Free QR Code Generator Online
Our QR code generator lets you create QR codes quickly and free, right in your browser. Just enter text, a URL, phone number or any data, and the tool will generate a ready-to-download QR code as PNG. A QR code (Quick Response) is a two-dimensional barcode that stores information in a black-and-white pattern. QR codes can be read by smartphone cameras and barcode scanners, making them ideal for sharing information fast.

How to create effective QR codes?
- Right size - A QR code should be at least 2×2 cm for print. For billboards use at least 256×256 px.
- High contrast - Keep a dark pattern on a light background. Avoid low colour contrast.
- Test before printing - Always scan the code with different devices before printing.
- Short URLs - The less data, the simpler and more readable the QR code.
- Quiet zone - Leave an empty margin around the code so scanners can read it easily.
Frequently asked questions
Do QR codes expire?
Static QR codes (like those from our tool) never expire. They contain data directly in the code, so they work as long as the encoded data is valid.
What is the maximum QR code capacity?
A QR code can store up to 4,296 alphanumeric characters, 7,089 digits or 2,953 bytes of binary data. Shorter data produces a simpler, easier-to-scan code.
Is the generator free?
Yes, our QR code generator is completely free with no limits. You can create any number of QR codes without registering.
Can I use QR codes commercially?
Of course! You can use the generated QR codes for any purpose - personal or commercial, in print or digital.
Our QR code generator runs entirely in your browser. Your data is not sent to any server - generation happens locally on your device.
