JPEG (image file format)

JPEG is a common image file format used to store digital pictures, especially photographs. It works by compressing the image data to reduce file size while maintaining good visual quality. This compression involves analyzing the image's colors and details, then simplifying less noticeable aspects, which makes the file smaller for easier storage and sharing. When you open a JPEG, the image is reconstructed for viewing. This format is widely supported across devices and applications, making it popular for everyday use, including online sharing, printing, and storing personal photos.
