Convert DJVU to JNG

The DjVu file extension, developed by AT&T Labs in 1996, stands for "Digital Journal Viewer". It is designed to store scanned documents and combine text, line drawings, and images with high compression efficiency. DjVu files are widely used for digitizing books, magazines, and historical documents due to their ability to produce smaller file sizes compared to PDF, JPEG, and TIFF formats. This format employs advanced technologies like image layer separation, progressive loading, and arithmetic coding, making it ideal for web distribution and archival purposes.

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.
