TinyPNG uses smart lossy compression techniques to reduce the file size of your PNG files. By selectively decreasing the number of colors in the image, fewer bytes are required to store the data.
It was such a simple yet flawless experience. I discovered it while working on the launch of my newest product and it became instantly part of my workflow from there!
I've been using TinyPNG to reduce the size of our website images for a couple of months now and it's an incredible service. It's fast, reliable and non-intrusive.
Great work!
