Finally understanding PNG
This article is the follow-up article to Finally understanding JPG, which I would like to recommend to anyone who would like a deeper but generally understandable introduction to JPG compression. This time however I would like to explain the functionality of a PNG and will show you at the end of the article how you can reduce the file size of your PNGs.
As with the previous article, I will present some aspects in a simplified way if it facilitates understanding, because no one is helped by mathematician buzzword bingo and few of those who would like to reduce their image sizes are mathematicians, but more likely webworkers or digital advertising specialists.
In order to be able to compare file sizes resulting from the use of different tools (compress-or-die.com, Photoshop, TinyPNG and Co.), I would like refer you to the section Comparable file sizes in the JPG article.
In the course of the article, I will continue to work with this image and bring you closer to the subtleties that lead to this fact.
