Built with a focus on modern UI/UX, privacy, and the ability to handle complex web elements like Canvas and SVG-based QR codes that traditional scanners fail to recognize. Overview QR-SnG is more than a simple barcode reader; it is a comprehensive toolkit for managing digital data. Whether you need to generate a high-quality vector QR code for a business card or extract data from a stubborn CSS-styled QR code on a webpage, this extension provides a robust, Manifest V3-compliant solution. Key Features 🔍 Advanced Scanning Capabilities

jsQR Integration: Utilizes the synchronous jsQR engine for 100% Manifest V3 CSP compliance. No external web workers are required, ensuring maximum security and performance.
Multi-Input Support: Scan QR codes via file upload, standard right-click context menus, or by simply dragging and dropping an image file anywhere into the side panel.
Smart Parser: Automatically detects the data type of scanned codes (Wi-Fi, vCard, URL, etc.) and presents a formatted, interactive UI rather than raw text.

🎨 Professional QR Generatio

Smart Templates: Dedicated forms for generating specialized QR codes:
Wi-Fi: SSID, Password, and Encryption type.
vCard: Full contact details (Name, Phone, Email).
Communication: Email (Subject/Body) and SMS/WhatsApp integration.
Geolocation: Latitude/Longitude with a built-in City Search (OpenStreetMap API) to auto-fill coordinates.
Deep Customization:
Shape Control: Customize "Data Dots" and "Position Eyes" independently (Squares, Circles, Rounded, or Liquid styles).
Visual Aesthetics: Support for solid colors, linear gradients, and transparent backgrounds.
Contrast Validator: Real-time scannability check that warns you if your color choices provide insufficient contrast for physical scanners.
Large Text Hosting: A unique feature that handles massive text payloads by hosting the content on a secure web viewer and generating a lightweight, scannable "Compressed Link" QR code instead.

📂 History & Management

Intelligent History Log: Saves your recent scans and generations locally.
Favorites & Recycle Bin: Organize your codes with a "Starred" system. Deleted items move to a Recycle Bin with a 30-day auto-purge cycle, similar to modern OS behavior.
Smart File Naming: Automatically names downloaded files based on their content (e.g., QR-SnG_github.com-my-project.png), truncated to 50 characters for easy recognition.

Advanced Technology URL Shortening & Fallback The extension integrates the TinyURL API to ensure that long, complex URLs result in simple, high-density QR codes that are easier for mobile devices to scan. It features a dual-API fallback system to ensure the service remains available even if a specific API key reaches its limit. Privacy & Performance

No Camera Required: Unlike legacy scanners, this tool requires zero camera permissions, making it ideal for PCs and privacy-conscious users.
Dark Mode: A fully native Dark Mode toggle that respects user preferences and reduces eye strain.
Local Processing: All QR decoding and matrix generation happen locally on your machine; your data is never sent to a third-party server for processing (except optional URL shortening).
