About this tool
Use Watermark PDF with confidence.
A watermark adds visible context such as Draft, Confidential or a recipient name directly to chosen PDF pages. UsefulGrid places the text into a new PDF copy while leaving the source file unchanged.
You can control the text, page range, position, size, color, opacity and rotation. The first-page preview is a placement guide; always open the downloaded PDF to review every marked page at normal zoom.
Common uses
Make an unfinished document unmistakable before circulating it for review.
Add a visible handling reminder across all pages or only a sensitive section.
Place a recipient, project or status label on a PDF before sharing it.
Practical tips
Use enough contrast to remain visible without making the underlying text difficult to read.
A position that works on a sparse cover may overlap important content on later pages.
A visible watermark discourages misuse and adds context, but it does not encrypt the file or prevent editing.
Questions about Watermark PDF
Does adding a watermark flatten every page?
No. The tool adds text to the PDF pages instead of converting the entire document into page images.
Can I watermark only certain pages?
Yes. Enter individual pages or comma-separated ranges, such as 1-3, 7 and 10-12.
Will digital signatures remain valid?
Usually not. Changing a signed PDF can invalidate its signatures. Keep the signed original and verify the downloaded copy before using it.
