What does JPEG mean?

JPEG: The full form of JPEG is Joint Photographic Experts Group. JPEG was invented to make huge image files into small file size. It compresses the files by 90%, and cuts the file size to 1/10th of the original. Mainly the JPEG files are used in websites. Because it is almost feather light in terms of file size and enables the web pages to open in the browser faster. JPEG files do not maintain the full image quality. It reduces the quality of the image comprehensively. Thus from the JPEG file original image is not recoverable. Generally TIF, PNG, BMP are loss less in terms of image quality. That means these files maintain 100% image quality of the original. But JPEG goes the other way. JPEG manipulates the pixel data for more convenience. If any detail of the image is causing problems for compression, it can be ignored. This allows tremendous file size reduction. It makes JPEG different from the other image file formats.
