Frequently Asked Questions
Can I add an image as a watermark? ▼
The current tool supports text watermarks. For image watermarks, use the Sign PDF / Add Stamp tool to place an image on pages.
Does the watermark work on all pages? ▼
Yes — the watermark is applied to every page of the PDF uniformly.
Can the watermark be removed? ▼
Text watermarks on PDFs can be challenging to remove without the original file, especially at higher opacity. For true security, combine with PDF encryption.
Opacity, Colour, and Placement Guide
Watermark opacity balances visibility against readability. 10–20%: subtle, informational, content fully readable. 30–50%: clearly visible "DRAFT" or "CONFIDENTIAL" while content remains usable. 60%+: dominant — used for sample documents or previews where content should be difficult to use without the final. Diagonal placement at 45° is standard because it's visually harder to remove than horizontal text and overlaps more content areas on the page.
For maximum document control, combine watermarking with password protection: watermark first to add the visible label, then use Protect Files to add a password. This creates two complementary layers of access control — visual identification for anyone who opens the file, and encryption to restrict who can open it in the first place.
