This tool uses a lossy compression strategy for PNGs. It intelligently reduces the number of colors in the image through a technique called 'color quantization,' achieving a higher compression ratio than traditional lossless compression. At higher quality settings, this 'loss' is often imperceptible to the human eye. If you set the quality to 1, the tool will attempt a near-lossless compression.
