SFW to G3 conversion is the process of transforming image files in the SFW (Styled Flexible Web) format into the G3 (Grayscale Group 3) image format. This conversion adapts SFW's flexible web-optimized, layered or metadata-rich images into the compact, monochrome-oriented G3 format commonly used for scanned documents and fax-compatible imagery.
