What Is a JPEG File Format?

JPEG, short for Joint Photographic Experts Group, is the most widely used image format in the world, especially for photographs and complex images with smooth color gradients. JPEG uses lossy compression to significantly reduce file size by removing some image data that is less noticeable to the human eye, striking a practical balance between quality and storage efficiency.

Because nearly every device, browser, app, and printer supports JPEG, it remains the default choice for sharing photos online, sending images over email, and storing pictures on smartphones and cameras.
