JPEG File Extension

A file with JPG suffix is an image file saved in a compressed picture standardized by the Joint Photographic Experts Group (JPEG). JPG is a commonly used method of lossy compression for images because the compression algorithm reduces the size of the original file. Jpg file extension made an image file ideal for sharing, storing, and showing on websites. JPG compression technique reduces the image quality, which is easily noticeable if the image file is highly compressed. There is also some alternative jpg standard exist that compresses the image file without loss of data, like JPEG 2000, Lossless JPEG. Many BMP (Bitmap Images) are saved in .jpg format in order to compress the file size. Nowadays JPEG / JPG image compression also used by most of the cameras.
