Understand the task
Choose wording that accurately describes the document's status. Use readable contrast and place the mark where it will not cover signatures, tables, diagrams or important text. A watermark is a visible reminder, not encryption or DRM.
Important details to check
PDFs may mix portrait and landscape pages or different sizes. Review every page type because one position may not work for all pages. Keep the original file and remember that editing a signed PDF can affect signature validity.
Recommended workflow
Make a copy, enter the watermark wording, choose a suitable position and style, export and inspect every page at normal reading size.
Step-by-step checklist
- Read the instructions for the file, assignment or service you are working with.
- Keep an unchanged copy of important source material.
- Use the related tool and review the result instead of assuming every conversion is perfect.
- Check the output in the application or context where it will actually be used.
