📱 Complete Guide to QR Codes
QR (Quick Response) codes have become an essential tool for instantly sharing information. Whether you're a business owner, marketer, event organizer, or just want to share your WiFi password, QR codes provide a fast, contactless way to transfer data with a simple scan.
What Are QR Codes?
QR codes are two-dimensional barcodes that can store significantly more information than traditional barcodes. They were invented in 1994 by Denso Wave, a Toyota subsidiary, and have since become ubiquitous worldwide. A single QR code can hold up to 4,296 alphanumeric characters or 7,089 numeric characters.

How to Use QR Codes Effectively
- Size Matters: Print QR codes at least 2x2 cm (0.8x0.8 inches). Larger is better for scanning from a distance.
- Contrast is Key: Always use dark codes on light backgrounds. Black on white works best.
- Test Before Publishing: Scan your QR code with multiple devices and apps to ensure it works correctly.
- Add a Call-to-Action: Tell people what they'll get when they scan - "Scan for menu," "Scan to connect," etc.
- Consider Placement: Position QR codes at eye level and in well-lit areas for easy scanning.
- Don't Add Too Much Data: Keep content concise. More data = more complex code = harder to scan.

Frequently Asked Questions
Q: Are QR codes secure?
A: QR codes themselves are just data - they're as secure as the content they contain. Be cautious of QR codes from unknown sources, as they could link to malicious websites. Always preview the URL before visiting, and never scan QR codes that ask for sensitive information like passwords or credit card numbers.
Q: Do QR codes expire?
A: Static QR codes (like the ones generated here) never expire. The code will always contain the same data. However, if the code links to a URL and that website goes down or changes, the QR code will no longer work as intended.
Q: Can I customize the appearance of QR codes?
A: Yes! Our generator lets you customize QR code colors with preset options (black, teal, blue, red, etc.) or choose any custom color. You can also add your own logo to the center with adjustable sizing. Maintain good contrast and don't cover more than 30% of the code with a logo to ensure scannability.
Q: What's the difference between static and dynamic QR codes?
A: Static QR codes (like ours) have data embedded directly in the code and cannot be changed once created. Dynamic QR codes use a short URL that redirects to your actual content, allowing you to change the destination without reprinting the code. Dynamic codes require a paid service for tracking and management.
Q: How much data can a QR code hold?
A: A QR code can theoretically hold up to 4,296 alphanumeric characters. However, the more data you include, the more complex and dense the code becomes, making it harder to scan. For best results, keep URLs under 100 characters and text content concise.
Q: Can damaged QR codes still work?
A: Yes! QR codes have built-in error correction. Depending on the error correction level, they can still be scanned even if up to 30% of the code is damaged or obscured. This is why you can add logos to the center of QR codes.
