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 PNM (Portable Anymap) file extension, developed by Jef Poskanzer in the 1980s, stands for Portable Any Map. It is an uncompressed raster graphics format designed for portable image storage and exchange, encompassing three sub-formats: PBM (Portable Bitmap), PGM (Portable Graymap), and PPM (Portable Pixmap). PNM files store image data in plain text or binary format, ensuring easy usage across different platforms and applications. This format is widely supported by various image editing software and is valued for its simplicity and lossless compression.
