Everything you need to know about creating professional QR codes
QR Generator is a powerful, free tool for creating custom QR codes with advanced features. Whether you need a simple QR code for a website URL or a complex one with a custom logo and colors, our tool provides all the options you need.
All QR code generation happens directly in your browser - no data is sent to any server, ensuring complete privacy and security for your information.
Choose from URL, plain text, email, phone, SMS, WiFi, or vCard. Each type has specific input fields optimized for that data format.
Fill in the required information based on your selected type. The QR code will update in real-time as you type.
Adjust colors, size, margin, and error correction level. Upload a logo and customize its position, size, opacity, border, and background.
Scan the preview with your phone to verify it works correctly, then download in your preferred format (PNG, JPEG, or SVG).
Error correction allows QR codes to be read even if they're partially damaged or obscured. Higher levels allow for larger logos but create more complex codes.
Best for simple text QR codes without logos. Smallest code size.
Good balance for QR codes with small logos (<20% size).
Recommended for QR codes with medium logos (20-30% size).
Best for large logos (30-40% size). Maximum error resilience.
Add your brand's logo to make QR codes more recognizable and professional.
Adjust logo size from 10% to 50% of QR code. Keep under 30% for best scanability.
Place logo anywhere on the QR code using X and Y position sliders (default: center).
Add borders, background colors, adjust opacity, and set corner radius for rounded edges.
Link to websites. Automatically adds https:// if missing. Perfect for marketing and sharing links.
Any text content. Great for messages, codes, or information that doesn't need special formatting.
Opens email client with pre-filled recipient, subject, and body. Perfect for contact information.
Direct dial or send pre-filled SMS messages. Great for customer support and quick contact.
Share WiFi credentials instantly. Supports WPA, WPA2, WEP, and open networks. Great for offices and cafes.
Share complete contact information that can be saved directly to phone contacts. Includes name, phone, email, and more.
Customize foreground and background colors to match your brand. Important considerations:
Contrast is crucial: Ensure high contrast between foreground and background for reliable scanning.
Dark on light works best: Traditional black on white provides the most reliable scanning.
Lossless format with transparency support. Best for web and digital use. Multiple resolutions available.
Compressed format with smaller file size. Good for print when transparency isn't needed.
Vector format that scales infinitely. Perfect for large prints and professional designs. Note: Logos not included in SVG.
Yes! All QR code generation happens locally in your browser. No data is ever sent to any server.
Absolutely! The QR codes you generate are yours to use however you like, including commercial purposes.
Common issues: insufficient contrast between colors, logo too large, low error correction with a logo, or QR code printed too small. Try increasing contrast, reducing logo size, or using higher error correction.
QR codes can hold up to 2,953 bytes with high error correction. However, more data creates denser codes that are harder to scan, especially at small sizes.
No, QR codes themselves never expire. However, if your QR code links to a URL, that website could go offline.
