Updated April 2026

What it does

Stamp a text watermark across every page of a PDF — DRAFT, CONFIDENTIAL, your company name, a client reference. You pick the text, size, color, opacity, rotation, and one of six positions. The watermark is a real PDF layer (not a bitmap overlay), so the underlying document stays searchable and selectable.

Good watermarks signal status; they don’t replace real protection. Anyone who wants to can re-OCR and clean it off. For shared drafts and work samples the signal is enough — for actual confidentiality, limit distribution. For practical guidance on text and styling, see How to add a watermark to a PDF.

How to use it

  1. Drop the PDF you want to watermark.
  2. Type the watermark text (e.g. DRAFT or your name).
  3. Pick size, color, opacity, rotation, and position.
  4. Click Apply — download the watermarked file.
