PDF Watermark stamps text onto document pages to mark status, source, or ownership. Set the text, color, opacity, rotation, and position, then download a marked PDF copy.

Input: An unlocked PDF and text watermark settings.
Output: A new PDF with watermarks on its pages.
Know before use: A watermark is not cryptographic protection and can be removed with a PDF editor; existing digital signatures may also become invalid after modification.
