The ISM file type is associated with the Image System (Multicolor), a format used for storing digital images. It is specifically designed to support images with multiple colors, allowing for rich and detailed visual content. This format is utilized in various applications that require high-quality image representation, including graphics design and digital imaging software. The ISM file format enables efficient storage and retrieval of multicolor images, making it a practical choice for professionals and enthusiasts in the field of digital graphics.
Based on HEVC (High-Efficiency Video Coding), the HEIF format is an image file container with one or multiple images and is the default image format for Apple Live Photos. It replaced the JPEG format as it's smaller in size and has lossless compression ensuring high-quality photos.
