## How to use QR Code Generator

1. **1. Choose your content type** — Select Website URL, Plain Text, Wi-Fi network, Contact Card (vCard), Email, Phone, SMS, Location, Event, WhatsApp, or UPI Payment.
2. **2. Enter your details** — Fill in your data with live standards validation. Payload encoding conforms strictly to documented RFCs and platform standards.
3. **3. Customize colors and design** — Choose module styles (square, rounded, dots, classy), finder eye shapes, gradients, quiet zones, and upload your brand logo with automated finder-pattern safety guards.
4. **4. Validate scanability and export** — Inspect real multi-size decode validation results, check print dimensions at 300 DPI, then download crisp PNG or infinite-resolution SVG vector files.

## Use cases

- Marketing campaigns, business cards, posters, and product packaging needing infinite-resolution vector QR codes.
- Office, cafe, and event Wi-Fi guest cards for frictionless camera scanning without typing passwords.
- Digital payment collection for retail and merchants using standardized UPI payment URIs.
- High-density contact sharing with structured vCard 3.0 digital business cards.
- Batch generation of hundreds of unique labels and asset tags exported as a ZIP package.

## Tips

- Always use SVG vector format when sending QR codes to commercial print shops to ensure razor-sharp module edges.
- Maintain at least a 4-module quiet zone (white border) around the code so camera sensors can isolate the pattern from surrounding graphics.
- When embedding a logo, always select Error Correction Level H (30% recovery) and enable a solid background plate behind the logo.
- Avoid light modules on a dark background; standard phone camera scanners are optimized for dark modules on a high-contrast light background.

## Common problems

- **QR code scans on screen but fails when printed on paper or signs** — Ensure the printed size is at least 20mm × 20mm (for close scanning) with adequate quiet zones and high print contrast. Avoid glossy or reflective paper finishes.
- **The QR code fails to scan after uploading a custom logo** — Reduce the logo size slider below 25%, ensure Error Correction is set to Level H, and verify the logo does not overlap the three square corner finder patterns.
- **Destination URL works today but may change in the future** — Use a canonical URL or branded short link you control so you can redirect the web destination without needing to reprint the static QR code.
- **Wi-Fi QR fails to connect guests automatically** — Check that the SSID name matches your router exactly (case-sensitive) and verify whether the network security type is WPA2/WPA3 or open.

## FAQ

### Do Farvixo QR codes expire?

No. Static QR codes generated here never expire because your content is encoded directly into the pattern of modules. There are no intermediate redirects or third-party tracking links that can break in the future.

### Is my data uploaded to any server?

No. In Static Mode, encoding, rendering, scan validation and image generation happen 100% locally in your browser. Sensitive credentials like Wi-Fi passwords, contact cards, and payment URIs never touch our servers.

### Can I add a custom logo safely?

Yes. You can upload PNG, JPEG, WebP, or SVG logos. The studio enforces safe center positioning, prevents finder pattern collisions, automatically configures error correction (Level H), and validates that real QR decoders can still scan the code.

### Which export format should I use?

Use SVG for all print materials, packaging, signage, and merchandise because vector graphics never blur or pixelate at any size. Use PNG for digital displays, email signatures, websites, and social media.

### Can I customize colors and gradients?

Yes. You can customize foreground, background, and linear/radial gradients. The real-time contrast checker and multi-decoder validation immediately alert you if low contrast threatens scan reliability.

### Can I create Wi-Fi QR codes?

Yes. The Wi-Fi tool creates standard WIFI: payloads compatible with iOS and Android camera scanners, supporting WPA/WPA2/WPA3, WEP, and open networks with hidden SSID toggles.

### Can I generate UPI payment QR codes?

Yes. Farvixo generates compliant UPI payment URIs (upi://pay) that launch Google Pay, PhonePe, Paytm, or BHIM directly on mobile devices. Farvixo never processes or intercepts transactions.

### Can I generate QR codes in bulk?

Yes. Switch to the Batch tab to paste or upload CSV rows. All rows are generated locally, validated individually, and packaged into a convenient ZIP archive with optional manifest.

### Can I use these QR codes commercially?

Yes. All generated QR codes are 100% free with no watermarks, no licensing fees, and no restrictions for commercial or personal use.
