How to add a watermark to a PDF
A watermark marks a document's status or ownership — DRAFT, CONFIDENTIAL, a company name — across every page. It signals intent and makes casual copying obvious.
Open Add WatermarkStep by step
- Open the Watermark tool and drop your PDF in.
- Type the text you want and adjust how it sits on the page.
- Download the watermarked PDF, stamped on every page.
Choosing the wording
Keep it short and unmistakable: DRAFT, CONFIDENTIAL, NOT FOR DISTRIBUTION, or a name. Long phrases get hard to read once they're laid over the content.
A faint, diagonal mark stays legible without burying the text underneath it.
A watermark is a deterrent, not a lock
Watermarking labels a document; it doesn't stop someone determined from removing it. For real restriction, add a password with the Protect PDF tool.
The two work well together: a CONFIDENTIAL stamp plus a password covers both the message and the access.
