What is a QR Code?
A QR (Quick Response) code is a two-dimensional barcode that stores information in a pattern of black and white squares. Invented in 1994 by Denso Wave for tracking automotive parts, QR codes have become ubiquitous for sharing URLs, contact information, and other data.
Unlike traditional barcodes that store data horizontally, QR codes store data in both horizontal and vertical directions, allowing them to hold significantly more information. They can be scanned quickly from any angle using smartphone cameras.
Frequently Asked Questions
What can I encode in a QR code?▼
You can encode any text data including URLs, plain text, Wi-Fi network credentials (SSID and password), email addresses, phone numbers, SMS messages, vCard contact info, and more. The QR code standard supports up to about 3,000 alphanumeric characters.
Is this QR code generator free?▼
Yes, our QR code generator is completely free with no registration required. Generate unlimited QR codes, customize colors and sizes, and download without watermarks.
What is error correction in QR codes?▼
Error correction allows QR codes to remain scannable even if partially damaged or obscured. Our generator uses 'High' level error correction (H), which can restore up to 30% of the data if the code is damaged. This is the highest level available.
What size should I make my QR code?▼
For digital use (websites, emails), 200-300px is usually sufficient. For print materials, use larger sizes (300-512px) and ensure adequate resolution. The minimum scannable size depends on scanning distance - generally 2cm x 2cm for close-range scanning.
Can I customize the colors of my QR code?▼
Yes! You can customize both foreground (the dark modules) and background colors. For best scanning results, maintain high contrast between the two colors - dark foreground on light background works best.
Do the QR codes expire?▼
No, QR codes don't expire. They simply encode data - if that data is a URL, the URL itself would need to remain active. Static QR codes (like the ones we generate) will work forever as long as the encoded content remains valid.
