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