Step-by-Step Guide
Open QRCodeGen.ai
Visit qrcodegen.ai in any modern browser. No download or installation needed — the tool runs entirely in your browser. No account or signup required.
Select your QR code type
Choose what kind of data to encode: URL (website link), WiFi (network credentials), vCard (contact card), Email, Phone, SMS, or plain Text. URL is the most common choice for marketing and sharing.
Enter your content
Fill in the data fields for your chosen type. For URL, paste your website link. For WiFi, enter your network name (SSID), password, and security type (WPA/WPA2). For vCard, enter name, phone, email, company, and address. Keep data concise — shorter content creates simpler, easier-to-scan QR codes.
Customize foreground and background colors
Click the color pickers to set your brand colors. The foreground color applies to the QR code dots; the background fills the area behind them. Maintain high contrast — dark dots on a light background scans best. Avoid low-contrast combinations like yellow on white or light gray on white.
Choose a dot shape
Select from five dot shape options: Square (classic, traditional), Rounded (modern, soft), Dots (circular, stylish), Classy (elegant, refined), or Classy Rounded (elegant with soft edges). Each shape changes the personality of your QR code while maintaining scannability.
Customize corner eye shapes
The three large squares in the corners of a QR code (called 'eyes' or 'finder patterns') can be customized independently. Choose from different eye shapes to add another layer of design to your QR code.
Upload your logo (optional)
Click the logo upload area and select an image file. Your logo will be placed in the center of the QR code. PNG with transparent background works best. Keep the logo simple and ensure it doesn't cover more than 30% of the QR code area. QRCodeGen.ai handles sizing automatically.
Preview and test
The QR code updates in real time as you make changes. Test it by opening your phone's camera and scanning the preview on your screen. Verify it links to the correct destination or displays the right data. Always test before printing.
Choose export format and download
Select your export format: PNG (raster, up to 2048×2048 pixels — great for digital use and standard printing), SVG (vector, scales infinitely — best for professional printing, large signage, and business cards), or WebP (smaller file for web). Choose your resolution and click Download.
Tips for Better QR Codes
Keep Data Short
Shorter URLs and text create simpler QR codes that scan faster and more reliably. Use URL shorteners for long links.
High Contrast
Dark foreground on light background works best. The scanner needs clear contrast to read the pattern.
Test Before Printing
Always scan your QR code with multiple devices before sending to print. Check different lighting conditions.
Size Matters
Minimum 2cm × 2cm for print. For scanning from distance, increase size proportionally — about 1cm per 10cm of distance.
Add Context
Include a call-to-action near the QR code: 'Scan for menu', 'Scan to connect', 'Scan to save contact'.
Use SVG for Print
Vector SVG files scale to any size without quality loss. Always use SVG for professional printing.
Frequently Asked Questions
How long does it take to create an AI QR code?
Under a minute. QRCodeGen.ai generates QR codes in real time — you see the result instantly as you customize. The entire process from opening the page to downloading takes 30-60 seconds.
Do I need design skills to create a custom QR code?
No. QRCodeGen.ai provides simple controls — color pickers, shape selectors, and a logo upload button. If you can pick a color and upload a file, you can create a professional-looking custom QR code.
What if my QR code doesn't scan after customization?
This usually happens when contrast is too low (e.g., light colors on a light background) or the logo covers too much of the QR code. Try increasing the contrast between foreground and background colors, and ensure your logo covers less than 30% of the QR code area.
Can I create AI QR codes on my phone?
Yes! QRCodeGen.ai is fully responsive and works on mobile browsers. You can create, customize, and download QR codes directly from your phone or tablet.
What's the best format for printing QR codes?
SVG (vector) is best for print. It scales to any size without losing quality — perfect for business cards, posters, and signage. For standard digital use, PNG at 1024×1024 or higher works well.
