QR Code Generator

Do these QR codes expire?

No, the QR codes generated here are static. They directly encode your text or URL and will work forever as long as your link is valid. Unlike dynamic QR codes that require a service, these codes contain the data directly and don't depend on any external service.

Is it free to use?

Yes, this tool is 100% free for both personal and commercial use. No registration, no credit card, no hidden fees. Generate unlimited QR codes without any restrictions.

What file format are the QR codes?

QR codes are downloaded as PNG (Portable Network Graphics) files, which provide high quality and are compatible with all devices and platforms. PNG format ensures your QR codes remain clear and scannable at any size.

Can I customize the colors?

Yes! You can customize both the foreground color (the QR code pattern) and the background color. Choose colors that match your brand or design. However, ensure there's sufficient contrast between foreground and background colors for optimal scanning.

What size should I use for my QR code?

The recommended size depends on where you'll use it:

• Digital screens: 200-300px is usually sufficient
• Print materials: 300-500px for better quality
• Large format printing: 500-1000px for billboards or posters
• Small items: Minimum 100px, but larger is better for scanning

Will colored QR codes scan properly?

Yes, as long as there's sufficient contrast between the foreground and background colors. Dark colors on light backgrounds work best. Avoid using similar colors (like light gray on white) as this can make scanning difficult. The QR code uses high error correction (Level H) to ensure reliability even with custom colors.

What types of QR codes can I create?

Our generator supports 8 different QR code types:

• URL: Link to websites or web pages
• Text: Plain text messages or information
• Email: Pre-filled email with recipient, subject, and body
• SMS: Text message with phone number and message
• Phone: Direct dial phone number
• WiFi: Share WiFi network credentials
• YouTube: Link to specific YouTube videos
• vCard: Digital business card with contact information

Is my data secure?

Yes! All QR code generation happens entirely in your browser. Your data is never sent to our servers. The QR code is generated locally using JavaScript, ensuring complete privacy and security. We don't store, track, or have access to any of your information.

Can I use QR codes for commercial purposes?

Absolutely! There are no restrictions on commercial use. You can use the generated QR codes in marketing materials, product packaging, advertisements, business cards, or any other commercial application without any limitations.

What happens if I scan a QR code?

When you scan a QR code with your smartphone camera, the device reads the encoded data and performs the appropriate action:

• URLs open in your web browser
• Text displays as a message
• Email opens your email app with pre-filled information
• SMS opens your messaging app
• Phone numbers initiate a call
• WiFi codes connect to the network
• YouTube links open the video
• vCard codes save contact information

Do I need a special app to scan QR codes?

Most modern smartphones (iPhone and Android) have built-in QR code scanners in their camera apps. Simply open your camera app and point it at the QR code. If your device doesn't have a built-in scanner, you can download a free QR code reader app from your app store.

Can I edit a QR code after generating it?

Since these are static QR codes that encode data directly, you cannot edit them after generation. If you need to change the content, simply generate a new QR code with the updated information. The old QR code will continue to work with the original data.
