About Add watermark

Add watermark stamps text such as DRAFT, CONFIDENTIAL or your name across pages, discouraging misuse and making the status of a document obvious at a glance.

When people use it

Marking drafts so they are not mistaken for final versions.
Labelling copies of ID sent to a specific organisation ("For bank KYC only").
Branding sample documents shared with clients.

Tips for better results

Lower opacity keeps the content readable.
A diagonal watermark is harder to crop out.
Flatten afterwards so the watermark cannot be easily removed as an annotation.
