JFI to SIX conversion is the process of transforming an image stored in the JFI (JPEG-Frame Interchange) format into the SIX (Spatial Indexed eXchange) format. This conversion repackages pixel data, metadata, and index structures so the output image is optimized for SIX's tiling, spatial indexing, and progressive streaming features.
