Step-by-Step Instructions

Choose Your QR Code Type

First, decide what type of QR code you need. The most common types are:

URL/Link: Send people to a website, menu, or landing page
WiFi: Let guests connect to your network instantly
Contact Card (vCard): Share your complete contact information
Email: Pre-fill an email message
Phone: Initiate a call or text message
SMS: Send a pre-written text

Pro Tip: Most businesses start with URL QR codes. They're the most versatile and work for websites, PDFs, menus, and any online content.

Enter Your Information

Go to a QR code generator (we recommend qrfrog for its simplicity and free features). Enter your information in the appropriate field:

For URLs: Paste the full web address (including https://)
For WiFi: Enter your network name (SSID) and password
For contacts: Fill in name, phone, email, and other details

Important: Double-check your information before generating. Typos in QR codes can't be fixed without reprinting.

Customize Your Design (Optional)

Most generators let you customize your QR code's appearance:

Colors: Match your brand colors (keep good contrast)
Logo: Add your logo in the center (ensure it doesn't block key areas)
Shape: Choose square or rounded corners
Frame: Add a border with a "Scan Me" call-to-action

✓ Do: High Contrast

Dark QR codes on light backgrounds scan best. Black and white is most reliable.

✓ Do: Test Before Printing

Always scan your code with multiple devices before finalizing.

✗ Don't: Invert Colors

White QR codes on dark backgrounds often fail to scan.

✗ Don't: Over-Customize

Too much design can make codes unscannable. Keep it simple.

Generate and Download

Click the "Generate" or "Create" button. Your QR code will appear instantly. Now download it in the right format:

PNG: Best for digital use, social media, and websites
SVG: Best for print. It scales to any size without losing quality
PDF: Ideal for professional printing and large formats

File Size Tip: For print, download at least 1000x1000px or use SVG format. For digital, 400x400px is usually sufficient.

Test Your QR Code

Before using your code publicly, test it thoroughly:

Scan with your phone's camera (iPhone or Android)
Try different distances (6 inches to 2 feet)
Test in different lighting conditions
Verify it leads to the correct destination
Test on multiple devices if possible

Troubleshooting: If your code doesn't scan, check that it's not too small, has sufficient contrast, and isn't pixelated.

Best Practices for QR Code Creation

Size Guidelines

Minimum size: 2 x 2 cm (0.8 x 0.8 inches) for close-up scanning
Business cards: 3 x 3 cm (1.2 x 1.2 inches)
Posters: 5 x 5 cm (2 x 2 inches) or larger
Billboards: Scale proportionally based on viewing distance

Error Correction Levels

QR codes have built-in error correction that lets them work even if damaged:

Low (L): 7% can be restored-good for clean digital use
Medium (M): 15% can be restored-best for most print applications
High (H): 30% can be restored-ideal for codes with logos or heavy use

Where to Place QR Codes

Location matters as much as the code itself:

✓ Good locations: Business cards, product packaging, receipts, table tents, flyers
✗ Bad locations: Moving vehicles (hard to scan), areas with no cell service, behind reflective glass
✓ Pro placement: Eye level, good lighting, with a clear call-to-action like "Scan for menu"
