How to add a watermark to a PDF
A watermark is text or a mark layered over the pages of a document, such as “CONFIDENTIAL”, “DRAFT” or a company name. It communicates the status or ownership of a file at a glance and discourages unauthorised reuse, because the mark appears on every page and is awkward to remove from a distributed copy.
This tool stamps your chosen text across each page and returns the watermarked PDF.
The strength of a watermark over a header or a covering note is that it cannot be cropped out of a photocopy or lost when a single page is forwarded: the status travels on the page itself. That is why courts, agencies and studios have marked working documents this way for decades.
Step by step
- Open the Watermark PDF tool and upload your document.
- Type the text you want to appear, such as CONFIDENTIAL or your company name.
- Press Process to apply the watermark to every page.
- Review how the mark sits over your content.
- Download the watermarked PDF.

Why use this tool
Watermarks protect both your work and your message. Marking a document as a draft prevents an unfinished version from being mistaken for the final one, while a confidentiality stamp reminds readers that the contents are not for circulation — a simple, visible deterrent that travels with the file wherever it goes.
Branding documents with your name or logo also reinforces ownership and looks professional when sharing proposals or sample work.
Common uses cover the whole life of a document: stamping “DRAFT” on a circulating proposal, “SAMPLE” or “SPECIMEN” on a template, “PAID” on a settled invoice, or a studio name across preview images sent to a client before payment. Because the mark sits on every page, a single leaked sheet still carries the warning — something a footer line or a covering email cannot guarantee.
Watermarks pair naturally with the security tools: stamp "CONFIDENTIAL" so every reader sees the status, then add a password so only the intended readers become readers at all. For samples and previews the watermark works alone — the file is meant to circulate, just not to be used as final — while on internal drafts a simple "DRAFT" saves the embarrassment of an old version being executed as the real one.
Is it safe? Your privacy
Your file is uploaded only to apply the watermark and is deleted automatically from our servers within minutes. The document is never stored, read or shared.
Troubleshooting: common problems and fixes
- The watermark dominates the page. — Use a shorter word or an acronym — the longer the text, the larger the area it covers. A concise mark like DRAFT communicates just as clearly while covering less of the content.
- I watermarked the wrong version. — The mark cannot be peeled off afterwards, but your original is untouched: fix the source file and stamp it again. Always keep an unwatermarked master.
- I need different marks for different recipients. — Run the tool once per recipient from the same clean master — for example "COPY FOR SMITH & CO". Personalised marks make any leaked copy traceable to its recipient.
- The file is rejected as password-protected. — Remove the protection first with Unlock PDF, stamp the watermark, then protect the result again.
Frequently asked questions
Can I watermark only some pages?
The watermark is applied across the document so the marking is consistent on every page.
Does the watermark hide my text?
It is layered over the pages so your content remains readable beneath it.
Is a watermark the same as protection?
No. A watermark is a visible deterrent, not encryption. To stop a file being opened or copied at all, use Protect PDF to add a password as well.
Can the watermark be removed later?
It is merged into the page content, so it cannot simply be toggled off. Keep an unwatermarked master copy if you will need a clean version later.
Will it show when the document is printed?
Yes. Because the mark is part of the page, it appears identically on screen and on paper wherever the PDF is opened.
Can I use my company name or a label?
Yes — type any text such as your company name, “CONFIDENTIAL” or a project code, and it is stamped across each page.
Text or image watermark — what does this tool add?
A text watermark: you type the wording and it is stamped across each page. For a graphic logo, place it with the image stamp in Edit PDF instead.
Does a watermark protect me legally?
It is a visible notice, not a legal mechanism: it deters misuse and shows intent, which supports a claim, but it does not replace contracts, licences or registration where those are required.
