Convert JNG to MIFF

The JPEG Network Graphics (JNG) file extension is designed for storing JPEG-encoded image data within the PNG file format. Introduced as part of the MNG (Multiple-image Network Graphics) format, JNG was created to provide a flexible, high-quality image format that supports both lossy and lossless compression. It is particularly useful in applications requiring the integration of JPEG compression within a wider range of data types and multimedia elements. Though not widely adopted, JNG offers enhanced compatibility and versatility for complex imaging tasks in computer graphics and web development.

The Magick Image File Format (MIFF) is a platform-independent format developed by John Cristy for ImageMagick, designed to store bitmap images. MIFF supports extensive metadata, including image color profiles, comments, and copyright information, making it versatile for various applications. It is particularly useful in image processing and conversion tasks due to its ability to handle multiple image formats like JPEG, TIFF, and PNG. MIFF's history dates back to its inception as part of the ImageMagick toolkit, which is widely used for image manipulation across different platforms.
