CCITT Group 3 Fax Image (.g3)

The G3 file extension refers to the CCITT Group 3 Fax Image, a standardized format developed by the Consultative Committee for International Telegraphy and Telephony (CCITT), now known as ITU-T. This format was created to efficiently compress black-and-white fax documents for transmission over telephone lines. It employs a method called Modified Huffman Coding for data compression, enabling reduced transmission time and bandwidth usage. G3 was widely adopted in the 1980s and 1990s as the primary standard for fax transmissions, ensuring compatibility across different fax machines and systems.

JPEG 2000 Compound Image File Format (.jpm)

The JPM file extension, integral to the JPEG 2000 image coding system, is tailored for document imaging using the Mixed Raster Content model. It supports multi-page, layered images and provides superior compression and image quality through wavelet-based methods. Despite its technical benefits, including support for both lossy and lossless compression, its adoption is limited due to complexity and the requirement for specialized software.
