Frequently Asked Questions
What's the difference between error correction levels?
L (~7%) is basic, M (~15%) is standard, Q (~25%) is good for damaged surfaces, and H (~30%) offers maximum recovery but creates denser codes. Higher levels can recover from more damage but result in larger QR codes.
Should I use PNG or SVG format?
Use PNG for web sharing, social media, and general digital use. Choose SVG for print materials, business cards, and situations where you need perfect scaling at any size.
How much data can a QR code store?
QR codes can store up to 4,296 alphanumeric characters, but practical limits are much lower for reliable scanning. URLs under 100 characters work best for most use cases.
Why isn't my QR code scanning properly?
Ensure sufficient contrast, adequate quiet zone (white border), appropriate size for scanning distance, and test with multiple devices. Higher error correction can help with scanning issues.
Can I customize QR code colors and design?
Our tool generates standard black-and-white QR codes for maximum compatibility. You can customize colors in image editing software, but maintain sufficient contrast for reliable scanning.
