Digital Journal Viewer (.djvu)

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 DjVu files are widely used for digitizing books, magazines, and historical documents due to their ability to produce smaller file sizes compared to PDF, JPEG, and TIFF formats.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.

JPEG 2000 Code Stream Syntax (.j2k)

The J2K file extension stands for JPEG 2000 Code Stream Syntax, a part of the JPEG 2000 standard developed by the Joint Photographic Experts Group (JPEG). Introduced in 2000, JPEG 2000 offers superior image compression and quality compared to the original JPEG format. The J2K codestream is highly flexible, supporting both lossy and lossless compression, and allows for scalable decoding, which means images can be efficiently accessed at various resolutions and quality levels. This makes J2K ideal for applications requiring high-quality image storage and transmission, such as medical imaging, digital cinema, and satellite imagery.
