Image formats like PNG allow compressing the data that they contain to represent a given image.

It is possible to achieve different levels of efficiency by varying several compression parameters.

This class can optimize the compression efficiency of PNG images by using different PNG image optimization programs and keeping the output of the program that gave the best results.
