Drop a PDF, type "CONFIDENTIAL" (or any other text), keep position on Diagonal, adjust opacity and color, then Apply & Download. The watermark is stamped on every page as real PDF text — selectable, vector-sharp at every zoom level — not a rasterised overlay.
usageEight positions plus Diagonal: Top-Left, Top-Center, Top-Right, Center, Bottom-Left, Bottom-Center, Bottom-Right (all upright) and Diagonal (rotated, large, centered). Diagonal is the classic anti-copy watermark; corner positions are good for branding or version stamps.
featuresYes — the watermark is part of the page content, not viewer-side decoration. It prints, exports, and screenshots along with the document. Bypassing it requires re-creating the PDF from scratch.
featuresText — we render with the embedded Helvetica Bold standard font using pdf-lib's drawText, so it scales infinitely without pixelation and adds minimal bytes to the file. For image/logo watermarks on PDFs, place your logo on the first page of a blank PDF then merge it on top.
technicalUse the opacity slider — 20-30% is the typical sweet spot for "visible but unobtrusive". The colour also matters: light grey at 30% reads as a soft watermark on white pages, while red or orange grabs attention even at lower opacity.
tipsCurrently all-or-nothing — the watermark applies to every page in the PDF. To watermark a subset, split the PDF with our Split PDF tool, watermark only the parts you want, then merge them back together.
featuresYes — pdf-lib runs in your browser. The watermarked PDF is saved client-side without ever uploading the source. Safe for contracts, draft proposals and confidential client deliverables.
privacyFree, unlimited use, no watermark on the watermark (we don't add our own branding). All settings save in your browser session for quick repeat use.
pricingHow Watermark PDF helps you get it done
Real problems it solves every day — for businesses, creators, and everyday tasks. Find the use case that fits you and start in seconds.
Stamp CONFIDENTIAL on Internal Documents
Internal strategy decks, M&A diligence and board materials should be clearly marked confidential. Stamp every page diagonally before circulating to prevent leaks if a file escapes the intended audience.
Mark DRAFT on Work-in-Progress Contracts
A "DRAFT" watermark across every page prevents an early version from being mistaken for a signed contract. Remove the watermark with a new merge once the final is approved.
Client-Specific Watermarks
Add a per-client watermark (e.g. client name + date) to deliverables so if the file is shared outside the engagement, you know whose copy leaked. Subtle deterrent, strong tracking.
Educational Material Branding
Online course providers stamp course PDFs with the student name and enrolment ID to discourage re-sharing. Personalised watermarks beat blanket DRM for most paid-content platforms.
Photographer & Designer Proofs
When sending PDF portfolios to potential clients, a "PROOF" watermark prevents unlicensed use before payment. Remove on invoice clearance.
Government Form Versioning
Mark template versions clearly (e.g. "DRAFT v3 - 2026") so reviewers know exactly which version is on their desk. Critical when multiple stakeholders are reviewing the same form across weeks.
