Why is JPEG used?
A JPEG is a standardised lossy compression mechanism for digital images. Digital cameras compress raw photographs as JPEG images to make the files smaller in size. It is the most common file format for photo storage. JPEGs became popular as they save more storage space compared to older formats such as Bitmap.
What is JPG and JPEG file?
JPG (or JPEG), is a popular file format used for images and graphics—especially on the internet. It was created by the Joint Photographic Experts Group (JPEG) and uses a compression algorithm that reduces sections of an image into blocks of pixels.
