Irfanview is one of the best free picture viewers - and has been for more than 12 years.
The free picture viewer has been available for more than 12 years and is updated regularly. The program supports almost all image file formats, but audio and video files, too, and offers simple editing and powerful conversion features, supports Photoshop filtering and much more. Thereby it is extraordinarily small with a size of about one Megabyte, works very fast and doesn't touch the registry when installed.
Irfanview has been updated to version 4.20, which delivers that much improvements that listing all of them would go beyond the scope of this article, but they can be found here. You can download the tool from our servers or from the official homepage.
