What is QR Code Generator?

A QR code generator creates Quick Response (QR) codes that can be scanned by smartphone cameras to quickly access URLs, text, or other data. QR codes are widely used in marketing, print materials, business cards, and event promotions to bridge offline and online experiences.

How to Use QR Code Generator

Enter a URL, text, or any data in the input field. The QR code is generated instantly in real time. Adjust the size and error correction level if needed. Click Download PNG to save the QR code image. You can also customize the foreground and background colors.

How QR Code Generator Works

Enter your data (URL, text, etc.) and the tool encodes it into a QR code matrix using standard QR code algorithms. The QR code is rendered on an HTML Canvas element in real time. You can customize colors, size, and error correction level, then download the result as a PNG image.

Common Use Cases

  • Create QR codes for website URLs on print materials
  • Generate scannable links for business cards and flyers
  • Share WiFi credentials or contact information via QR codes

Frequently Asked Questions

What data can I put in a QR code?

QR codes can encode URLs, plain text, email addresses, phone numbers, WiFi credentials, vCard contacts, and more. URLs are the most common use case. The maximum data capacity depends on the error correction level and data type.

What is QR code error correction?

Error correction allows a QR code to be scanned even if part of it is damaged or obscured. There are four levels: L (7%), M (15%), Q (25%), and H (30%). Higher correction means the QR code can tolerate more damage but requires a denser pattern.

What size should a QR code be for printing?

A QR code should be at least 2cm x 2cm (0.8in x 0.8in) for close-range scanning. For posters or billboards, use the rule of thumb: the QR code should be 1/10th of the scanning distance (e.g., 10cm for 1 meter distance).

Can QR codes expire?

Static QR codes (like those generated by this tool) never expire because the data is encoded directly in the image. Dynamic QR codes (which redirect through a service) can expire if the service is discontinued or the subscription lapses.
