Perguntas frequentes
▶O que é um QR code?
Um QR code é um código de barras bidimensional que pode armazenar texto, URLs e outros dados. Pode ser escaneado com a câmera do smartphone.
▶Existe limite de tamanho do texto?
QR codes podem armazenar até 4.296 caracteres, mas conteúdo mais curto produz códigos mais limpos e fáceis de escanear.
▶Posso usar o QR code comercialmente?
Sim! QR codes gerados aqui são livres para qualquer uso, pessoal ou comercial.
▶What can I encode in a QR code?
You can encode URLs, plain text, email addresses, phone numbers, Wi-Fi credentials, vCard contact information, calendar events, and more. The maximum capacity is about 4,296 alphanumeric characters or 7,089 numeric characters.
▶Do QR codes expire?
Static QR codes (like those generated here) never expire — they permanently encode the data. However, if the QR code points to a URL, the link itself could become inactive if the website is taken down.
▶What size should my QR code be for printing?
For reliable scanning, QR codes should be at least 2 cm x 2 cm (0.8 in) for close-range scanning. For posters or signs viewed from a distance, increase the size proportionally — roughly 25 mm per meter of scanning distance.
