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.
