The MIFF (Magick Image File Format) is a versatile image format used primarily by ImageMagick, a software suite for creating, editing, converting, and displaying bitmap images. It is designed to store bitmap images with a high degree of flexibility, supporting various depths and color spaces, including transparency and multiple layers. MIFF files are often used for temporary storage during image processing tasks, as they can efficiently preserve the full quality and attributes of images.
Image file format related to the .PNG format, but uses lossy compression like standard .JPG files; developed as a sub-format for .MNG objects, but can also be used as a standalone raster image format.
