QR Code Generator

Create QR codes for URLs, text, WiFi, vCard free

What is the QR Code Generator?

The qr code generator works like this: it renders high-resolution QR codes for URLs, plain text, Wi-Fi credentials, vCard contacts and calendar events, with error-correction level control. Everything happens on your device - the input never leaves your tab unless the tool clearly states it performs a server-side lookup.

How to use the QR Code Generator

1. Set the options that matter for your output (length, style, colors, counts).
2. Generate - results appear instantly.
3. Regenerate until you like what you see.
4. Copy or download the result.

Frequently asked questions

Which error correction level should I pick?

M (15%) for clean digital use; H (30%) when printing outdoors, adding a logo overlay, or expecting scuffs.

Do QR codes expire?

The code itself never expires, but whatever it points at might. Print codes that point to stable URLs.

Why does my QR code look so dense?

Density grows with data volume and error-correction level - shortening the content or dropping to level L visibly opens the pattern up, and the preview shows the change instantly.

Can one QR code hold Wi-Fi login details?

Yes - choose the Wi-Fi type, enter the network name and password, and phones scanning it can join directly instead of typing the password.

How much text fits in one code?

Roughly 4,000 characters maximum at low correction, but codes stay comfortably scannable under about 1,000 - for longer content encode a short link instead.
