Hi! I’m Christoph, working as a programmer/developer in Bielefeld/Germany.

Since I was building an advertising tool, I had to learn a lot about image file formats and compression.

This tool is some kind of a by-product and turned out to be my sweet little baby. So have fun using it! I hope it will help you as much as it does for me.

Many thanks to the MINISTRY Group for hosting COD.
