QR Code Generator

A QR code generator that wants nothing from you. No account, no upload, no shortener sitting between the code and its destination. The encoder is written into this page, so the symbol on screen is built from your text and nothing else.

• Free foreground and background colours, with a transparent background as the default, exported as PNG or SVG.
• The error-correction slider is the interesting control, so the tool shows what it does: which modules carry your data and which carry redundancy.
• Cover part of the symbol and the tool counts damaged codewords against the actual correction budget, instead of quoting the usual marketing percentage.
• Eight module shapes, from plain squares to a tangle that joins neighbouring modules at random without ever closing a loop, to a mode that joins only the places where the modules happen to spell a Korean letter. Each carries the resolution it costs, measured against an independent decoder rather than asserted.
• The eighth shape animates, and the code stays readable while it does. Small snakes crawl along the dark modules, born and dying on a loop that closes exactly, downloadable as a GIF or an animated SVG. Other tools sell a still code in front of a moving background; here the code itself moves, because only the connections between modules change and never the modules.
• Presets for WiFi credentials, contact cards, email, SMS, geo coordinates and phone numbers.
