Add Watermark to PDF lets you place a text label, logo, stamp or other image over your PDF pages. Control the watermark size, opacity, rotation and position, then apply it to every page or only selected pages.
Common use cases
Add ownership information
Place a company or project label on distributed PDF copies.
Create controlled derivatives
Generate a marked version while retaining an untouched original PDF.
How it works
1
The browser opens the PDF and prepares the watermark text or graphic settings.
2
The watermark is placed onto the selected pages using the chosen position, opacity and rotation.
3
A new PDF is generated with the watermark embedded into its page content.
Privacy & file handling
Watermarking is processed locally
The supported PDF watermark workflow modifies the document in the browser rather than requiring the source PDF to be uploaded to Zavilo.
Limitations and important notes
- A watermark discourages casual reuse but is not a complete document-rights-management system.
- Opaque or large watermarks can cover important page content.
- Some PDF editors may still be able to alter or remove watermark content from the resulting file.
Watermark vs password protection
| Feature | Primary purpose | Use when |
|---|---|---|
| PDF Watermark | Visible labeling or ownership notice | Recipients should see a mark on the pages |
| Protect PDF | Restrict opening or certain access | You need password-based document protection |
