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