Preguntas Frecuentes
What types of data can I encode in a QR code?
QR codes can encode URLs, plain text, phone numbers, SMS messages, email addresses, WiFi credentials (SSID + password), contact cards (vCard), calendar events, and geographic coordinates.
What is the maximum data a QR code can hold?
QR codes can hold up to 7,089 numeric characters, 4,296 alphanumeric characters, or 2,953 bytes of binary data. For URLs, keep them short — longer URLs require higher QR code density which may be harder to scan.
What do the error correction levels mean?
Error correction allows QR codes to be read even if partially damaged: L (7%), M (15%), Q (25%), H (30% of data can be recovered). Use H for printed QR codes that may get dirty or damaged. Use L for digital displays where you want smaller codes.
Is it safe to generate QR codes in the browser?
Yes. All QR code generation happens client-side in your browser using the qrcode library. No data is sent to any server.
