How to Add a Watermark to a PDF

Stamp CONFIDENTIAL, DRAFT, or your logo onto every page — free, private, and processed entirely in your browser.

A watermark is the quickest way to tell everyone how a document should be treated. A pale CONFIDENTIAL stamp across each page signals that a file isn't for sharing; a DRAFT label stops an unfinished version being mistaken for the final one; and a faint company logo marks a proposal or report as clearly yours. The best part is that you don't need Acrobat or any paid software to do it — you can stamp a text or image watermark onto every page of a PDF right in your browser, and because the work happens on your own device, the file is never uploaded anywhere.

Step-by-step: add a watermark to every page

  1. Open the PDF watermark tool.
  2. Drag in your PDF, or tap to browse and select it.
  3. Choose a text watermark — type a label such as CONFIDENTIAL, DRAFT, or your company name — or switch to an image watermark and upload a logo (a transparent PNG looks cleanest).
  4. Adjust the opacity so the stamp is visible but the page underneath stays readable — somewhere around 15–30% is a good starting point.
  5. Set the position and angle — a diagonal stamp across the center, or a corner/header placement for a subtler mark.
  6. Preview the result, confirm it lands on every page, and download your watermarked PDF.

When a watermark is the right tool

  • CONFIDENTIAL / INTERNAL stamps on contracts, reports, and financials you're circulating internally.
  • DRAFT / NOT FINAL labels so reviewers never confuse a work-in-progress with the approved version.
  • Logo watermarks to brand proposals, portfolios, and pitch decks and discourage copying.
  • SAMPLE / SPECIMEN marks on templates and preview copies you share publicly.

Tips and common pitfalls

  • Don't crank the opacity too high. A solid stamp can make the underlying text hard to read; keep it light so the document stays usable.
  • Use a transparent PNG logo. A logo saved on a white box will paste an ugly rectangle over the page — a PNG with a see-through background blends in cleanly.
  • A watermark labels, it doesn't lock. It's a visual deterrent that survives printing and screenshots, but it doesn't remove or encrypt anything. If you need to make sensitive text truly disappear, use our redaction tool instead — note that redaction flattens the affected area to an image so the hidden text can't be recovered.
  • Keep the original. Watermark a copy so you can re-stamp the clean file later — for example when DRAFT becomes FINAL.
  • Want to lock the file down too? After stamping, you can password-protect the PDF for an extra layer of control.

Frequently Asked Questions

Does a watermark stop people from removing it?
A watermark is a strong visual deterrent, not a technical lock. It clearly marks a document as CONFIDENTIAL, DRAFT, or company-owned, and it survives printing and screenshots. Someone determined could still edit the source PDF, so for text you truly need gone, use redaction instead — a watermark's job is to label and discourage, not to encrypt.
Can I put my company logo on every page?
Yes. Choose an image watermark and upload a PNG logo — a transparent PNG works best so the page shows through around it. Set it to a low opacity and place it in a corner or tile it across the page, and it will be stamped onto every page of the document in one pass.
Will the watermark cover up my text?
Only as much as you want it to. Lowering the opacity to roughly 15–30% lets a diagonal stamp sit over the content while the underlying text stays perfectly readable. For a lighter touch, place it in a header, footer, or corner instead of across the center of the page.
Is it safe to watermark a confidential contract?
Yes. The watermark is applied entirely in your browser, so the PDF and your logo are never uploaded to a server. That makes it safe for contracts, financial statements, legal drafts, and anything else you can't risk sending to a third party.
Can I remove or change a watermark later?
Always keep your original, un-watermarked file. The tool produces a new stamped copy and leaves your source untouched, so if you need a different label — say, swapping DRAFT for FINAL — you simply re-watermark the clean original rather than trying to peel a stamp off the finished PDF.
