Lays a diagonal text watermark - DRAFT, CONFIDENTIAL, a client's name - across the middle of each page, with control over how faint, how large and at what angle. The watermark is real PDF text drawn under your control, not a picture pasted on top, so the file stays small and the pages stay sharp.
Frequently asked questions
Common questions about the watermark pdf.
What opacity should I use?+
Around 15% is the usual choice: clearly visible, but the document underneath still reads comfortably. Push it higher only when the watermark matters more than the text.
Can the watermark be removed by whoever receives it?+
Yes, by anyone with a PDF editor - it is drawn into the page, not locked to it. A watermark marks a document's status; it does not secure it.
Can I use my logo instead of text?+
Not in this tool - it stamps text only. For an image watermark, place the logo in your source document before exporting to PDF.
