DnD Converter freeware to convert JPG and PNG. – Macitynet.it
From Japan, a utility written in Cocoa for those who need to convert Jpeg and Png: DnD Converter files on the fly. Instructions in Japanese … but intuitive and English preferences setting.
Convenient the ability to establish the quality of the file to be converted.
Strengths: the "Drag and Drop" (hence the name of the application itself "DnD Converter") but above all the fact that it is completely free. (Reported by SpiderMan)
