Email QR Code Generator

An email QR Code Generator turns a recipient address, subject, and message into a QR code that opens a phone's mail composer with those fields already filled in. Instead of dictating an address and asking someone to type it correctly, you print or display the code; they point a camera at it, tap the prompt, and a new email to you appears ready to send. It removes the transcription errors that turn a printed address into a bounced message.

The code encodes a mailto: link, the same URI scheme a mailto hyperlink uses, defined in RFC 6068. The recipient sits in the link path and the subject, body, CC, and BCC become percent-encoded query parameters, so a subject line with spaces or an ampersand survives intact. That string is then encoded as a QR matrix with Reed-Solomon error correction following ISO/IEC 18004, the specification every scanner app implements, which is why the result works with the built-in camera on any modern phone rather than needing a special reader.

Everything runs inside your browser. The address and message you enter are never uploaded, logged, or attached to a scan-tracking dashboard - the encoding happens in JavaScript on your device, and the tool keeps working with the network unplugged once the page has loaded. The QR code it produces is static, meaning the mailto link lives in the image itself with no short URL in the middle that could expire or be switched off. It is built for business cards, email signatures, flyers, product packaging, and event signage where you want to make getting in touch a single scan.
