PNG  is used for images it is a file format, it can be used by everyone it is a free file there are many advantages in using PNG, the minor advantage only that it can be used by anybody, the present PNG format is the replacement of the older PNG format and in few ways it is the replacement of the TIFF format also. The PNG is used mainly in things they are World Wide Web and image editing. PNG is considered to be the better one when it is compared to GIF, it has got alpha channels that has transparency and gamma corrections which corrects the

"The type of a PNG image is defined in the IHDR image header. The image has a certain bit depth, up to 16 bits per sample, and a certain color type, from Grayscale to RGB+Alpha. If two PNG files of different types represent exactly the same image, each file can be regarded as a lossless transformation of the other. A lossless transformation can reduce the uncompressed stream, and such a transformation is named image reduction. In most cases, image reductions are capable of reducing the compressed stream (which is, in fact, our interest), as an indirect

Compression PNG's compression is among the best that can be had without losing image information and without paying patent fees, but not all implementations take full advantage of the available power. Even those that do can be thwarted by unwise choices on the part of the user. PNG supports three main image types: truecolor, grayscale and palette-based ("8-bit"). JPEG only supports the first two; GIF only the third (although it can fake grayscale by using a gray palette). The impact on compression comes from the ability to mix up image types in
