How to Add a Watermark to a PDF

Watermarks protect and brand documents — marking them as Draft or Confidential, or stamping your company name across every page so copies are traceable.

Step by step

1. Open the Watermark PDF tool and add your file.
2. Type the watermark text (e.g. CONFIDENTIAL).
3. Adjust the color, opacity, size and angle.
4. Click Add watermark and download.

Best practices

• Keep opacity around 20–30% so the text underneath stays readable.
• A 45° diagonal watermark is hardest to crop out.
• Use a muted color for branding, red for warnings like "DRAFT".

Frequently asked questions

Is the watermark applied to every page?

Yes — it's stamped across all pages and flattened into the file on download.
