Part 3. Know the Basic Difference Between JPG and JPEG

a. What is JPG or JPEG?

Standing for Joint Photographic Expert Group, JPEG/JPG is among the most widely used image format. The image file comes with .jpeg or .jpg extension and is majorly used for capturing images by the digital cameras as well as other image capturing devices. Being a compression format, JPEG/JPG is also popularly used for image transmission and uploading it over several sites on the internet. Using lossy compression, the ratio of compression can range from 10:1 to 20:1 ratio to suit your storage and other requirements. During the compression process, pixel blocks and image sections are removed, and thus, image quality is reduced in the process.

b. Are the JPEG and JPG Same?

JPEG and JPG are the image file extension, and the only difference between the two is the number of characters which are used. The earlier versions of the Windows systems like MS-DOS and others were capable of reading and handling the files having a three-character extension and thus .jpg was used. The limitation was not applicable on the Unix and the Mac system, and they used .jpeg as their extension.

The present-day system can now handle four-letter characters, and .jpeg files can now be used on Windows systems as well. Adobe Photoshop, GIMP, and other image editing tools also save their image files on the .jpg file.

Another difference between the two formats is in their file quality and size. JPG file is capable of preserving the quality along with less data redundancy after the compression method, and thus the size of these files is more.
