Having a good image viewer on your system is a must, especially if your photo collection spans across many gigabytes and includes thousands of pictures. Among the best solutions out there, XnView aims to offer a pleasant experience to all users.
Packing so many features that it can challenge even the likes of IrfanView, this application comes with support for several hundreds of file types.
The interface is very easy to understand and highly-customizable. All the functions are at hand and the fact that the GUI supports tabs is a great addition. You can open as many images as you want and then simply move from tab to tab instead of reusing the same canvas for loading the pictures.
Right-click any picture you want and a whole new dimension opens its doors. The context menu allows you to start a batch conversion or renaming, send the photo by email, move or copy it to a certain folder, tag and rate it, set it as wallpaper and many other things.
You should note that the right-click menus for images loaded in their tab and for those displayed in the file browser are different, so there are indeed a lot of goodies under the hood that wait for you to uncover.
What we found really impressive during our test was the quick conversion feature that enables you to right click a photo and turn it into JPEG, TIFF, BMP and PNG formats in a second. Also, the list of transformations you can add to a set of photos you are about to convert is astounding.
All things considered, XnView is definitely one of the best tools of its kind, so if you're looking for a photo viewer, converter and manager, this one should be among the top picks.
