PNG-8 use 8-bit colors (256 colors), it has a smaller size and higher compression. PNG-24 use 24-bit colors ans has better image quality, but it has a large size. PNG-32 add 8 bits transparency information to 24-bit image, so it supports semi-transparent. Related Image Converter ...
PNG,可移植网络图形格式(Portable Network Graphic Format,PNG)名称来源于非官方的“PNG's Not GIF”,是一种位图文件(bitmap file)存储格式。PNG用来存储灰度图像时,灰度图像的深度可多到16位,存储彩色图像时,彩色图像的深度可多到48位,并且还可存储多到16位的α通道数据。
pngquant is a PNG compressor 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 ...
