When it comes to viewing images on Windows, there are many free apps including the default picture viewer of Windows. Each of these apps have their own unique interface and features. ImageGlass is a yet another freeware, but powerful image viewer and converter for Windows. The app is pretty useful if you want to view PNG and GIF images properly as many of the viewers does not show GIF animations properly. ImageGlass loads images faster than Photo Viewer, because of the feature that uses RAM to preload the next image.
ImageGlass can show the thumbnails of the images in the folder and quickly move to any image without any delay. There are also options to alter the background, toggle a full-screen view, display thumbnails, and access the program’s settings which includes the ImageBooster feature, a slider that designates specific amounts of system memory to loading the next image in a series.
You can also add a context menu item to open images with ImageGlass. You can convert images to various popular format from the application interface. Overall, a pretty good image view and converter for Windows.
