PIX is the Central Bank of Brazil's instant-payment system, and every bank and payment app in Brazil reads the same underlying format for a PIX QR code — officially called the "BR Code," built on the international EMVCo QR standard.
This generator builds that exact format for you: enter your PIX key (an email, phone number, CPF/CNPJ, or a random key your bank issued), your name, your city, and an optional amount. The tool assembles the proper tag-length-value payload — including the checksum every BR Code needs — the same way a bank's own system would, but entirely in your browser.
Leaving the amount blank produces a code the payer can use to send any amount; filling it in fixes the amount for that specific code, useful for a one-off invoice or a fixed-price sale.
