Adding text to PDF pages
A text watermark is drawn on every page with the selected opacity. Existing page content remains in the document.
Output behavior and limits
A watermark does not encrypt a PDF, establish ownership or prevent editing and copying. Long text can fit poorly on small pages.
Use a short label such as DRAFT, then inspect dense text and diagrams in the downloaded PDF to ensure they remain readable.
