QR Code Generator

Turn any text or link into a QR code and download it as a PNG. Everything runs in your browser — nothing is uploaded.

Error correction

How it works

A QR code is a two-dimensional barcode that stores text — most often a URL — as a grid of black and white squares a camera can read. Type your content, choose an error-correction level, and the code is drawn instantly on a canvas you can download as a PNG. The whole thing happens locally in your browser, so your data never leaves your device.

Error correction adds redundancy so the code still scans when partly damaged or covered: Low adds about 7%, Medium 15%, Quartile 25% and High 30%. Higher levels make the code denser but more robust — handy if you plan to print it or place a logo over the centre.

Examples

  • Encode a website URL so people can open it by scanning.
  • Higher error correction survives smudges, folds and logos.
  • Everything is generated locally — nothing is uploaded.

Frequently asked questions

What can I put in a QR code?
Any text: a URL, phone number, email, Wi-Fi details, plain message and more. URLs are the most common use.
What is error correction?
Redundant data that lets a code still scan when partly damaged. Levels range from Low (~7%) to High (~30%) recovery.
Is my data uploaded anywhere?
No. The QR code is generated entirely in your browser, so the content you type never leaves your device.
Can I print the QR code?
Yes. Download the PNG and print it at any size. Use a higher error-correction level for print so scuffs don't stop it scanning.
