Frequently Asked Questions
Do the generated QR codes ever expire?
No. Our generator creates 100% static QR codes where your data is encoded directly into the matrix. They work permanently without subscription fees, limits, or expiration dates.
Can I generate QR codes for Wi-Fi access and vCard contacts?
Yes! You can encode website links, plain text, Wi-Fi credentials (SSID & password), email addresses, phone numbers, and vCard contact info into instant scannable codes.
What is the recommended print size for a QR code?
As a general rule, use a 10:1 ratio for distance to size. For example, if a user scans a flyer from 1 meter away, the QR code should be at least 10 cm (3.9 inches) wide. On business cards, the minimum size should be 2x2 cm (0.8x0.8 in).
Can I customize QR code colors?
Yes. You can customize the foreground and background colors. Always maintain high contrast (dark pattern on a light background) so smartphone cameras can decode the matrix instantly.
What format should I download for printing — PNG or SVG?
Use PNG for digital display, websites, and small prints. Use SVG vector format for professional printing, large banners, and vector design software like Illustrator or Figma, as SVG scales without loss of quality.
What are QR code error correction levels?
Error correction allows QR codes to be read even if damaged or obscured. Levels range from L (7% recovery), M (15%), Q (25%), to H (30%). Higher levels allow embedding logos or withstanding physical wear.

Supported QR Code Data Formats
QR codes support diverse data structures for consumer and business applications. Select your required data payload type below:
| QR Type | Data Payload Format | Primary Real-World Use Case |
|---|---|---|
| URL / Web Link | https://domain.com | Landing pages, menus, social media profiles, digital portfolios. |
| Wi-Fi Network | WIFI:S:SSID;T:WPA;P:Password;; | Instant Wi-Fi auto-connect for cafes, hotels, Airbnb & offices. |
| vCard Contact | BEGIN:VCARD... | Instant contact saving on business cards, brochures & networking. |
| WhatsApp / Direct Chat | https://wa.me/number?text=Hi | Instant customer support, lead generation & message triggers. |
| UPI Payment String | upi://pay?pa=address&pn=Name | Direct contactless UPI payments in India without payment gateway fees. |
| Plain Text | Standard UTF-8 text | Serial numbers, event tickets, Wi-Fi keys & offline instructions. |
Static vs. Dynamic QR Codes — Which Do You Need?
Understanding the technical difference between static and dynamic QR codes ensures your campaign remains reliable over time:
- Static QR Codes (This Tool): The data (URL, text, Wi-Fi, contact) is encoded directly into the matrix pattern. They never expire, require no central server or tracking domain, and continue working indefinitely without recurring charges.
- Dynamic QR Codes: The matrix contains a redirect short link pointing to a third-party server. If the service provider shuts down or charges fees, the QR code breaks.
QR Code Error Correction Levels Explained
QR codes use Reed-Solomon error correction to remain scannable even when partially damaged, dirty, or covered by a custom logo icon. Higher error correction levels increase matrix density while preserving scannability:
| Error Correction Level | Data Recovery | Best Recommended For |
|---|---|---|
| Level L (Low) | 7% Data Recovery | Clean digital displays & dense URLs with low physical wear. |
| Level M (Medium) | 15% Data Recovery | Default standard — ideal balance for flyers, packaging & stickers. |
| Level Q (Quartile) | 25% Data Recovery | Outdoor posters, floor graphics & high-traffic environments. |
| Level H (High) | 30% Data Recovery | Embedding brand logos & designs with heavy physical exposure. |
Print Sizing & Scan Distance Formula
To ensure smartphone cameras can focus and decode printed QR codes reliably across various distances, follow the 10:1 distance-to-size rule:
- Business Cards (0.3m scan distance): Minimum size 2.0 cm × 2.0 cm (0.8 in × 0.8 in).
- Table Tents & Menus (0.5m scan distance): Minimum size 3.5 cm × 3.5 cm (1.4 in × 1.4 in).
- Flyers & Posters (1.0m scan distance): Minimum size 10.0 cm × 10.0 cm (3.9 in × 3.9 in).
- Outdoor Billboards (10.0m scan distance): Minimum size 100 cm × 100 cm (39 in × 39 in).
Best Practices for Custom Color Contrast
Smartphone camera sensors detect QR codes by identifying high contrast differences between the foreground matrix modules and background space:
- Always use high contrast: Dark foreground (black, deep navy, dark purple) on a light background (white, cream, light grey).
- Avoid inverted colors: Light patterns on dark backgrounds fail to scan on older Android and iOS camera modules.
- Maintain a Quiet Zone: Keep a clean margin (at least 4 modules wide) around the outer border of the QR code matrix.
