The ISH file type is associated with the Image System (Hires), a format used for storing high-resolution images. Originally designed to handle detailed graphical data, ISH files are typically utilized in environments where image clarity and precision are paramount. These files can encompass a wide range of visual data, from digital art to sophisticated scientific imagery. Due to their high-resolution nature, ISH files are often larger in size compared to standard image formats, necessitating more storage space.
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.
