Adding Watermarks

Add text or image watermarks to your PDFs for draft labels, confidentiality marks, and branding.

Overview

Watermarks are semi-transparent elements placed behind document content. They're used for draft markers, confidentiality labels, branding, and copy protection.

Text Watermark

Create a diagonal "DRAFT" or "CONFIDENTIAL" watermark:

  1. Add a text element with your watermark text (e.g., "DRAFT")
  2. Set font size to 72–100px, bold
  3. Set text color to a light gray with low opacity (e.g., rgba(0, 0, 0, 0.08))
  4. Rotate the element to -45 degrees (diagonal)
  5. Center it on the page
  6. Enable "Repeat on all pages" for multi-page documents
  7. Send the element to back so content appears on top

Opacity

Keep watermark opacity between 5–15% so it's visible without interfering with read­ability. Test with different background colors.

Image Watermark

Use a company logo as a subtle background watermark:

  1. Add an image element with your logo
  2. Set opacity to 5–10%
  3. Scale to cover most of the page (e.g., 300×300px, centered)
  4. Send to back and enable repeating

Conditional Watermarks

Show watermarks only in certain conditions using conditional content:

  • Draft documents — Show "DRAFT" when status is "draft"
  • Copies — Show "COPY" when isCopy is true
  • Void — Show "VOID" on cancelled invoices
  • Sample — Mark demo or preview documents

Design Guidelines

  • Use a single color (gray works best on any background)
  • Don't make the watermark darker than 15% opacity
  • Diagonal placement (45°) is most effective and traditional
  • Centered placement works for most page sizes
  • Uppercase text with letter spacing improves recognition
  • Test on both light and dark template areas
