What is PNG?
PNG format is the Portable Network Graphics. Portable Network Graphics (PNG) was created as an option for the GIF typical, partly because of legal entanglements resulting from GIF’s use of the patented LZW compression scheme, and partly as a result of GIF’s a lot of restrictions. PNG is superior to GIF in a great deal of approaches, supplying the subsequent functions:
Images that are the identical size or somewhat scaled-down than their GIF counterparts, though trying to keep lossless compression. Here you can check out How to convert png to pdf easily.
Support indexed colors, gray-scale, and RGB (an extraordinary variety of colors).
Assistance for 2-D progressive rendering, that’s determined by pixels as opposed to lines (as in interlaced GIFs and progressive JPEGs); this indicates that contents of a progressively rendered PNG file develop to become obvious previously inside the load strategy.
An alpha channel that tends to make it probable for an image to get a number of opacity; whereas GIFs only permit an offered pixel to turn out to be totally transparent or totally opaque, this purpose makes it possible for you to generate pictures with degrees of transparency, considerably better blending pictures with their backgrounds.
Gamma correction, which makes it possible for you to correct for differences in how an image will seem on various laptop or pc exhibit strategies.
File integrity checks, which help stay away from difficulties while downloading or transferring PNG files

Most graphics apps and all browsers are all support PNG format.

Advantages:
- The PNG format supports compression level lossless.
- It supports alpha channel transparency.
- It supports gamma correction.
- It supports interlacing.
- It is supported by web browsers latest.
Disadvantages:
- Browsers and older programs may not support PNG files.
- As an Internet file format, PNG provides less compression than the lossy compression of JPEG.
- As an Internet file format, it offers no support for multi-image files or animated files. The GIF format supports multi-image files and animated files.
