Passo 1 - abra a ferramenta

Acesse o Scanner de QR Code. Nada precisa ser instalado ou autenticado antes de comecar.

Passo 2 - forneca a entrada

Quando o codigo contem um link, a ferramenta mostra o URL exato como um link clicavel ANTES de voce visita-lo - uma forma facil de verificar um QR code suspeito de phishing.

Passo 3 - obtenha o resultado

Copie o valor decodificado com um clique - util para senhas de wifi, numeros de serie, strings de cupom ou referencias de pagamento longas.

Fotos de alta resolucao do celular funcionam - imagens grandes sao reduzidas automaticamente antes da decodificacao, entao ate uma foto de 12MP decodifica rapidamente.

Perguntas frequentes

O que acontece se o QR code estiver borrado?

A ferramenta orienta voce a tentar novamente com uma imagem mais clara ou maior em vez de falhar silenciosamente.
