Before distributing sensitive financial projections, contract drafts, or proprietary creative work, applying clear watermarks like "CONFIDENTIAL", "DRAFT", or "DO NOT SHARE" prevents unauthorized leaks and protects ownership.

iLoveTools Watermark PDF allows you to add customizable text stamps with adjustable opacity, rotation angles, and colors across every page of your document.

Because all watermarking occurs locally inside your browser memory, your confidential drafts and agreements are never exposed to external cloud servers.
