Frequently asked questions

Can I control how visible the watermark is?
Yes — an opacity slider lets you go from a faint background stamp to a bold, fully opaque label.
Is the watermark removable by whoever receives the file?
It's drawn directly onto the page content, so it's not a toggleable layer — removing it would require manually editing the PDF.
