About the Watermark PDF
Handytool's Watermark PDF tool stamps a custom text watermark across every page of your document. Type your text — CONFIDENTIAL, DRAFT, your name — then tune the size, opacity, color, and whether it sits diagonally across the page. The watermark is applied locally in your browser, so even sensitive documents stay on your device.

Watermark PDF FAQ
- Is the watermark added to every page?
- Yes. The text watermark is stamped onto all pages of the PDF in one pass.
- Can I make the watermark see-through?
- Yes. Lower the opacity so the watermark sits lightly over your content without making the text hard to read.
- Can I add an image or logo watermark?
- This tool adds a text watermark. For a logo, you can recreate the wording as text and adjust the color and size to match your branding.
- Are my files uploaded?
- No. Everything runs locally in your browser — your file is never uploaded to a server.
