The High Efficiency Image File Format (HEIF) is a modern image format designed for superior compression efficiency and enhanced image quality. Originating in 2015, HEIF was developed by the Moving Picture Experts Group (MPEG) and utilizes the High Efficiency Video Coding (HEVC) codec to store image data. It supports a wide range of multimedia applications, including single images, image sequences, auxiliary image items, and non-image items, making it highly versatile for professional and consumer usage in various devices and platforms. Its ability to maintain high image quality while reducing file size significantly improves storage efficiency and accelerates data transmission.
The CAL file extension, known as CALS (Continuous Acquisition and Life-cycle Support) Type 1 Image, is a 1-bit black-and-white raster image format developed by the U.S. Department of Defense in the mid-1980s to standardize graphics data interchange for military documentation. It is primarily used for storing and sharing monochrome images while retaining orientation metadata. The format supports both uncompressed and compressed (using CCITT Group 4 compression) images.
