Select the content type
Choose what your QR code should contain — URL, plain text, Wi-Fi credentials, vCard contact, email, phone number, or SMS. Each type has specific fields optimized for that data.
Enter your data
Fill in the required fields for your chosen content type. For URLs, enter the full address including https://. For Wi-Fi, enter the network name, password, and encryption type.
Customize the appearance
Set the foreground and background colors, add a logo or image overlay, and choose the dot style (square, rounded, or dots). Keep sufficient contrast for reliable scanning.
Set error correction level
Choose from Low (7%), Medium (15%), Quartile (25%), or High (30%) error correction. Higher levels make the QR code more resilient to damage but increase density. Use High when adding a logo overlay.
Download the QR code
Download as PNG for digital use or SVG for print materials where you need scalability. The tool generates high-resolution output suitable for posters, business cards, and packaging.
Pro Tips
- *Always use a URL shortener for long URLs — shorter data means less dense QR codes that scan more reliably.
- *Test your QR code on multiple devices before printing — scan distance varies by phone camera quality.
- *Use High error correction when adding a logo overlay to ensure the code remains scannable.
- *For print, export as SVG and ensure a quiet zone (white border) of at least 4 modules around the code.
