How to Add a Watermark to a PDF

Apply text or logo stamps in 3 simple steps.

1

Upload Your PDF File

Select your draft manuscript, confidential report, or invoice and drop it into the watermark tool above.

2

Customize Text or Logo Stamp

Enter custom text (e.g., 'CONFIDENTIAL', 'DRAFT') or upload your logo. Adjust opacity, rotation, and font style.

3

Download Watermarked PDF

Apply the watermark across all pages or selected ranges and download your branded document immediately.

The Best PDF Watermarking Tool

Full opacity adjustments, custom 45-degree diagonal rotation angles, PNG logo support, and multi-page range controls.

Custom Text & Logo Watermarks

Apply standard stamps ('CONFIDENTIAL', 'SAMPLE', 'DO NOT COPY') or upload high-res transparent PNG logos.

Full Opacity & Angle Control

Dial in transparency levels from 10% to 100% and rotate stamps diagonally (45°) or horizontally.

Multi-Page Selective Stamping

Apply stamps to every page, only even/odd pages, or specific customized page index ranges.

100% Free with No Accounts

Watermark unlimited business documents with zero monthly subscriptions or limitations.

Private & Auto-Deleted

All transmissions are encrypted via SSL/TLS. Files are processed securely and deleted immediately after your session.

Cross-Platform Access

Add watermarks directly in your web browser on iPad, iPhone, Android, macOS, Windows, and Linux.

Transparency Matrix & Vector Stamp Geometry

PDF Maya blends text stamps and image logos directly into the background without rasterizing or modifying underlying text.

Calibrated Alpha Transparency

Adjust opacity levels with pinpoint accuracy so watermarks clearly declare copyright while keeping document body text legible.

True Vector Typography Rotation

Diagonal 45-degree text stamps are rendered as vector typography matrices, guaranteeing smooth edges on retina displays and printouts.

Lossless PNG Logo Blending

High-resolution company logos and seal artwork blend seamlessly over page elements with full transparent background support.

Selective Page Range Stamping

Choose whether to watermark every single page, skip the cover page, or apply stamps exclusively to even or odd pages.

Practical PDF Watermarking Use Cases

Protect copyright, enforce non-disclosure agreements, and brand corporate files.

Draft & Revision Notices

Mark work-in-progress legal briefs, architectural blueprints, and financial projections as 'DRAFT' or 'PRELIMINARY'.

Confidentiality & NDA Enforcement

Stamp sensitive executive compensation models and merger proposals with large diagonal 'STRICTLY CONFIDENTIAL' labels.

Brand Logo Stamping

Embed company logos, certificate seals, and copyright notices into whitepapers and training guides.

Client Proofing & Sample Reviews

Prevent unauthorized usage of photography portfolios, graphic designs, and ebooks before final invoice payment.
