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! Iβm 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.
Thank you very much to all Patrons!

Here it is, the brand new SVG Compressor: compress-or-die.com/svg π It's actually based on "svgo", but I added an "Extreme compression" option which reduced the file size by 6 to 16% in my experiments. At the moment it is experimental π§ͺ and I appreciate your feedback.
I wrote a blog post to give an overview/comparison of the next-gen image codecs #JXL, #AVIF, #WebP, predicting once again the end of the #JPEG, but this time for real (I hope). cloudinary.com/blog/time_for_β¦
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]
she paid the hosting bills for the next months. Thanks a lot, "mad scientist". [2/2]
