QR Code Generator
Generate high-resolution QR codes for URLs, Wi-Fi, contact cards, or any text. Free, no watermark, no signup.
Create a high-resolution QR code from a URL, Wi-Fi network, contact card, or plain text, with control over size, error correction level, and foreground/background colors. Rendering happens locally, so codes generate instantly with no watermark, no account, and no limit on how many you create. Good for print materials, business cards, restaurant menus, or event signage where you need a code you fully control and can regenerate anytime.

Common questions
What's the difference between L / M / Q / H?
Error correction level. Higher levels (H = 30%) survive more damage but produce denser codes. M is the balanced default.
Can I use the QR code commercially?
Yes. QR codes generated here are yours to use anywhere.
Can I generate a QR code for Wi-Fi login?
Yes - enter the network name and password and the QR encodes the standard Wi-Fi connection format most phone cameras recognize automatically.
Is my data uploaded to a server?
No - the QR code image is rendered entirely in your browser.
