JPEG compression is a method for reducing the file size of digital images while keeping them visually useful. It works by analyzing image information and removing details that are less noticeable to the human eye. The amount of compression can be adjusted, allowing users to balance image quality and storage requirements. Higher compression produces smaller files but may introduce visible artifacts, such as blockiness or loss of fine detail.
For example, a website can use JPEG compression to reduce the size of photographs before publishing them online, helping pages load faster and consume less bandwidth. It is widely used for photographs, websites, digital cameras, and online media. Its main benefits include smaller files, faster transfers, reduced storage needs, and practical image quality for everyday applications.
