IrfanView is a very fast, small, compact and innovative graphic viewer for Windows. It is trying to be simple for beginners and powerful for professionals. IrfanView is a fast, simple freeware image viewer and editor that supports all major graphic formats, including BMP, DIB, JPEG, GIF, animated GIF, PNG, PCX, multipage TIFF, TGA, and more.
In addition, it features drag-and-drop support, directory viewing, TWAIN support, slide shows, batch conversion, and modifications such as color depth, crop, blur, and sharpen.
IrfanView is trying to create new and/or interesting features in its own way, unlike some other graphic viewers, whose whole “creativity” is based on feature cloning, stealing of ideas and whole dialogs from ACDSee and/or IrfanView!.
