Nitro Reader allows viewing PDF documents. Besides, it supports other basic operations, like converting, protecting and commenting this type of files. The application is very easy to use, mostly because its interface resembles those of Microsoft Office products. In this regard, it has the typical layout made of a ribbon with tabs that appear according to the context. Besides, some navigation panes can come out to perform specific actions. It is also very convenient that the tool uses tabs to display various documents in the same window at the same time.

Besides its main feature of allowing to read PDFs, the application lets you create new documents from scratch as well as from other existing files. Luckily, documents created with such popular suites as Microsoft Office and Corel as well as plain text files and various image formats are supported. Moreover, if you want to open a much wider list of more than 200 other formats, you should pay for the Pro version. When creating a new document from other files, three quality settings are available: Web-ready, Office-ready and Print-ready, with different definitions and sizes.

Fortunately, it supports converting not only from other formats to PDF but also converting a PDF to text and extracting images as separate files. Unfortunately, you cannot decide on what output picture format to use, as JPG is the only extension supported. Another way to extract contents is using the Select tool to grab a given text segment or take a snapshot of a specific area of the visible page.

The application also supports reviewing a PDF by adding text, comments and notes as well as marking up specific text segments. Furthermore, you can protect the contents of a document by applying a set of restrictions. Finally, it is also possible to digitally sign your files.

In general, Nitro Reader has most of the features that are available from other similar tools. It provides the advantages of having a nice user interface and loading documents rather quick. Unfortunately, some features, such as converting a PDF to Word, are only available from the Pro version.
