Stamp every page in seconds
This PDF watermark tool lays your text — CONFIDENTIAL, DRAFT, DO NOT COPY, a copyright notice — across every page of a document, centered and, if you like, angled corner-to-corner. Size and opacity sliders let you pick anything from a subtle brand mark to an unmissable stamp, and the whole job runs in your browser.
Why watermark at all?
A watermark states a document's status and ownership at a glance: reviewers can't mistake a DRAFT for a final, recipients are reminded a file is confidential, and shared samples carry your name wherever they're forwarded. It's labeling and deterrence — pair it with sensible distribution controls for anything truly sensitive.
Private, like every Toolerax PDF tool
Contracts and drafts are exactly the files you shouldn't upload to random servers. Here the PDF is parsed, stamped and saved locally with in-browser processing — it never leaves your device. Complete the workflow with page numbers, the PDF merger or the splitter.
Frequently Asked Questions
How do I add a watermark to a PDF?
Upload the PDF, type the watermark text (like CONFIDENTIAL or DRAFT), set the size and opacity, choose diagonal or horizontal, and download. The text is stamped across every page.
What opacity should a watermark use?
15–25% works for most documents — clearly visible without obscuring the content. Go higher for strong deterrents on sensitive drafts, lower for subtle branding.
Does the watermark go on every page?
Yes — it's centered on each page automatically, sized and angled the same throughout the document.
Can the watermark be removed later?
It becomes part of each page's content, so casual removal is hard — but no watermark is tamper-proof against determined editing. Treat it as labeling and deterrence, not security. For confidentiality, also control who receives the file.
Will this work on scanned PDFs?
Yes. The watermark is drawn as a layer on top of whatever the page contains — text, vector graphics or scanned images.
Is my document uploaded?
No — the PDF is processed entirely in your browser and never sent to a server.
