What Is a QR Code Generator?
A QR (Quick Response) code is a two-dimensional barcode that stores text — a URL, a message, contact details — in a grid of black and white squares that a phone camera or barcode scanner can read in an instant. This tool builds a QR code from scratch, directly in your browser, using the same encoding rules (data encoding, error-correction, module placement) defined by the QR code standard.
Because it runs entirely client-side with no server round trip, whatever you type — even a private link or message — is never transmitted anywhere; the QR image is rendered and can be downloaded straight from your browser.

Use a URL Shortener for Long Links
Since capacity is limited to roughly 106 characters, shorten very long URLs first for a cleaner, more scannable code.
