Before you convert
The watermark is a visual layer; determined users can still remove it with editing tools.
Stamp a visible label across your PDF
Watermark PDF overlays text — like “DRAFT” or “CONFIDENTIAL” — on every page. Control the message, opacity, angle, and placement.
A watermark is a deterrent, not a lock: it marks documents for recipients but can be removed with editing tools. Combine it with other controls when content is truly sensitive.
Useful situations
- Mark review copies as DRAFT before circulating.
- Label confidential documents for internal distribution.
- Brand exported reports with a company name.
How to use Watermark PDF
- Select a PDF within the size limit.
- Enter the watermark text and set position, opacity, and angle.
- Convert and check that the stamp is visible but readable over content.
What to expect
- The watermark sits above page content — high opacity can obscure text.
- It is a visual layer that determined editors can strip.
- Every page receives the same stamp; per-page watermarks are not supported.
Frequently asked questions
Can a watermark be removed from the PDF?
Yes — it is an overlay, not encryption. It discourages casual misuse but is not a security barrier.
How do I make the watermark subtle?
Lower the opacity toward 0.1–0.2 and use a diagonal placement — it stays visible without blocking the underlying text.
Can I watermark only certain pages?
Not currently — the stamp applies to every page. Split the PDF first if you need a partial watermark, then merge the parts.
