TeamSync PDF Viewer SDK

100% Open Source. 100% Client-Side. Enterprise PDF Engine.

No paywalls. No vendor lock-in. No server dependencies.
Integrate a high-performance, drop-in PDF Viewer SDK directly into your React applications and unlock commercial-grade features completely free.

🚀 Why TeamSync PDF Viewer?

Traditional commercial PDF viewers force developers into expensive per-domain licenses, opaque sales calls, and heavy server-side processing dependencies. TeamSync PDF Viewer is built from the ground up to solve these pain points.

• 💰 Zero-Cost, Transparent Licensing: Uncapped usage, no per-server fees, and no commercial paywalls. 100% free and open-source under CPAL 1.0.
• ⚡ 100% Client-Side WebAssembly: Documents never leave the browser sandbox. Process, redact, and render PDFs entirely on the client—guaranteeing instant HIPAA, GDPR, and FINRA compliance.
• 🔌 Universal WebViewer API: Clean, intuitive WebViewer({...}) API interface that makes integrating into your web applications effortless.
• 🎨 Headless & Customizable: Built for modern React 19 SPA lifecycles. No bloated iFrames to fight—customize toolbars, sidebars, context menus, and controls natively.

✨ Uncompromised Feature Set

Everything you need to build collaborative, secure document workflows.

🎨 Smart Markup & Annotations

• Full Drawing Toolkit: Freehand ink (brush), highlighters, geometric shapes (rectangles, ellipses), arrows, and lines.
• Notes & Callouts: Sticky notes, callout text boxes with directional arrows, and text annotations.
• Interactive Hyperlinks: Create internal page-jump links (#page=N) or external web URL links directly on document selections.

🛡️ Military-Grade Secure Redaction

• Binary-Level Data Obliteration: We don't just place black boxes over text—redactions are permanently rasterized and burned into the underlying PDF vector structure.
• Text Layer Sanitization: Redacted text is automatically stripped from the DOM textLayer and PDF content streams, preventing copy/paste extraction and search indexing.
• Automatic Regex Redactions: Programmatically locate and redact sensitive PII (Aadhaar numbers, SSNs, credit cards, dates of birth) in a single click.
• Discard Unapplied Redactions: Easily discard individual pending redactions or bulk-discard all unapplied redaction marks before committing.

🔍 High-DPI Canvas Rendering & Search

• Retina 60 FPS Zoom & Pan: High-DPI devicePixelRatio scaling eliminates blurred text. Micro-debounced rendering enables buttery-smooth 60 FPS trackpad pinching and 360° mouse drag panning.
• Contextual Document Search: Instant client-side text search with real-time match highlighting, result jumping, and match counting.

💧 Dynamic Forensic Watermarking

• Programmatic, non-destructive watermarks rendered on the fly (single centered or full-page tiled) with customizable text, color, opacity, font size, and rotation.

💻 Developer SDK Usage

Standard WebViewer Initialization

Drop the SDK into any container element with a single function call:

import { WebViewer } from '@angelbot-ai/teamsync-pdf-viewer';
import '@angelbot-ai/teamsync-pdf-viewer/style.css';

WebViewer({
  initialDoc: '/sample.pdf',
  initialScale: 1.0, // 100% natural size
  enableAnnotations: true,
  permissions: {
    canRedact: true,
    canAddAnnotations: true
  },
  watermark: {
    text: 'CONFIDENTIAL',
    mode: 'single',
    size: 48,
    opacity: 0.1,
    color: '#dc2626'
  }
}, document.getElementById('viewer-container')).then((instance) => {
  console.log('TeamSync PDF Viewer is ready!', instance);
  
  // Export annotated PDF buffer
  instance.Core.documentViewer.getDocument().getFileData().then((pdfBytes) => {
    console.log('Exported PDF byte length:', pdfBytes.length);
  });
});

Native React Component Usage

For native React integration, use the <DocumentViewer /> component:

import { DocumentViewer } from '@angelbot-ai/teamsync-pdf-viewer';
import '@angelbot-ai/teamsync-pdf-viewer/style.css';

function App() {
  return (
    <div style={{ width: '100vw', height: '100vh' }}>
      <DocumentViewer
        initialDoc="/contract.pdf"
        scale={1.0}
        enableAnnotations={true}
        permissions={{ canRedact: true }}
      />
    </div>
  );
}

🛠️ Local Development Quick Start

1. Clone & Install

git clone https://github.com/angelbot-ai/TeamSync-PDF-Viewer.git

🔌 Extensible Plugin Architecture

TeamSync PDF Viewer features a decoupled Plugin Architecture. Core PDF rendering, smart annotations, redaction engines, and search remain lightweight and modular in the main engine, while enterprise extensions plug in as independent modules.
