QR Code Generator
What is a QR code?
A QR (Quick Response) code is a two-dimensional barcode that can encode text, URLs, or other data, readable instantly by a smartphone camera. It includes built-in error correction, so it can still be scanned even if part of the code is damaged, dirty, or obscured.
When would I use this?
- Generating a QR code that links to a website, app download, or contact card for print materials.
- Creating a QR code for Wi-Fi credentials so guests can connect without typing a password.
- Quickly sharing a URL or piece of text between devices by scanning instead of typing.
How it works
The QR code is generated and rendered to a canvas entirely in your browser using a standards-compliant QR encoding library, then exported as a PNG you can download — nothing you enter is sent to a server.
