QR Code Generator

📖 Description

1. Why Do You Need a QR Code Generator?

QR codes have become a bridge connecting the physical and digital worlds, with extremely wide applications:

• Marketing & Lead Generation: Convert website URLs or campaign pages into QR codes for printing on posters, flyers, or business cards, making it easy for users to scan and visit.
• Information Sharing: Quickly encode text, Wi-Fi passwords, or payment links, eliminating the hassle of manual entry.
• Paperless Office: Attach electronic manual QR codes to product packaging, saving printing costs and facilitating content updates.
• Personalized Branding: Customize colors and add logos to transform QR codes from monotonous black-and-white blocks into part of your brand's visual identity.

2. Core Features Explained

This site's tool provides a full-process solution from encoding to beautification, ensuring every generated code is both aesthetically pleasing and practical:

A. Diverse Encoding Support

• Text/URL: The most basic and commonly used feature, supports long link shortening and preview.
• Digital Business Card (vCard): Scan to save name, phone number, and email directly to a phone's contacts.
• Wi-Fi Access: Automatically configures SSID and password, allowing guests to connect by scanning.
• Social/Payment: Encode social media profile links or payment requests in specific formats.

B. Deep Customization & Beautification

• Color Adjustment: Supports setting foreground (code dot) and background colors, even gradient color designs.
• Logo Embedding: Upload and place a personal avatar or company logo in the center of the QR code, with automatic handling of the occluded area to ensure readability.
• Error Correction Level Setting: Provides four adjustable error correction levels ($L, M, Q, H$). With high error correction ($H$), the code can still be scanned normally even if up to $30%$ is damaged or covered by a logo.
• Dot Shape: Besides traditional squares, choose from artistic shapes like circles, liquid, and more.

C. High-Definition Vector Export

• Multi-Format Output: Supports exporting common formats like PNG, JPG, and vector format SVG suitable for professional printing.
• Size Adjustment: Freely set pixel values, from small sizes for web display to large sizes for outdoor advertising.

D. Privacy & Offline Generation

• Local Processing: The core encoding algorithm runs locally in your browser. Your sensitive information (e.g., Wi-Fi passwords) is not uploaded to any server, ensuring data privacy and security.
