No, converting KAR to S3M does not cause additional quality loss — S3M uses lossless compression. However, any artifacts already present in the original KAR file will persist in the S3M output.
S3M files are typically 2-5x larger than equivalent KAR files because S3M preserves all pixel data. This is expected and necessary for lossless quality.
