Detailed explanation-1: -PNG or Portable Network Graphics files are a lossless image format originally designed to improve upon and replace the gif format. PNG files are able to handle up to 16 million colors, unlike the 256 colors supported by GIF.
Detailed explanation-2: -What is a PNG file? PNG is short for Portable Network Graphic, a type of raster image file. It’s particularly popular file type with web designers because it can handle graphics with transparent or semi-transparent backgrounds.
Detailed explanation-3: -JPEGs and PNGs are both types of raster image files. This means they’re made up of a fixed number of color pixels-rather than the grids, points, and mathematical formulas used in vector files. Raster files allow plenty of detail to be displayed but lose their resolution when significantly resized.
