PNG description
Portable Network Graphics (PNG) is a bitmapped image format that employs lossless data compression. PNG was created to improve upon and replace GIF (Graphics Interchange Format) as an image-file format not requiring a patent license. It is pronounced /ˈpɪŋ/ or spelled out as P-N-G. The PNG initialism is optionally recursive, unofficially standing for “PNG’s Not GIF”.
PNG supports palette-based (palettes of 24-bit RGB colors), greyscale or RGB images. PNG was designed for transferring images on the Internet, not professional graphics, and so does not support other color spaces (such as CMYK).

Basic understanding of web formats
There are only three graphic file formats that are used on the web: JPEG, GIF and PNG.
The most important thing to understand is when to use each type. JPEG, GIF and PNG use very different forms of encoding and compression of the data that give them quite different uses.
GIF and PNG files work best on text, text-art, cartoons, drawings, ilustrations, any art which needs transparent backgrounds.
GIF is limited in the total number of colors to 256 or less. PNG is more advanced and can handle true color images, but doing so significantly increases file size.
JPEG on the other hand works best on photographs. JPEG does not handle sharp edges and can produce artifacts due to his lossy compression.
But let’s learn more about each format.
