JPEG uses knowledge of the way the human brain and eyes perceive color to make this loss of detail less noticeable. By contrast, the JPEG file format uses a lossy compression algorithm by which the greater the compression, the more information is lost, ultimately reducing image quality or detail that can not be restored. Some compression algorithms, such as those used in PNG file format, are lossless, which means no information is lost when the file is saved. Both cameras and computer programs allow the user to set the level of compression. When images are stored in JPEG format, compression has already taken place. Digital compression of images may take place in the camera, or can be done in the computer with the image editor. Many image file formats use data compression to reduce file size and save storage space.
