Frequently Asked Questions
What is error correction in QR codes?
Error correction allows a QR code to be read even if part of it is damaged or obscured. Four levels are available: L (Low) recovers ~7%, M (Medium) ~15%, Q (Quartile) ~25%, and H (High) ~30% of the code. Higher levels create larger QR codes but are more resilient.
What is the maximum data capacity of a QR code?
QR codes can store up to 7,089 numeric characters, 4,296 alphanumeric characters, or 2,953 bytes of binary data. However, larger data amounts create denser codes that are harder to scan. For best results, keep URLs short and data concise.
Can I use these QR codes commercially?
Yes, the QR codes generated by this tool are free to use for both personal and commercial purposes. They contain no watermarks or restrictions. You can use them on products, marketing materials, business cards, and more.
