The JPEG (Joint Photographic Experts Group) image format is a widely used and highly efficient compression method for photographs and images with a rich color palette. It employs lossy compression to reduce file sizes while maintaining an acceptable level of visual quality. JPEG files typically have the extensions .jpg or .jpeg and are commonly utilized for digital photography, online images, and graphics where a balance between file size and image quality is crucial. The format is suitable for scenarios where some loss of detail is acceptable in exchange for significantly smaller file sizes.
