Why should I use this WebP compressor?

Developed by Google and long touted as a JPEG successor, the WebP format offers lossless compression in addition to slightly superior lossy compression to JPEG. Additionally, it adds the ability to create images with transparency that JPEG lacks.

Compress-Or-Die allows to set the compression strength of the transparency independently from the rest of the quality and to sharpen the color edges, which counteracts the 4:4:4 chroma subsampling that the WebP format lacks. All settings made can of course be previewed in the browser before the graphic is finally downloaded.

There are a lot of articles about online image compression tools in the net, most of them are very superficial. Usually they end with a simple: "It generates smaller pictures, so it's got to be better."

Learn why such statements are most of the time meaningless, understand the technical background, and find out which tool you should use as of today.

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
