Joint Photographic Experts Group (JPEG) is a widely used image compression standard that reduces the file size of digital images while maintaining acceptable quality. JPEG uses lossy compression, meaning that some image data is discarded to achieve smaller file sizes, making it ideal for storing and sharing photographs online. The degree of compression can be adjusted, allowing users to balance between image quality and file size. JPEG files are commonly used in photography, web design, and social media. Despite newer formats like PNG and WebP, JPEG remains one of the most popular image formats due to its compatibility and efficiency.
