IrfanView is a freeware/shareware image viewer for Microsoft Windows that can view, edit, and convert image files

and play video/audio files. It is noted for its small size, speed, ease of use, and ability to handle a wide variety of graphic

file formats, and has some image creation and painting capabilities. The software was first released in 1996.

IrfanView is free for non-commercial use; commercial use requires paid registration.
