Your opinion is so important for me! Do you dream of another fancy feature which would spice up your work routine? Even if you have found a bug, don't hesitate to drop me a line. I will do my best to implement your feedback and improve this tool.

But maybe your question has already been answered in the FAQ. Take a look inside.

I am able to read/answer in German/English.


That's me

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.

A devoted Compress-or-Die user ("mad scientist") sent a welcome surprise of an unsolicited donation of $100.00 and mentioned how important the tool is to her business. She said she wanted to show her appreciation in a tangible way. I'm overwhelmed. With this donation [1/2]

Just a little question ...

In what environment do you use Compress-Or-Die most often?
