Why Watermark a PDF?
Watermarks serve as a visible indicator of a document's status or ownership. The most common uses include marking documents as DRAFT to prevent premature distribution, CONFIDENTIAL to discourage unauthorized sharing, or adding a company name to branded materials. Watermarks do not prevent copying, but they make the document's intended status immediately clear to anyone who views it.
How Watermarking Works
Breezy PDF draws your watermark text diagonally across the center of every page as a semi-transparent overlay. The text is rendered using pdf-lib directly in your browser — your document is never uploaded anywhere. You control the text content, font size, and opacity level. Lower opacity creates a subtle background mark; higher opacity makes the watermark more prominent and harder to ignore.
Common Watermark Text
DRAFT — for documents still under review. CONFIDENTIAL — for sensitive materials with restricted distribution. SAMPLE — for example documents or templates. DO NOT COPY — for materials that should not be reproduced. You can also use your company name, a date, or any custom text.
After watermarking, you might want to add page numbers for professional formatting, or compress the result before distributing. All tools process your files locally with no uploads.
