QR Code Generator

A QR (Quick Response) code is a two-dimensional barcode that can store various types of information such as URLs, text, contact information, and more. When scanned with a smartphone camera or QR code reader app, it instantly takes the user to the encoded content.

QR codes work by encoding data into a pattern of black and white squares that can be read by optical scanners. They can store up to 4,296 alphanumeric characters and are designed to be read quickly from any angle.

Yes! CanvaFly's QR code generator is 100% free to use with no hidden costs, subscriptions, or limitations. You can generate unlimited QR codes for personal and commercial use without any watermarks or branding.

All features including logo integration, multiple QR code types, and various size options are available at no cost. We believe in providing powerful tools that are accessible to everyone.

Absolutely! Our QR code generator supports custom logo integration. Simply click the upload area and select your logo image (PNG, JPG, or GIF format). The generator automatically optimizes the logo size and placement to maintain QR code scannability.

For best results, use a square logo with high contrast. The logo will be placed in the center of your QR code with appropriate padding to ensure reliable scanning.

Our generator supports multiple QR code types:

• URL: Direct users to any website
• Text: Display plain text messages
• Email: Pre-fill email address, subject, and body
• Phone: Initiate phone calls
• SMS: Send text messages with pre-filled content
• WiFi: Share WiFi credentials for easy connection

Each type is optimized for its specific use case and will trigger the appropriate action when scanned.

The optimal size depends on your use case and scanning distance:

• 200px: Business cards, labels (minimum 2cm x 2cm print size)
• 300px: Flyers, brochures, restaurant menus
• 400px: Posters, signage, product packaging
• 500px: Large format printing, billboards

As a general rule, maintain a 10:1 ratio between scanning distance and QR code size. Always test your printed QR codes before mass production.

No, QR codes generated with our tool never expire. They are static QR codes that contain the information directly in the code pattern itself, making them permanent and reliable.

However, if you create a QR code that links to a website and that website goes offline or the URL changes, the QR code will still scan but lead to an error page. The QR code itself remains functional forever.

Yes, your data is completely safe and private. All QR code generation happens locally in your browser using JavaScript. We don't send your data to any servers or store any information you input.

Once you close the page or refresh it, all data is cleared from memory. We don't use cookies to track your QR code content, and we don't require any registration or personal information to use the service.

Yes! All QR codes generated with CanvaFly are free for both personal and commercial use. You can use them on:

• Business cards and marketing materials

There are no licensing fees, attribution requirements, or usage restrictions.

To test your QR code:

1. Use your smartphone's built-in camera app (most modern phones support QR scanning)
2. Point the camera at the QR code from about 6-12 inches away
3. Wait for the notification or link to appear
4. Tap to execute the encoded action

We recommend testing with multiple devices and QR scanner apps to ensure compatibility. Also test under different lighting conditions if you're planning to use the QR code in various environments.
