File extension miff is used for Magick Image File Format, abbreviated MIFF, an image format used by ImageMagick. It is used to store bitmap images platform-independently.
The Magick Image File Format (MIFF) is ImageMagick's own platform-independent format for storing bitmap images. It has an advantage over other image formats in that it stores all metadata known to ImageMagick (e.g. image color profiles, comments, author, copyright, etc.), whereas, other formats may only support a small portion of available metadata or none at all. A MIFF image file consist of two sections. The first section is a header composed of keys describing the image in text form.
Except for ImageMagick, some alternative graphics viewers/editors can work with this format.
ImageMagicks supports many graphics formats, so export of MIFF format to other files is certainly doable.
