Generate High-Precision QR Codes in SVG & PNG
Create high-density, error-resilient QR codes for URLs, WiFi networks, vCards, crypto addresses, and plain text. Download scalable vector SVG files for crisp print production or high-DPI PNGs.
Step-by-Step Instructions
Input Target Data
Enter any website URL, WiFi SSID/password credentials, contact vCard, or custom text.
Select Error Correction
Choose Reed-Solomon correction level (L: 7%, M: 15%, Q: 25%, H: 30% recovery capability).
Matrix Generation & Masking
The algorithm evaluates standard penalty rules (Pattern 0–7) to ensure optimal scanner readability.
Export Vector SVG or PNG
Download crystal-clear vector files that never lose quality when enlarged for billboards or print packaging.
🔒 Privacy & Data Security Guarantee
100% Private Data Encoding: WiFi passwords, personal phone numbers, and secret tokens are never logged or stored.
Reed-Solomon Error Correction & Galois Field Math
QR codes rely on Reed-Solomon error correction over Galois Field GF(256). This mathematical redundancy allows scanners to reconstruct damaged, smudged, or partially obscured QR codes without data loss.
Selecting Level H (High - 30% recovery) is essential if you plan to overlay a custom logo in the center of the code or print on outdoor signage exposed to dirt and physical wear.
Reed-Solomon Error Correction Levels
| Level | Data Recovery Capacity | Matrix Density | Recommended Application |
|---|---|---|---|
| Level L (Low) | ~7% of codewords can be restored | Lowest (Smallest dots) | Clean digital displays, mobile screens, tiny print areas |
| Level M (Medium) | ~15% of codewords can be restored | Standard | Standard brochures, marketing collateral, business cards (Default) |
| Level Q (Quartile) | ~25% of codewords can be restored | High | Industrial packaging, manufacturing barcodes, restaurant menus |
| Level H (High) | ~30% of codewords can be restored | Highest (Denser grid) | QR codes with central logos, outdoor posters, vehicle wraps |
