QR Code Generator is a browser-based tool on 24Toolkit. Generate QR codes for links, WiFi credentials, contact cards, or plain text. Customize colors, add a logo, and download as PNG or SVG. Our QR Code Generator is a professional-grade utility for creating scannable Quick Response codes from any text, URL, email address, phone number, or SMS template. QR codes have become ubiquitous in modern marketing, payments, authentication, and information sharing, offering a fast bridge between the physical and digital worlds. This tool generates QR codes with high error correction (Level H), meaning up to 30% of the code can be damaged or obscured while remaining scannable. You can customize the output size from 128px to 512px to suit anything from business cards to large posters. QR codes are generated client-side in JavaScript, so the URLs, contact details, or other data you encode are never sent to an external service.

FAQ
What types of content can I encode in a QR code?
You can encode virtually any text-based content: URLs, plain text messages, email addresses (mailto:), phone numbers (tel:), SMS messages (sms:), WiFi credentials, vCard contact information, and more.
Why should I use high error correction?
High error correction (Level H) allows up to 30% of the QR code to be damaged, dirty, or even covered by a logo while still remaining scannable. This is ideal for printed materials that may experience wear.
Is my data safe when generating QR codes?
Yes. QR code generation runs entirely in client-side JavaScript. The URLs, contact details, or text you encode are processed in-browser and never sent to any external service. The generated image exists only in your browser until you download it.
