The main characteristics of JPEG or JPG format:

  1. The standerd file format of the most digital cameras is JPEG or JPG format which supports 16 bit of data format.
  2. When the size of the file is main subject than the quality of the file, then you can use this format. So, this format is the best for small size of data.
  3. For using in website, the JPEG format can compress the image, approximately, from 60%-75%. The small size of file is uploaded very fastly.

But, for the line art, we are adviced not to use JPEG format. On the otherhand, in where the sharpness of image is most important, in there we are adviced not to use JPEG format. In this type of case, you may use PNG or GIF format.


GIF : Graphics Interchange Format 

Stands for “Graphics Interchange Format.” GIF is an image file formatcommonly used for images on the web and  in software programs. Unlike the JPEG image format, GIFs uses lossless compression that does not degrade the quality of the image. However, GIFs store image data using indexed color, meaning each image can include a maximum of 256 colors.  The Graphics Interchange Format (better known by its acronym GIF /ˈɪf/ or /ˈɡɪf/) is a bitmap image format that was introduced by CompuServe in 1987[1] and has since come into widespread usage on the World Wide Web due to its wide support and portability.

So, guys let’s have look for the characteristics and uses of this picture format :
