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.
Watermark your PDF now
Add a CONFIDENTIAL stamp, a DRAFT label, or your logo to every page — processed locally, never sent to a server.
Open the PDF watermark tool →Step-by-step: add a watermark to every page
- Open the PDF watermark tool.
- Drag in your PDF, or tap to browse and select it.
- 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).
- Adjust the opacity so the stamp is visible but the page underneath stays readable — somewhere around 15–30% is a good starting point.
- Set the position and angle — a diagonal stamp across the center, or a corner/header placement for a subtler mark.
- 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.
