Common questions and quick fixes
Can I add a logo watermark to my PDF?
This tool adds text watermarks only. It does not accept a logo or image as a watermark.
Why does my watermark text show an error?
Use basic Latin letters, numbers or punctuation, with no more than 70 characters. Shorter text also fits small pages more reliably.
Can I watermark only selected pages?
The current setting applies the watermark to every page. It does not include a page-range selector.
Does a watermark prevent copying or editing?
No. A watermark adds a visible label. It does not encrypt the PDF or guarantee that someone cannot copy or change its content.
Helpful tip: Choose a short watermark and check that it does not hide important text.
