Photoresampling is software that can process digital images by smoothing and focusing picture details while resizing them.

One of the standout features of PhotoResampling is its ability to work with a wide variety of algorithms, including Catmull-Rom, B-spline, Mitchel-Netravali, GB1, GB2, GBMX, Bilinear, Lanczos, and GBLS. Speaking of GBLS, this algorithm was personally created by the developer and is widely considered to be one of the best options for enlargements of 250% or more.
Overall, we were impressed with the flexibility and power of PhotoResampling. The program can handle images of virtually any size, and its intuitive interface makes it easy for users of all levels to navigate. Additionally, the software's ability to process high-quality images quickly and efficiently is truly impressive. If you're serious about improving the quality of your digital photographs, then PhotoResampling is definitely worth considering.
