QR Code Generator

URLs, Wi-Fi and text as QR codes.

Special characters \ ; , : " are escaped with a backslash, as the Wi-Fi QR format requires. The password is part of the image: anyone who scans it can join.

Use the international format with a leading +, so it dials from any country.

Options

Higher error correction survives damage or a logo on top, at the cost of a denser code. Scanners expect a quiet zone of 4 modules.

About the QR Code Generator


This tool turns a URL, plain text, Wi-Fi login, email, phone number or SMS into a QR code in your browser. It picks the smallest QR version that fits at your error correction level, then draws a sharp PNG at the exact size you set and builds an SVG from a single path that scales without blurring.


Wi-Fi codes use the WIFI:T:WPA;S:<network>;P:<password>;H:false;; format that iPhone and Android cameras read, with \, ;, ,, : and " escaped by a backslash. Email codes become mailto: links with an encoded subject and body, phone codes tel: and SMS codes SMSTO:. It shows the exact encoded text and warns when the colors are too close or inverted to scan, or the quiet zone is too thin.

Common questions


Which error correction level should I use?


M is a good default. Use Q or H if the code will be printed on rough surfaces or a logo will cover part of it; higher levels make the code denser.


Do QR codes expire?


No. The content is stored in the image itself, so a code works as long as the URL it points to does.


How big should a printed QR code be?


A common rule of thumb is a width of at least a tenth of the scanning distance, and never less than 2 cm including the quiet zone.
