How to Create a QR Code
QR codes (Quick Response codes) are two-dimensional barcodes that can store URLs, text, contact information, WiFi credentials, and more. They are scanned using smartphone cameras and are widely used in marketing, restaurants, events, and business cards. This guide walks you through creating QR codes for any purpose using free browser-based tools.
Step 1: Choose the QR Code Type
Decide what information you want to encode. The most common types are URL (website links), WiFi (network credentials), vCard (contact information), email, and SMS. Each type has specific input fields — for example, a WiFi QR code requires the network name (SSID), password, and security type.
Step 2: Enter Your Information
Fill in the required fields for your chosen QR code type. For a URL QR code, paste the full website address including https://. For WiFi, enter the exact SSID and password. Double-check all information before generating — typos will make the QR code link to the wrong destination or fail to connect.
Step 3: Customize Appearance
Most QR generators allow you to adjust the size and foreground color of the QR code. Keep the contrast high (dark code on light background) for reliable scanning. Avoid using light colors for the QR modules as they reduce scannability.
Step 4: Generate and Download
Click the generate button to create your QR code. Download it as PNG for digital use or SVG for print materials. PNG is best for websites and social media, while SVG scales to any size without losing quality.
Best Practices
Always test your QR code before printing or sharing. Use a minimum size of 2×2 cm for print. Ensure adequate quiet zone (white space) around the code. For critical applications, use high error correction levels so the code remains scannable even if partially damaged.
Common Mistakes to Avoid
Don't use low contrast colors (light gray on white). Don't make the QR code too small for the scanning distance. Don't forget to test the code with multiple devices. Don't encode excessively long text — shorter data creates simpler, more reliable codes.

Frequently Asked Questions
- Are QR codes free to create?
- Yes. Static QR codes can be created for free using browser-based tools. The QR code standard is open and no license is required.
- Do QR codes expire?
- Static QR codes do not expire — they encode fixed data. However, if the QR code links to a URL that is later taken down, the code will still work but the destination will be unavailable.
- What is the maximum data a QR code can store?
- A QR code can store up to 4,296 alphanumeric characters or 7,089 numeric characters. For practical use, shorter data creates simpler, more reliably scannable codes.
