About Watermark PDF Tool
Protect your intellectual property or label document status by stamping custom text watermarks (e.g. 'CONFIDENTIAL', 'DRAFT', or your brand name) on every page of your PDF file. Customize the text, color, rotation angle, size, and opacity to fit your branding.
The watermarking process is performed client-side using pdf-lib. No external server receives your document, keeping your pre-release drafts and confidential files secure.
