Frequently Asked Questions
What can I encode in a QR code?
QR codes can store text, URLs, email addresses, phone numbers, WiFi credentials, contact information (vCard), SMS messages, geographic coordinates, and much more. The limit is typically 2,953 bytes for binary data.
What do error correction levels mean?
Error correction allows QR codes to be readable even when partially damaged. Low (7%) is for clean environments, Medium (15%) for general use, Quartile (25%) for industrial use, and High (30%) for harsh conditions where damage is likely.
What's the difference between PNG and SVG downloads?
PNG creates a raster image perfect for printing and sharing. SVG creates a vector graphic that scales infinitely without quality loss, ideal for websites, logos, and professional printing at any size.
