compression
to the
max!
This is the image compressor for professionals, specifically designed for tasks where you have to squeeze out the last byte of your images. But you can use it of course for all your images. It's free to use.

The big image compression tool comparison
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.
Finally understanding JPEG
If you always wanted to know how the JPEG compression works under the hood I want to recommend this article to you. It was important to me to write an article that is reasonable for every level of understanding.
Furthermore it contains 7 valuable tricks to reduce the file size of your JPEGs by exploiting the technical functionality of the JPEG compression algorithm.
Finally understanding PNG
Ever wondered why some of your PNGs are of large file size while similar PNGs are so small?
Since this question comes up so often, I have written a follow-up to my article "Understanding JPEG" to explain the bare necessities of the PNG compression algorithm in layman's terms.
At the end you will also get 7 tips on how to get your PNGs to a REALLY small file size.
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.
Many thanks to the MINISTRY Group for hosting COD.

From now on compress-or-die.com/jpg always embeds the unit inch for the resolution, because the unit cm seems to be problematic for some programs (e.g. Outlook and Apple Mail).
A closer look at how to load different preview images from progressive JPEGs with the help of Ajax and HTTP range requests. Also, @McSodbrenner introduces the Embedded Image Preview (EIP) technique ↬ Faster Image Loading With Embedded Image Previews smashingmagazine.com/2019/08/faster…
