Convert JPG to G4

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.

The G4 file extension, standing for CCITT Group 4 Fax Image, is a specialized format used primarily for storing black-and-white facsimile (fax) images. Its origins trace back to the Consultative Committee for International Telegraphy and Telephony (CCITT), now known as the ITU-T, which developed the Group 4 standard in the 1980s to improve fax transmission efficiency over digital networks. This format employs a high compression ratio to reduce file size while maintaining image quality, making it ideal for archiving documents and transmitting faxes in professional and business environments.
