SFW to RB conversion is the process of transforming images stored in the SFW (Scalable Frame Work) format into the RB (Rendered Bitmap) format. This conversion re-encodes SFW's scalable, layer-aware data into a flattened, pixel-based RB file suitable for pixel-accurate display, legacy compatibility, or raster-only workflows.
