How to Secure Your PDF in 3 Easy Steps
Customizing your documents takes less than a minute. Follow these steps to apply your unique branding.
1. Select PDF

Advanced Customization Features
Our toolkit provides granular settings that allow you to match your company’s branding or legal requirements exactly.
Dynamic 9-Point Alignment
Precisely anchor your watermark to the center, top-left, or any corner using the interactive position grid for consistent placement across all pages.
Vector & High-Res Image Support
Upload PNGs with transparency or crisp SVGs. Our engine maintains image quality even when scaling logos to fill the entire page.
Real-Time Visual Feedback
Every adjustment to opacity, rotation, and size is reflected instantly on the document preview before you commit to the download.
Pattern & Tile Mode
Switch from a single stamp to a repeating pattern. Tiling creates a security mesh across the text, making unauthorized content removal nearly impossible.
Full Rotation Control
Dial in the exact angle—from subtle horizontal text to the industry-standard -45° diagonal 'Confidential' stamp.
Client-Side Processing
We use WebAssembly to handle the heavy lifting inside your browser window. This ensures your documents are never transmitted to our infrastructure.
Quick Style Recipes
The "Confidential" Stamp

Discreet Branding
Upload your Logo, use the Bottom-Right grid position, and set Scale to 15%.
Anti-Copy Mesh
Toggle Tile Watermark on with a 10% Opacity to protect the entire page content.
Text vs. Image: Choosing Your Style
Text Labels
Perfect for status updates like DRAFT, VOID, or CONFIDENTIAL. Easily change font size and rotation to fit your layout.
Brand Logos
Ideal for business proposals and creative work. Use your official logo to ensure your brand is recognized wherever the file is shared.
Mastering Placement & Visibility
Achieving the perfect balance between document security and readability depends on how you configure these three key settings:
Use the 9-point grid to anchor your mark. Center placement is best for high-security "Draft" stamps, while corner anchors provide a non-intrusive "Letterhead" feel for corporate branding.
Enable Tile Watermark for sensitive proofs. This creates a repeating mesh across the entire page, ensuring that even small screenshots or cropped sections remain clearly identified.
We recommend an Opacity of 10%–25%. This range ensures your watermark survives printing and scanning while keeping the underlying text 100% legible for the reader.
A -45° angle is the global standard for "Confidential" or "Draft" labels. It crosses both text and white space, making the mark visible regardless of the document's layout.
