How to add a watermark
Upload your PDF, type the watermark text you want, and adjust the opacity and size to taste. The text is stamped diagonally across the center of every page.
Will this affect the original text?
No — the watermark is added as a new layer on top of the page. The original content underneath is untouched and remains fully selectable.
