About

PDF Watermark
A Chrome extension that adds text watermarks to PDFs entirely in your browser. Files never leave your machine. No upload, no server, no telemetry.

Features
- Drag-and-drop or click to load a local PDF
- Watermark with English, Chinese (simplified), or mixed text
- Live preview of the first page
- Adjustable parameters: opacity, rotation angle, font size, color
- Three layout presets: single (centered), 2×2 grid, 3×3 grid
- Output PDF preserves the original content; watermark sits on top of every page
- Files up to 100 MB

Privacy
This extension runs 100% locally:
- No network requests of any kind
- No data collection or analytics
- No background page or service worker watching your activity
- The permissions field in manifest.json is empty
- All processing (PDF parsing, font embedding, watermark drawing) happens in the popup, in your own Chrome process
