It is also handy for marking a proposal as a draft or adding a company logo.

Text or logo, your choice

Add a text watermark or a logo image wherever you want. The original is left as-is and a new file is created.

Place it where you want

For example, put a large 'Confidential' in the center of the page, or a small logo in the bottom-right corner.
