PDF watermark: what it is and how to use it

What is PDF watermark?

PDF watermarking adds a visible label such as “draft” or a brand mark; it improves traceability but is not a full leak-prevention solution. CodeGrid Tools generates watermarked PDFs in the browser so you avoid unnecessary cloud retention of the source. Tune opacity and branding for professional output. File-tool quotas and Pro tiers apply. This guide explains when PDF watermark helps and how to run it step by step in CodeGrid Tools.

When is it useful?

• Add a watermark to your PDF
• Runs in your browser—no extra software required

Can the watermark be text or an image?
A text watermark, such as DRAFT or CONFIDENTIAL, is written directly on the page; transparency and size can be adjusted. Is it applied to all pages?
Yes. The same watermark pattern is added to every page in the document. Can I remove the watermark later?
This tool creates a permanently embedded watermark. To remove it, you would need the original source PDF. Use PDF watermark →
