In this short tutorial I will show you how to open and view AVIF image files with KDE image viewer, Gwenview.

Install the following packages: kimageformats, shared-mime-info and libavif using your system package manager. You will be able to view AVIF files and see the thumbnail on the file manager, Dolphin (you may need to press F5 inside Dolphin to re-draw the thumbnails).
