Let’s take a look at these two formats
A file with the extension JPG also known as JPEG is a format created by the Joint Photographic Experts Group and belongs to the category of bitmap images. This extension is commonly used in the great majority of digital cameras. Up to the present JPG file is the most common graphic format of a compressed image. JPG uses a rather high compression ratio, nevertheless, it can boast a color depth support of 24 bits. A great number of web developers use images in JPG format because there is a possibility of reducing the size of the picture without serious loss of quality and shades.
A file with the extension PNG or Portable Network Graphic refers to bitmap images as well. The PNG format contains a certain palette of colors used in the drawing. Such graphic format is often used in the network of the World Wide Web. Due to the use of the Deflate compression algorithm, bitmap images with PNG file extension are available for compression without obvious losses in quality. Among the owners of web resources, PNG images are famous for their excellent characteristics against the background of such formats. It is also worth noting, that PNG supports a color depth of up to 48 bits.
