Convert G4 to EPI

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.

The EPI file extension stands for Encapsulated PostScript Interchange, a format developed by Adobe in the late 1980s. It facilitates the integration of vector graphics and text into documents for high-resolution printing. EPI files, a variant of EPS, are primarily used in graphic design and desktop publishing to ensure consistent and scalable image quality. This format employs Adobe's PostScript language to describe the appearance of a single page, making it ideal for embedding illustrations in various documents.
