PhotoZoom Professional is a digital image editing software that can resize and enlarge images without any apparent loss of quality.

PhotoZoom Professional uses a patented, advanced interpolation method, called S-Spline, which is highly effective in resizing digital images without generating the typical interpolation artifacts.
PhotoZoom Pro can be very helpful in disciplines that require high quality image size manipulation such as desktop publishing, industrial image processing, medical applications (e.g. radiology), security (e.g. police) large printing, and also the Internet and digital photography industries.
PhotoZoom Pro is a very powerful software that has been designed to be immediately usable even by non-technical users.
Its interface is very simple and well organized, with a small set of large and highly recognizable buttons.
Once a digital image has been opened, the user needs only to specify the new size of the image (and eventual resolution) and PhotoZoom Pro does the rest. The results are displayed within a few moments on the screen, and you can see with your naked eye how images enlarged multiple times maintain their integrity and detail.
I have reviewed PhotoZoom Pro in the distant past, when its core engine technology, S-Spline, gave name to the program as well. Today, the name has changed, but PhotoZoom has become only easier to use and more powerful in providing me with fast-to-use tools that allow me to resize images even to poster size while maintaining good optical quality and definition.
