Watermark PDF — frequently asked questions
What text can I use as a watermark?
Anything you type — common choices are CONFIDENTIAL, DRAFT, COPY, or your name or company. It's stamped diagonally across each page.
Does the watermark hide my content?
No. It's applied as a light diagonal overlay so your document stays readable while the watermark is clearly visible.
Can the watermark be removed?
It's merged into the pages, so it can't be toggled off in a normal viewer. Keep your un-watermarked original if you'll need a clean copy.
Is it added to every page?
Yes. The watermark is stamped on all pages of the PDF in one go.
