## When to use

## How it works

- Upload your source PDF file to the tool.
- Enter your username and select the desired policy label and timestamp format.
- Adjust visual settings like opacity, rotation, font size, and color to match your branding.

- Applying 'Internal Use Only' watermarks to company policy documents to prevent external distribution.
- Stamping draft contracts with a username and timestamp to track document versions during negotiations.

## Frequently asked questions

You can choose between ISO 8601 format or your system's local time format.
