Short, plain answers about adding a text watermark to a PDF in the browser: CONFIDENTIAL and DRAFT labels, opacity and angle, page ranges and readability.

• How to add a watermark to a PDF

  Add a text watermark to a PDF without uploading it: type the text, pick a position, size, angle, opacity and color, check every page, then save a new PDF.

• Add a CONFIDENTIAL or DRAFT watermark

  Mark a PDF as CONFIDENTIAL, DRAFT or COPY with a text watermark in your browser — what to write, which style fits each label, and what a watermark can and can't do.

• Watermark opacity, angle and position

  How the opacity, angle, position and size settings of a PDF watermark work, what the 30% and 45° defaults look like, and when to choose a corner or Tile.

• Watermark only some pages of a PDF

  Put a watermark on a range of PDF pages — for example pages 3 to 7 — and leave the cover and the other pages clean. How the page range works and how to check it.

• A watermark that is visible but readable

  Keep a PDF watermark easy to notice without hiding the text: opacity between 20 and 30%, which color and size to use, when to tile, and when a watermark is the wrong tool.
