JPEG, which stands for Joint Photographic Experts Group, is a popular image format used for storing digital photos. It uses a method called compression to reduce the file size, making it easier to share and store images without taking up too much space. This compression works by removing some details that the human eye may not easily notice, allowing for smaller files while still maintaining good quality. Many people use JPEGs for their photos because they balance quality and size well. Whether you're sharing pictures on social media or saving memories on your computer, JPEGs are a convenient choice. They are compatible with most devices and software, making them a go-to format for digital images.
