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