That's me

Christoph Erdmann

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.

COD says Goodbye
2026-06-24

After 10 years of compress-or-die.com, it’s time for me to say goodbye. It’s been a great time—I’ve learned a lot technically, but I’ve also met some wonderful people.

compress-or-die.com was created back then to get the most out of graphics for small banners. At the time, I was still working at an advertising agency. And over time, it just kept growing and growing.

But some of you may have noticed that over the past two years, there have been hardly any changes, and there hasn’t been much from me to read—which was quite different back in the day.

But a lot has changed in my personal life: children, new and different hobbies, and health issues have shifted my focus in other directions. And so, I had less and less time and motivation left for this project that was once so close to my heart.

For this reason, this chapter is now coming to an end. I’d like to thank all of you for using COD and for providing such great feedback, which helped COD grow so much.

I’d especially like to thank the Patrons who have covered the server costs over the past few years. Thank you so much!

On July 25, 2026, I will send COD into its well-deserved retirement.

All the best to you all,
Christoph
