-[pngquant](https://pngquant.org) is a PNG compresor that significantly reduces file sizes by converting images to a more efficient 8-bit PNG format *with alpha channel* (often 60-80% smaller than 24/32-bit PNG files). Compressed images are fully standards-compliant and are supported by all web browsers and operating systems.
