Once converted to PDF, the layout will be "locked" — text, images, and formatting stay fixed exactly as they appear, which is ideal for sharing a final version that shouldn't change. Your original UDF file has no embedded images, so the PDF output will contain formatted text only. UDF organizes content into defined fields rather than free-form text, which is common in enterprise and legal document systems.
