Quick Start Guide
Choose between a URL, WiFi Configuration, or Plain Text. Each mode has optimized fields for faster entry.
Paste your link or configuration. Watch the QR code pattern update in real-time as you type every character.
Select the Error Correction level. Use "High" if you plan to print the code on a textured surface or add a logo in the center.
Adjust the foreground and background colors. Always ensure high contrast (dark on light) for maximum scannability.
Before downloading, aim your phone camera at the screen to confirm the code works exactly as intended.
Select PNG for digital use or SVG for professional printing and physical signage.

Technical Architecture
Reed-Solomon redundancy
We implement the Galois Field mathematical model to generate error correction codewords. This ensures that the QR code remains a robust data carrier even in suboptimal lighting or physical conditions.
Optimal Masking Selection
Our generator automatically tests all 8 standard QR masks and selects the one with the lowest "penalty" score, ensuring the pattern is as easy as possible for mobile cameras to parse.
Client-Side Canvas Rendering
We use an off-screen canvas buffer to draw the QR modules before exporting. This ensures that the user interface stays snappy even while generating complex 40x40 grid patterns.
Standardized WiFi URI Schema
Our WiFi generator follows the 'WIFI:S:<SSID>;T:<TYPE>;P:<PASS>;;' protocol, which is the industry standard recognized by Apple and Google mobile operating systems.
