When to add a watermark
- Mark internal documents “CONFIDENTIAL” so readers handle them with care
- Label quotes and proposals sent to clients as “SAMPLE” or “FOR REVIEW”
- Mark work in progress as “DRAFT” to tell it apart from the final version
- Add “DO NOT COPY” to handouts to make your wishes clear
- Put your name on portfolio or sample documents
Settings you can choose
Layout
“One in the center” places a large watermark in the middle of each page. “Tiled across the page” repeats a smaller watermark over the whole page, so it’s still visible even if part of the page is cropped.
Angle, size and color
Choose diagonal or horizontal, small, medium or large, and gray, red or blue. Typefaces are sans-serif (Gothic) or serif (Mincho), both with Japanese support.
Opacity
Adjust from 10% to 60%. Around 20–30% keeps the main text easy to read.
Check the preview before saving
Every change updates the page 1 preview immediately, so you can check that the watermark doesn’t overpower the text before saving. After saving, you can preview the whole PDF.
Things to know about watermarks
Text watermarks are added to every page as real (vector) text, so they stay sharp at any zoom. You can also use a logo image. Your original text and images stay as they are, and text can still be selected and searched.
A watermark signals how a document should be handled. It could be removed with PDF editing software, so consider adding a password to important documents as well.

Your PDF is never uploaded
Your PDF isn’t uploaded to a server; the watermark is added in your browser. Confidential documents are never sent anywhere.
