No, converting SITX to LBR does not cause additional quality loss — LBR uses lossless compression. However, any artifacts already present in the original SITX file will persist in the LBR output.
LBR files are typically 2-5x larger than equivalent SITX files because LBR preserves all pixel data. This is expected and necessary for lossless quality.
