Almost 500 formats can be viewed, edited and converted. Perhaps the most important feature of this program is its design. It looks and feels almost like Windows Explorer. This means that most users ‘ even novice computer users ‘ should not have any problems using it. All the folders are displayed in the left pane. The files are displayed in the upper half of the right pane. When you select a file, it is displayed in the lower half of the right pane. Simple and effective!

Of course, you can view everything by double-clicking the file without the need to use a third-party application. You have many options when it comes to editing images. You can resize, rotate and crop them with ease. Also, you are able to adjust the brightness and contrast of your photos, as well as use Auto Levels and Auto Contrast to quickly enhance the images.
