details, such page number, zoom percentage, and viewing format. It's bigger than in most competitors, though, … Read more

We're not sure we've ever seen a PDF converter that's so abjectly bad.

For starters, it closes any open Office documents, without warning. We found this out the hard way when we tested the program, wrote part of this review, … Read more
