FAQ
Can I use image watermarks?
This tool adds text watermarks only. For logo watermarks, use a desktop editor or design tool.
Does watermarking prevent copying?
Watermarks deter casual sharing but do not encrypt or DRM-protect the PDF.
Will watermarks print?
Yes. Watermarks are embedded in the page content and appear when printed.
Can I remove a watermark later?
This tool adds watermarks permanently. Keep an unwatermarked original if you need both versions.
Is this PDF watermark tool free?
Yes. Unlimited watermarking with no signup.
