This tool is used to convert Graphics Interchange Format (gif) to Portable Network Graphics (png).

GIF is a bitmap image format that was developed by a team at the online services provider CompuServe led by American computer scientist Steve Wilhite on June 15, 1987.

PNG is a raster-graphics file-format that supports lossless data compression. PNG was created as an improved, non-patented replacement for Graphics Interchange Format (GIF).
