XnView MP is recommended for photographers, graphic designers, and anyone who needs to organize, view, and edit a large collection of images. It's also well-suited for users who require bulk processing and conversion of image files.
XnView MP stands for Multi Platform = it is available for Windows, Linux and MacOS. It is a continuation of the older XnView Classic. In my opinion it is a great alternative to Windows photos app or any Linux image viewer that comes preinstalled. I even think it is an alternative to IrfanView. It is really fast and simple to use, supports more than 500 image formats, has built in folder browser, image converter, editor... AND MORE!
