As the standard image PNG was designed to replace GIF as the standard image format for the comprehension on the internet. The comprehension of PNG is better than GIF it has got full alpha transparency and gamma correction, the common browsers support PNG, and it is recommendation of the W3C. In one way the binary transparency is equal. Research is done taking three simple graphics the first one is the palate of 64 colors, and the next one with 128 colors and these are compressed in three different ways, in Photoshop when compared the pictures with one

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

PNG is a file format used especially for images. It is a free file format, meaning that it can be used by everyone in any way he wants it without paying any royalties to anyone. But this is not the main advantage of PNG, I would even call it a minor advantage, as the end-users do not quite feel it. The PNG format was intended to be a replacement for the older PNG format and, in some ways, to the TIFF format. It's mainly used in two areas: World Wide Web and image-editing. On the Web, PNG is much better that GIF. It has included

This material is intended to inform the simple users about the features of the PNG format. So, it will pass over some details like for example the freedom from patents, as this has no connection to the end-user, being more of a concern for the developers. The PNG format was intended to be used like a substitute for the GIF and TIFF formats. So, it was created with two main ways of usage in view: World Wide Web Image editing PNG can be widely used for the web, having several advantages over the GIF format: the possibility of

APNG comes as a modification of the well-known PNG format, but with additional support for animation. It supports 24-bit images and 8-bit transparency, having a much better quality then the classic GIF format. An APNG file contains ordinary PNG frames, with two additional data chunks: aDAT (animation data chunks) and fCTL(the frame control chunk). Any PNG decoder should be able to decode the first frame of the APNG file as an ordinary PNG image. Any APNG data file must be subjected to certain rules: The size of the entire APNG

"For the Web, PNG really has three main advantages over GIF: alpha channels (variable transparency), gamma correction (cross-platform control of image brightness), and two-dimensional interlacing (a method of progressive display). PNG also compresses better than GIF in almost every case, but the difference is generally only around 5% to 25%, not a large enough factor to encourage folks to switch on that basis alone. One GIF feature that PNG does not try to reproduce is multiple-image support, especially animations; PNG was and is intended to be a

Bill Bither likes the PNG format for graphics. In the start of his article, he lays out some of the nifty features that separate it from GIF and TIFF file formats. But there's more. "However, perhaps the best thing a PNG has to offer is what's called the alpha channel. An alpha channel is one byte of extra data per pixel (or palette entry for 8-bit images) that represents the transparency level of a pixel. A PNG image with alpha is capable of 256 levels of transparency. What does all this mean? For one thing, you can antialias text and images so

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
