JPG Joint Photographic Experts Group
JPG (JPEG) is a widely used image format known for its lossy compression, developed by the Joint Photographic Experts Group in 1992. This format is particularly effective for photographs and images with smooth gradients, as it significantly reduces file sizes while preserving visual quality. JPG achieves compression through a method that discards some image data, making it suitable for various applications where small file sizes are a priority.
JPG supports 24-bit color, allowing for a rich palette of over 16 million colors. Users can adjust the quality settings from 1 to 100, balancing image quality against file size to meet their specific needs. However, the lossy nature of JPG means that once data is removed, it cannot be recovered, and repeated saving can lead to cumulative quality degradation.
This format has become the standard for digital photography, supported universally across devices and platforms. It is particularly effective for online images, social media, and email attachments, where quick loading times and reduced storage requirements are essential.[1][2]
