STDU Viewer is a powerful Windows application designed to let you view the content of the most popular document formats out there with just a few clicks.

With a clean and well-organized interface, STDU Viewer is able to handle an impressive lineup of file extensions, including TIF, PDF, TXT, FB2, DCX, DJV and XPS.

It offers just a few tools to help you control the documents content, including a hand tool, a text and image selector, zoom selection and sync content.

In addition, the program enables you to create your very own bookmarks, thus giving you the power to access certain sections of the opened documents quick and easy.

The “Options” screen is another important section of the application because it allows you to set up basically everything about STDU Viewer, including navigation tabs and the way they look.

Last but not least, you can configure printing, text and FB2 documents, shortcuts, set up scrolling and screen tapping and customize session control.

It's absolutely no surprise that STDU Viewer runs flawlessly on every single Windows workstation, with only a small amount of resources needed to serve its purpose. One of the most impressive things about STDU Viewer is its speed, as every single document is opened in no time, while other applications need at least a few seconds to complete the task.

The conclusion is rather simple: STDU Viewer is a great tool, not only because it's freeware, but also because it helps you open many document formats using just a single application, thus replacing dedicated tools for different extensions.
