Joint Photographic Experts Group (.jpg)

The JPEG (Joint Photographic Experts Group) file extension, abbreviated as JPG, is a widely used format for digital images. Originating from a standard established by the Joint Photographic Experts Group in 1992, it became the go-to choice for compressing photographic images due to its balance of compression and image quality. JPG files are particularly effective for web use, digital photography, and archival storage where color fidelity and small file size are paramount. This format's lossy compression reduces file size by discarding non-essential data, making it efficient for online image sharing and storage.

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.
