IrfanView 4.42 Beschreibung des Entwicklers
irfanView (pronounced ear-fan-view) is designed to be simple for beginners yet powerful enough for professionals or advanced users. It was the first Windows graphic viewer with Multiple (animated) GIF support, and one of the first graphic viewers with Multipage TIF support. It was also the first graphic viewer with Multiple ICO support.
irfanView supports many file formats, and includes support for select RAW file formats, so you may be able to edit files right off your digital camera, before you convert them to a more popular format. It also supports Adobe Photoshop filters, allowing you to bring power to an easier to use editing program, all this even before you consider its own drawing and editing tools.
One of the best things about irfanView is that it runs from a single executable file. It doesn't require any dynamic link libraries (DLL's) that may be installed or scattered across your hard drive in order to run. It also doesn't contain any registration or nag messages. The application is free, though the author does appreciate monetary support through donations.
