A QR Code (Quick Response Code) Generator is a powerful tool that creates two-dimensional barcodes capable of storing various types of information in a compact, scannable format. Our QR Code Generator allows you to instantly create QR codes for text, URLs, contact information, WiFi credentials, and more, with customizable size and error correction levels. QR codes bridge the gap between physical and digital worlds, enabling quick data transfer through simple smartphone scanning. Whether you're creating marketing materials, sharing contact information, providing WiFi access, or distributing links, QR codes offer a convenient, mobile-friendly solution. The generated codes are compatible with all standard QR code readers and can be downloaded in multiple formats for print or digital use. This tool processes everything client-side, ensuring your data privacy while providing professional-quality QR codes suitable for business cards, flyers, presentations, and digital displays.
When to Use QR Code Generator
Use our QR Code Generator whenever you need to share information quickly and conveniently through mobile scanning. This tool is essential for marketing campaigns where you want to drive traffic from print materials to websites, sharing WiFi passwords with guests without revealing credentials, distributing contact information at networking events, or creating touchless menus for restaurants. Business owners commonly use it for linking to social media profiles, product pages, or promotional offers from physical advertisements. It's particularly valuable for event management (linking to registration or information pages), educational materials (providing additional resources), and customer service (linking to support pages or feedback forms). The tool is also perfect for personal use like sharing your contact details, creating digital business cards, or providing easy access to your social media profiles at events or meetups.

Pro Tips
7 tipsKeep content under 300 characters for reliable mobile scanning across all devices
Use Medium error correction level for the best balance of reliability and scannability
Test QR codes on multiple devices and apps before final use
Ensure high contrast when printing - black on white works best
Size QR codes appropriately: minimum 2cm x 2cm for reliable scanning
Add a brief text explanation near QR codes to encourage scanning
For URLs, use URL shorteners if the original link is very long to reduce QR code complexity
Frequently Asked Questions
5 Q&AQ1:What types of data can I encode in QR codes?
QR codes can store various data types including plain text, URLs, email addresses, phone numbers, SMS messages, WiFi credentials, contact information (vCard), and even small amounts of binary data. The maximum capacity depends on the data type and error correction level.
Q2:What's the maximum amount of data a QR code can hold?
QR codes can store up to 4,296 alphanumeric characters, 7,089 numeric characters, or 2,953 bytes of binary data. However, practical limits are lower due to scanning reliability - we recommend keeping text under 300 characters for best mobile scanning performance.
Q3:What do the different error correction levels mean?
Error correction allows QR codes to be readable even when partially damaged. Level L (Low) recovers ~7% damage, M (Medium) ~15%, Q (Quartile) ~25%, and H (High) ~30%. Higher levels create denser codes that may be harder to scan, so Medium is usually the best balance.
Q4:Why won't my QR code scan properly?
Common scanning issues include: insufficient contrast, too small size (minimum 2cm for reliable scanning), damaged or dirty codes, poor lighting, or trying to scan complex codes from far away. Ensure high contrast and adequate size for your use case.
Q5:Can I customize the appearance of QR codes?
While our generator focuses on standard black-and-white codes for maximum compatibility, QR codes can be customized with colors, logos, and styling. However, any modifications should maintain sufficient contrast and not obscure the positioning markers for reliable scanning.
