Free QR Code Generator

Generate custom QR codes for URLs, text, and WiFi instantly in your browser.

Error correction

How it works

  1. Enter the URL or text you want to encode.
  2. Pick an error-correction level — higher levels survive more damage.
  3. Download the QR code as a scalable SVG or a PNG image.
Privacy & Processing: QR codes are generated entirely in your browser. Your text, links, and WiFi details are never sent to any server.

Frequently Asked Questions

Do QR codes expire?

No. These are static QR codes — the data is encoded in the image itself, so they work forever.

Is my data sent anywhere?

No. Generation happens locally in your browser, so sensitive payloads such as WiFi passwords never leave your device.

What does error correction do?

Higher levels add redundancy so a code still scans when partly damaged or covered, at the cost of a denser image.
