What is PNG?
Known as Portable Network Graphics, PNG is a bitmap image file format for the lossless, portable, well-compressed storage of raster (bitmap) images. The initial purpose of PNG creation is to develop a patent-free image file format to replace GIF with much more functionalities, to some extent, the much more complex TIFF format. Unlike other simple image file format, PNG support indexed-color, grayscale, and true color images, plus an optional alpha channel for transparency.
PNG can be used in many fields, and image-editing and transferring images on the Internet are two major uses. For web transferring, PNG supports alpha channels, gamma correction, two-dimensional interlacing and better compression than GIF. As for image-editing, up to 48-bit true color or 16-bit grayscale is supported by PNG for restoring and re-saving an image without image quality reductions.
