QR Code Generator

A QR code encodes text as a grid of black and white squares that a camera can decode back into the original data, and this tool generates one live as you type — any URL, plain text, Wi-Fi credentials string, or contact card format renders instantly at 256x256 pixels. The encoding uses Reed-Solomon error correction, which is why QR codes still scan correctly even when part of the code is scratched, obscured by a logo, or photographed at an angle: redundant data is woven into the grid so a scanner can reconstruct missing or misread modules.

Data capacity depends on both the content and the QR version (grid size) the encoder selects automatically — short URLs fit comfortably in a small, easy-to-scan grid, while long blocks of text push the encoder to a denser, larger grid with smaller modules that are more sensitive to print size and camera distance. If your input is too long to encode at all, the tool reports that generation failed rather than silently truncating your text.

The generated code downloads as a PNG, suitable for printing on packaging, signage, or business cards, or embedding directly in a document.

A QR code stores data as a grid of modules, with Reed-Solomon error correction that lets it scan even when part of it is damaged or covered. Longer content needs a denser grid, which is harder to scan at small sizes.

A QR code holds only the text you give it, with no tracking. A static code never expires, but if the URL it points to changes, the code will go to the old address. Use a short, stable URL for printed material.
