Add watermark
Add a text watermark across your pages.
A watermark labels a document at a glance — “DRAFT”, “CONFIDENTIAL”, or your company name — and discourages unauthorized reuse.
You control the text, size, rotation, color, and transparency so the watermark is visible without hiding the content underneath.
How to add a watermark to a PDF
- Choose the PDF you want to watermark.
- Enter the text and set size, angle, color, and opacity.
- Run the tool.
- Download the watermarked PDF.
Frequently asked questions
Will the watermark hide my text?
Not if you keep opacity low; the mark sits over the page semi-transparently.
Can I watermark every page?
Yes. The watermark is applied across the document in one run.
