JNX to RGF conversion is the process of transforming map or raster image data stored in the JNX format into the RGF image format. This conversion rewraps the source tiles, tileset metadata, and compression into RGF containers so the images can be used by applications that require RGF files.

Keep individual JNX files under 250 MB for fastest processing; larger files (up to service limits) are supported but take longer.
To preserve visual fidelity, choose lossless RGF or high-quality RGF settings, and avoid repeated re-encoding cycles.
For many files, use batch conversion to maintain consistent settings; process in groups of 10–50 to balance speed and memory usage.
