About this QR code generator
A QR code (short for "quick response" code) is the square barcode you scan with a phone camera to open a link or read some text. This tool turns whatever you type — a website address, a Wi-Fi note, contact details, or any short message — into a QR code you can download and print. Everything is built right in your browser with a small built-in encoder, so your text is never uploaded or stored anywhere. Choose a larger module size for a sharper, bigger image, and raise the error correction level if the code might get smudged or partly covered.
Frequently asked questions
- What is a QR code?
- A QR code is a square barcode that holds text or a web link. When you point a phone camera at it, the phone reads the code and opens the link or shows the text.
- Is my text or link uploaded anywhere?
- No. The QR code is built entirely in your browser using a small built-in encoder, so whatever you type never leaves your device.
- What does the error correction setting do?
- Error correction (levels L, M, Q and H) lets a QR code still be read even if part of it is dirty or damaged. Higher levels survive more damage but make the code denser. Medium (M) is a good default.
