Is higher compression level better?
The higher the compression ratio, the smaller the file size (more data is packed into a smaller space), but the lower the quality of the compressed product.
Does PNG compression affect quality?
Unlike JPEG files that get terrible picture artifacts with heavy compression, PNG's use lossless compression, meaning compression doesn't impact image quality.
How do I compress a PNG even more?
One of the most basic ways to cut down on a PNG's file size is to limit the number of colors that the image has. PNGs can be saved as Grayscale, Truecolor, Indexed-color, Grayscale with alpha, and Truecolor with alpha. Being saved with alpha means that the PNG also has transparency.
