JPEG (Joint Photographic Experts Group) is a widely used image format known for its efficient lossy compression, balancing image quality and file size. It is ideal for photographs and complex images with gradients.

JPEG supports 24-bit color depth, allowing for millions of colors, but does not support transparency. Its widespread compatibility across devices and platforms makes it a standard choice for web images. However, repeated editing and saving can degrade quality due to cumulative compression artifacts.
