Sharing draft contracts, proprietary financial projections, or intellectual property without branding puts your work at risk of unauthorized distribution.
Adding a semi-transparent watermark makes it immediately clear that the document is confidential, copyrighted, or in draft status.
ToolsVerse lets you stamp customized text (with adjustable opacity, rotation, and font size) or transparent PNG logos across your PDF locally in your browser.
💡The Core Challenge
Many watermarking tools stamp rigid, opaque blocks that obscure readable document text. ToolsVerse provides fine opacity and layer positioning controls.
Step-by-Step Guide

Drop your PDF into the ToolsVerse Watermark tool.
Customize Your Watermark
Type your text (e.g. "CONFIDENTIAL", "SAMPLE", "DRAFT") or upload a company logo PNG.
Fine-Tune Appearance
