Privacy

This tool runs entirely in your browser. Your files are never uploaded to a server, never stored by PDFZova, and never shared with anyone. Closing the tab discards them. The only exception is if a future tool is explicitly labelled as server-processed — this tool is not one of those.

Frequently asked questions

Can the watermark be removed later?

Not from the downloaded file — it is drawn into the page. Keep the original PDF if you need a clean version.

About Add Watermark

Mark drafts, samples and confidential documents before sharing them. Add Watermark places semi-transparent text across your pages — diagonally by default, or horizontal — at 20, 40 or 60 percent opacity. A watermark marks a document; it does not remove the underlying content, so it is not a substitute for redaction.
