Questions
Does a watermark prevent copying?
No. A watermark is a visible mark, not a guarantee against copying or editing. Choose a position and appearance that communicate your message without obscuring the document.
Can a watermark remove information underneath it?
No. Covering content with text or a picture is not permanent removal. Use Redact PDF for confidential information, and check the finished redacted copy before sharing.
Can I watermark only selected pages?
Yes. Open Choose pages, then select page thumbnails or enter a range and click Select.
Can I put a watermark only on odd or even pages?
Yes. Open Choose pages and use the Odd or Even shortcut.
