PNG files (pronounced "ping") are great! They're among the highest-quality images on the web. 24-bit PNG's use lossless compression so they retain all their clarity and a perfect-pixel image. What's more, they support alpha transparency! It's no wonder that PNG files are among the most widely used image formats on the web.
But it's not all sunshine and puppies for PNG files. They do have one giant drawback: they take up a LOT of space!
PNG Compressor will "compress" (that is, quantize and convert) your 24-bit PNG images into 8-bit PNG's, preserving your transparency and finding a great balance between filesize and quality.
Q: Does this affect the quality of the image?
A: Technically yes. But in most images you won't notice the difference. Occasionally, in some logos or images with smooth gradients, you may see some color banding or dithering.
