How to watermark a PDF

Add diagonal or straight text watermarks on every page for drafts, confidential labels, or branding.

Use this page as a full workflow guide: follow the steps below, then read the tips and FAQs before you start so you know what stays private, what limits apply, and how to get a reliable result on the first try.

How it works

  1. 1Upload your PDF.
  2. 2Enter watermark text and adjust size, opacity, angle, and color.
  3. 3Apply the watermark to all pages.
  4. 4Download the stamped PDF.

Tips for better results

  • Keep a copy of your original file — exports and compressions can permanently reduce quality or change layout.
  • Prefer a modern desktop browser for large files; phones work for smaller jobs but can run out of memory.
  • If a step fails, reload the page and try a smaller file or a simpler setting before retrying.

Frequently asked questions

Can I use an image logo?

This version supports text watermarks. Image stamps are planned next.

Will it cover content?

Yes by design. Lower opacity keeps content readable underneath.

Private?

Yes. Stamping runs locally with pdf-lib.

Can I watermark one page only?

Currently all pages. Use Split/Organize if you need a single-page file first.

Is my file uploaded to ToolJee for this tool?

Conversion and editing for PDF, image, video, and QR tools run in your browser. Optional File Share and Business cloud save only store what you explicitly choose to save or share.

Do I need an account?

Most tools work without signing in. File Share uploads and Business cloud save require an account.

Why add how-to text on a tool page?

So you can complete the job with clear expectations — privacy, limits, and common mistakes — even before you click the first button.
