Two tools in one. As an image viewer, ACDSee Classic stands unsurpassed in its ability to quickly decode and display images. Since ACDSee Classic is an image viewer and not an editor, less memory is required to view images. A distinctive feature of ACDSee Classic is incremental display, whereby images are displayed on the fly as they are decoded. As an image browser, again ACDSee Classic is the best choice for exploring your file system for images of interest. A high-speed preview feature lets you quickly and easily take a peek at images without interrupting or slowing down your exploration. Now with lossless JPG rotate, thumbnail printing and more!
