Practical guidance

Add a custom text watermark to PDF pages

Watermark PDF places visible text such as DRAFT, SAMPLE, CONFIDENTIAL, or a review label across the document. Control the colour, position, rotation, size, and opacity, then review the result before creating the watermarked copy.

Watermark every PDF page consistently

A shared watermark creates a recognizable document status or ownership notice across the complete PDF.

Adjust watermark visibility

Use opacity, colour, size, rotation, and placement to keep the notice visible without making the page impossible to read.

Use a watermark as a notice, not protection

A visible watermark can communicate status or ownership, but it does not encrypt the document or prevent copying.
