Portable Universal Viewer

Portable Universal Viewer is an application that lets you access files of multiple formats, including text documents, images, videos and audio tracks.

Since installation is not necessary, you can simply place Portable Universal Viewer on an external device and directly run the executable file on any computer. More importantly, no changes will be made to your Windows registry items.

The interface of the software is plain and intuitive. You can import files by using the file browser or the "drag and drop" method.

You can save the current file, rename or delete files, create links to them, as well as use a search function.

But you can also change the viewing mode for text (e.g. word wrapping, encoding), multimedia (e.g. fit image to window, grayscale, invert) and Internet (e.g. offline browsing).

You can zoom in and out, switch to full screen mode, select the viewing mode (e.g. image, text, HEX, plugins), as well as enable Portable Universal Viewer to stay on top of other applications and to remember the last window position.

In "Settings" you can change the interface language and icons, integrate the tool in the Explorer shell extension, allow only one single instance, set file associations, modify text options (e.g. font and colors, auto-reload, search), multimedia properties (e.g. show image transparency, loop playback), shortcuts, history options (e.g. save the recent files list) and others (e.g. use custom window height for modes, startup view mode).

The tool runs on a moderate amount of system resources and has an excellent response time. Unfortunately, we couldn't access the help file. Also, we accidentally selected the image mode when a text document was opened and this triggered an error (we were forced to restart the program). To conclude, Portable Universal Viewer is an excellent program for viewing files in popular formats and we highly recommend it to all users.
