2. Choose watermark type — Select Text Watermark to type custom text, or Image Watermark to upload a logo or image.

6. Click "Apply Watermark & Download" — The tool processes every page and downloads the watermarked PDF automatically.

Two Watermark Types

T Text Watermark

Type any text — "CONFIDENTIAL", "DRAFT", "DO NOT COPY", your company name, or a copyright notice. Choose from five fonts (Arial, Georgia, Courier New, Times New Roman, Verdana), set the color, and adjust the font size from 20px to 160px. The diagonal diagonal orientation is set by default for a classic watermark look, but you can rotate freely from -90° to +90°.

🖼 Image Watermark

Upload any image — your company logo, a stamp graphic, or a signature scan. PNG with a transparent background gives the cleanest result since only the logo appears on the page without a white box. Control the watermark size as a percentage of the page width and tile it across the entire page if needed.

Full Customization Controls

💧 Opacity

Set transparency from 5% (barely visible) to 100% (fully opaque). A typical watermark uses 20–30% opacity so the underlying content remains clearly readable while the watermark is unmistakably present.

🔄 Rotation

Rotate the watermark from -90° to +90°. The classic diagonal angle (-35°) is set by default — widely recognized as the standard watermark style — but you can set it to 0° for horizontal text or any other angle.

📍 8 Position Options

Place the watermark at any of seven fixed positions (top-left, top-center, top-right, center, bottom-left, bottom-center, bottom-right) or select Tile mode to repeat the watermark in a grid pattern across the entire page for maximum coverage.

📄 Selective Page Watermarking

Apply the watermark to all pages at once or target specific pages using a range input (e.g. 1-3, 5, 8-10). Pages outside the range are passed through to the output unchanged.

Common Use Cases

🔒 Marking Confidential Documents

Stamp legal contracts, financial reports, and internal policies with "CONFIDENTIAL" or "RESTRICTED" before distributing them to ensure recipients are aware of the document's sensitivity.

📋 Labeling Drafts and Proofs

Add a "DRAFT" or "FOR REVIEW ONLY" watermark to documents still under revision so reviewers never mistake an unfinished version for the final approved document.

🏢 Branding Business Documents

Stamp your company logo onto proposals, reports, and deliverables before sending them to clients. A logo watermark reinforces brand identity and deters unauthorized reuse.

📸 Protecting Creative Work

Add a copyright notice or your name as a watermark to PDF portfolios, photography books, and design documents before sharing online — discouraging unauthorized reproduction.

🎓 Academic and Training Materials

Watermark course materials, lecture notes, and exam papers with "FOR STUDENT USE ONLY" or an institution logo to control distribution and protect intellectual property.
