Step by step
How to add a watermark to a PDF
A text watermark says something about a document before anyone reads it: DRAFT on a proposal that isn't final, CONFIDENTIAL on contracts and financials, PAID on settled invoices, SAMPLE on proofs you send a client before approval, or your company name across a portfolio so it stays credited as it travels. One stamp on every page communicates status and ownership without a single word of explanation.
Drop your PDF
Drag the document into the box above, or click to browse for it.
Type your watermark text
Something like CONFIDENTIAL, DRAFT or PAID — then set the size, opacity and angle to taste. Light and diagonal is the classic professional look; strong and horizontal reads like a stamp.
Click “Run Watermark PDF”
The text is stamped onto every page instantly, right in your browser. The document never leaves your device.
Download the watermarked PDF
The watermark is now part of the page content — it shows in every PDF reader and on every printout. No watermark-of-the-watermark, nothing else added.
Why PDFication
Why use PDFication to watermark PDF files?
Private documents stay private
Watermarking usually happens to the most sensitive files — contracts, financials, unpublished work. This tool stamps them entirely in your browser; nothing is uploaded anywhere.
No watermark on your watermark
Plenty of free tools stamp their own brand onto your output alongside yours. This one doesn't — the only text on your pages is the text you typed.
Full control, instantly
Choose the exact wording, size, transparency and angle, and see the result immediately. A faint diagonal or a bold horizontal stamp — both are seconds away.
Every page, consistently
The watermark is applied to all pages at once, in the same position and style — something word processors make you place by hand, page by page.
Choosing the right tool
Watermark settings, explained
The difference between a professional-looking watermark and an ugly one is three small choices:
Angle — diagonal or horizontal
Diagonal (45°) is the classic: unmissable but easy to read around. Horizontal works like a formal stamp at the page's heart — DRAFT across a cover page, for example.
Opacity — subtle or loud
Very light (0.15–0.3) keeps the text fully readable underneath — right for CONFIDENTIAL on a contract. Strong (0.5+) makes the document clearly unfinished — right for proofs and drafts.
Text — short and bold wins
One or two words in capitals read best: DRAFT, CONFIDENTIAL, SAMPLE, PAID. Long sentences turn to clutter, especially on smaller pages.
What about logos and images?
This tool stamps text only — image watermarks aren't supported yet. For ownership marking, your name or company name in a clean font does the same job.
The safe default for professional documents: CONFIDENTIAL, Very light opacity, Diagonal. Stamp first, then [compress](compress-pdf) if you're emailing it — or [merge](merge-pdf) several marked files into one.

FAQ
Frequently asked questions
▸Can I add a logo or image watermark?
Not yet — this tool applies text watermarks only. For ownership marking, a clean text stamp (your name, brand or NOT FOR DISTRIBUTION) covers most needs. Image watermarking is on the roadmap.
▸Will the watermark appear on every page?
Yes — the same text, in the same position, style and transparency, is stamped on all pages of the document in one run.
▸Will the watermark show when the PDF is printed?
Yes. The watermark becomes part of the page content itself, so it prints exactly as it looks on screen — that's what makes it effective for DRAFT and CONFIDENTIAL documents.
▸Can I remove a watermark from a PDF?
This toolbox doesn't remove watermarks — and think twice before removing one you didn't add: watermarks usually mark ownership, drafts or confidentiality, and stripping them can violate the document's terms or someone's copyright. If you added a watermark yourself and still have the original file, simply re-export from the original.
▸What text and symbols can I use?
Letters, numbers and standard punctuation — in any combination and capitalization you like. Emoji and some special symbols aren't supported by the built-in fonts and will be rejected; if you need a symbol-free alternative, spelled-out words like CONFIDENTIAL work everywhere.
▸Does watermarking change the rest of my document?
No. Only the stamp is added — your text, images, links and form fields are untouched, and the original file on your disk is never modified. You receive a new, watermarked copy.
