Why should I use this JPEG XL compressor?

JPEG XL is the next-generation image format that is poised to replace the currently existing formats such as JPEG (about 60% smaller with the same quality) , PNG, GIF, WebP and AVIF.

It supports transparency (alpha channel) and animation, as well as lossy and lossless modes, progressive decoding, wide gamut, HDR and much more, while being independent of any licenses.

Here you can test this image format of the future.

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
