Best use cases
Key settings
Presets
One-click common watermark texts — DRAFT, CONFIDENTIAL, PROOF, COPY, SAMPLE, DO NOT COPY.
Clicking a preset fills the text field. You can further customize after selecting a preset. Presets use the current appearance settings (font size, color, opacity, angle).
Text
The watermark message displayed on every page. Short, all-caps text works best.
Supports any text string. Longer text may need a smaller font size to fit. Common patterns: "DRAFT", "PROOF #3", "CONFIDENTIAL", "FOR REVIEW ONLY", "SAMPLE — NOT FOR DISTRIBUTION".
Appearance
Controls font size, color, opacity, and rotation angle of the watermark text.
Font size: in points — 72pt is typical for full-page diagonal watermarks on Letter/A4. Larger pages may need 96–144pt. Color: any hex color — gray (#888888) is standard for subtle marks, red (#cc0000) for attention-grabbing. Opacity: 10–20% for subtle background marks, 30–50% for clearly visible stamps. Angle: 45° for classic diagonal, 0° for horizontal, 90° for vertical.
Pages
Specify which pages to process using a range expression.
Examples: 'all' = every page. '1-5' = pages 1 through 5. '1,3,5' = specific pages. '1-10 odd' = odd pages 1-9. '2-20 even' = even pages 2-20. 'last' = last page. 'last-2' = third from last. Ranges are 1-based. Combine with commas: '1-5, 8, 12-15'.

Expert tip
For proofs, use 45-degree rotated text at 10-15% opacity across each page. The watermark should be obvious enough to deter unauthorised use but light enough not to obscure the content.
Watermarks at very low opacity (below 5%) may not survive JPEG compression in digital proofing systems. Test visibility on your actual proofing workflow.
