Convert JNG to JPM

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 JPM file extension stands for JPEG 2000 Compound Image File Format. It is used for storing multiple images and graphics, incorporating JPEG 2000 compression to achieve high-quality visuals with reduced file sizes. JPM files are particularly useful in scenarios that require efficient storage and handling of complex image data, such as digital archiving, medical imaging, and document management. Developed as part of the broader JPEG 2000 standard, the JPM format was introduced to enhance image quality and compression over its predecessor, JPEG. Its support for transparency, layers, and metadata makes it a versatile choice in professional IT and imaging applications.
