QR Code Generator
Generate QR codes for URLs, text, email, phone, WiFi, and more
How to Use
Select your desired data type from the dropdown menu, choosing between URL, Text, Email, Phone, WiFi, or SMS options. Each type is optimized for specific use cases and automatically formats the QR code content according to industry standards to ensure maximum compatibility with QR code scanners and mobile devices.
Enter your content data in the appropriate input field based on your selected type. For URLs, input the complete web address including http:// or https://. For text, enter any message up to the QR code capacity limits. For email, provide the recipient address and optional subject and message fields.
Configure WiFi settings if selected by entering the network name (SSID), password, and security type (WPA, WEP, or no password). The tool automatically formats this information into the standard WiFi QR code format that allows users to connect instantly by scanning the code with their mobile devices.
For phone and SMS types, enter the phone number in international format when possible (including country code) and any optional message content. This creates QR codes that can trigger direct phone calls or pre-filled SMS messages when scanned, streamlining communication workflows.
Adjust the QR code size using the size selector to match your intended use case. Smaller sizes work well for business cards and printed materials, while larger sizes ensure better scanning reliability for posters, signage, and situations where scanning distance may be greater.
Set the error correction level from Low (7%) to High (30%) based on your environmental requirements. Higher error correction allows the QR code to remain scannable even if partially damaged, obscured, or printed on textured surfaces, while lower levels allow for smaller, cleaner codes.
Click the 'Generate QR Code' button to create your custom QR code. The tool processes your input data and generates a high-quality QR code image that appears instantly in the preview area, ready for immediate use or further customization.
Download your QR code by right-clicking the generated image and selecting 'Save image as' or use the copy function to paste it directly into documents, presentations, or design applications. The generated QR code maintains high resolution suitable for both digital and print applications.
Pro Tips
- Test your QR codes with multiple devices and scanning apps before final deployment to ensure compatibility across different platforms and scanning conditions, as some older devices may have limitations with certain QR code types or sizes.
- For URLs, use shortened links when possible to reduce QR code complexity and improve scanning reliability, especially for complex URLs with many parameters or very long domain names that create dense QR code patterns.
- Choose higher error correction levels for QR codes that will be displayed outdoors, printed on textured materials, or used in environments where the code might become dirty or partially obscured during normal use.
- When creating QR codes for business cards or small printed materials, test the minimum size requirements for reliable scanning by printing test samples and verifying readability with various smartphone cameras and scanning apps.
- For WiFi QR codes, ensure your network name and password are exactly correct as even small typos will prevent successful connection, and consider using guest networks for public QR codes to maintain security.
- Include a small text description near your QR code explaining what it contains (e.g., 'Scan for website', 'WiFi login', 'Contact info') to encourage scanning and provide context for users who encounter the code.
- Keep QR code content concise when possible, as simpler codes are faster to scan, more reliable across devices, and create cleaner visual patterns that integrate better with design layouts and printed materials.

Frequently Asked Questions
What types of data can I encode in QR codes and what are the capacity limits?
QR codes can store various data types including URLs (up to 2,953 bytes), plain text (up to 4,296 characters), email addresses with subjects and messages, phone numbers, WiFi credentials, and SMS messages. The actual capacity depends on the character type used - numeric data allows more characters than alphanumeric or binary data. Higher error correction levels reduce capacity but improve scanning reliability.
How do error correction levels affect QR code performance and when should I use each level?
Error correction levels determine how much damage a QR code can sustain while remaining scannable. Low (7%) is suitable for clean environments and digital displays. Medium (15%) works well for most print applications. Quartile (25%) is recommended for outdoor use or textured surfaces. High (30%) is ideal for harsh environments, curved surfaces, or situations where partial obstruction is likely.
What's the optimal size for QR codes in different applications?
QR code size depends on scanning distance and use case. For business cards, 0.5-1 inch works well. Posters and signage need 2-4 inches for comfortable scanning from 3-6 feet away. The general rule is 1 inch of QR code size per 3 feet of scanning distance. Digital displays can use smaller sizes since scanning distance is typically closer.
Are QR codes secure and what privacy considerations should I be aware of?
QR codes themselves are not encrypted and can be read by anyone with a scanner. Avoid encoding sensitive information directly. For security, link to secure websites (HTTPS), use temporary or one-time URLs when possible, and consider using password-protected content. Users should be cautious about scanning unknown QR codes as they can link to malicious websites.
How can I ensure my QR codes work across different devices and scanning apps?
Test QR codes with multiple devices (iOS, Android) and scanning apps before deployment. Use standard data formats, maintain good contrast (dark on light background), ensure adequate quiet zones around the code, and avoid excessive customization that might interfere with scanning algorithms. Popular apps include built-in camera apps and dedicated QR scanners.
Can I customize QR code appearance and colors while maintaining functionality?
Basic customization is possible but requires caution. You can change colors as long as there's sufficient contrast (dark pattern on light background). Avoid light colors on dark backgrounds, gradients, or complex patterns. Adding logos in the center is possible due to error correction, but keep them small (10-20% of code area) and test thoroughly across devices.
What's the difference between static and dynamic QR codes?
Static QR codes contain the actual data encoded directly in the pattern and cannot be changed once created. Dynamic QR codes contain a short URL that redirects to the actual content, allowing you to update the destination without reprinting the code. Our generator creates static codes, which are ideal for permanent content and don't require ongoing server maintenance.
How do I create QR codes for WiFi networks and what security types are supported?
Select WiFi type, enter your network name (SSID), password, and security type. Supported security types include WPA/WPA2 (most common), WEP (legacy), and open networks (no password). The generated code allows users to connect automatically when scanned. Ensure your network name and password are exactly correct, including case sensitivity.
What should I do if my QR code isn't scanning properly?
Check several factors: ensure sufficient size for scanning distance, verify adequate contrast, confirm the code isn't damaged or distorted, test with different scanning apps and devices, and make sure there's adequate lighting. For print codes, verify print quality and avoid glossy surfaces that create glare. Consider regenerating with higher error correction if problems persist.
