PNG v/s JPG

Please explain difference between PNG and JPG?

Portable Network Graphics or PNG is a lossless compression file format, its a common choice for use on the Web. PNG is a good choice for storing line drawings, text, and iconic graphics at a small file size while Joint Photographic Experts Group or JPG is a lossy compressed file format. It is more useful for storing photographs at a smaller size.

JPEGs are for photographs and realistic images. PNGs are for line art, text-heavy images, and images with few colors.

This is image file format. PNG means portable network graphics and JPG means joint photographic experts group.

In short png's size is very less and supports transparent background and jpeg is the exact opposite its size is huge and doesnt support transparency.
