What is QR Code Generator?

QR Code Generator is a free browser-based tool that creates scannable QR codes for URLs, plain text, WiFi credentials, contact cards (vCard) and more. QR codes are generated instantly in your browser and can be downloaded as PNG or SVG files with no watermarks and no file size limits.

QR codes encode data as a 2D matrix of black and white squares that any smartphone camera can read. The error correction level controls how much of the code can be damaged or obscured while still scanning correctly. Level L (7% recovery) creates smaller, simpler codes. Level H (30% recovery) creates larger codes that scan reliably even with logos overlaid in the center.

Common use cases include linking print materials to websites, encoding WiFi passwords so guests can connect by scanning instead of typing, creating contact cards for business cards, directing shoppers to product pages, and adding deep links in packaging. QR codes for URLs should link to HTTPS pages to avoid browser security warnings on modern phones.

Frequently asked questions

What can a QR code contain?
URLs, plain text, email addresses, phone numbers, SMS messages, WiFi credentials, and contact card data in vCard format are all supported.
What resolution is the downloaded PNG?
The QR code is downloaded as a high-resolution PNG suitable for both digital use and print. At minimum 2cm print size, scanning reliability is very high.
Is there a URL length limit?
Longer URLs create more complex QR codes with smaller individual squares. Very long URLs still work but may scan more slowly. Use a URL shortener for very long URLs to produce a simpler, more reliable code.
Can I customize the QR code colors?
Standard black on white is generated by default. High contrast between foreground and background is important for reliable scanning.
Does it work offline?
Yes.
Do I need an account or pay anything?
No. QR code generation is completely free with no account required.
