Practical Use Cases
Draft circulation

Branding

Privacy and File Processing
Watermark PDF keeps its PDF, or PNG/JPG image for image watermark input in browser memory while the operation runs. The workflow creates PDF for local preview or download and does not send the entered values or selected file bytes to the GXA Toolbox application server.
Supported Inputs and Outputs
Input
- PNG/JPG image for image watermark
Output
How It Works
The PDF writer measures the chosen text or image watermark, calculates its page coordinates, opacity, scale, and rotation, and draws it onto each selected page.
Limitations and Important Notes
- Watermarks are visible marks, not access control.
- Embedded transparency and uncommon image formats may render differently.
- Editing a signed PDF may invalidate its digital signature.
Worked Example
Add a semi-transparent “REVIEW COPY” mark diagonally across every page while keeping the underlying text readable.
Helpful Tips
- Use moderate opacity so content remains legible.
- Use Protect PDF separately when access control is required.
