When it comes in handy
For example, it helps when you need to stamp 'Confidential' across a quote before sending it to a partner.
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.
