Frequently Asked Questions
Is the watermark applied to every page?
Yes, the text watermark you configure will be stamped diagonally across the center of every single page in the document.
Can the watermark be easily removed?

Is my confidential PDF safe?
Absolutely. Our watermark tool uses the pdf-lib library to process your file entirely within your browser. The file is never uploaded to any server.
