QR Code Generator Guide: Create Custom QR Codes

What Are QR Codes?

QR (Quick Response) codes are two-dimensional barcodes that store information readable by smartphones and dedicated scanners. Invented in 1994 for tracking automotive parts, QR codes have evolved into versatile tools for marketing, contactless payments, information sharing, and seamless digital experiences.

Why QR codes are everywhere in 2025:

• Universal smartphone support: Every modern phone has built-in QR scanning
• Contactless convenience: No typing URLs or searching required
• Versatile applications: Links, contact info, WiFi passwords, payments, and more
• Bridge physical and digital: Connect printed materials to online content instantly
• Trackable and measurable: Monitor scan rates and engagement

Common QR Code Use Cases

How to Create QR Codes

Using FastTools QR Generator makes creating custom QR codes simple:

Step 1: Choose QR Code Type

Select the type of information you want to encode:

• URL: Website links, landing pages, online menus
• Text: Plain text messages, instructions, quotes
• Email: Pre-filled email with recipient, subject, and message
• Phone: One-tap calling to your number
• SMS: Pre-filled text message
• WiFi: Network credentials for automatic connection
• vCard: Complete contact information

Step 2: Enter Your Data

Input the information specific to your chosen type. For example:

• URL: https://your-website.com (include https://)
• Email: recipient@example.com with optional subject/message
• WiFi: Network name (SSID), password, and security type
• vCard: Name, phone, email, address, company, website

Step 3: Customize Appearance

Personalize your QR code design:

• Size: Larger codes scan more reliably (minimum 2cm x 2cm recommended)
• Color: Customize foreground and background colors (maintain high contrast)
• Error correction: Higher levels allow scanning even if code is damaged
• Quiet zone: White border around code improves scanning

Step 4: Download and Use

Generate your QR code and download in your preferred format:

• PNG: Best for digital use (websites, presentations, social media)
• SVG: Vector format for print (scales infinitely without quality loss)
• High resolution: Use larger sizes (1000x1000px+) for professional print

QR Code Design Best Practices

1. Maintain High Contrast

QR codes rely on contrast between dark and light areas:

• Classic: Black on white (most reliable)
• Branded: Dark brand color on light background
• Avoid: Light colors on light backgrounds, or similar tones
• Test: Always test custom colors to ensure scannability

2. Size and Resolution

Appropriate sizing ensures reliable scanning:

3. Error Correction Levels

QR codes have built-in redundancy for damage tolerance:

• Low (7%): Smallest code, use only for pristine conditions
• Medium (15%): Good balance, recommended for most uses
• Quartile (25%): Better durability, slightly larger
• High (30%): Maximum durability, allows logo placement, largest size

4. Placement and Context

Strategic placement maximizes scans:

• Place at eye level when possible
• Ensure adequate lighting for scanning
• Avoid curved or textured surfaces
• Include clear call-to-action ("Scan for menu", "Scan to download")
• Consider viewing distance when sizing

Marketing Applications

Restaurant Menus

Replace printed menus with QR codes:

• Place codes on tables, windows, or tent cards
• Link to digital menu (PDF or web page)
• Easy updates without reprinting
• Contactless and hygienic
• Track menu views and popular items

Product Packaging

Enhance customer experience:

• Link to assembly instructions or user manuals
• Product registration and warranty activation
• Video demonstrations and tutorials
• Customer reviews and testimonials
• Cross-selling related products

Event Marketing

Streamline event management:

• Event registration and ticket sales
• Add to calendar with event details
• Venue directions and parking information
• Speaker bios and session materials
• Post-event surveys and feedback

Print Advertising

Bridge offline and online marketing:

• Magazine and newspaper ads link to landing pages
• Billboard QR codes for mobile-first experiences
• Direct mail campaigns with personalized URLs
• Business cards linking to portfolios or LinkedIn
• Measure print ad effectiveness with scan tracking

Advanced QR Code Strategies

Dynamic QR Codes

While FastTools creates static QR codes (content embedded), consider dynamic codes for campaigns:

• Editable: Change destination URL without reprinting code
• Trackable: Detailed analytics on scans, locations, devices
• A/B testing: Test different destinations
• Expiration: Set codes to expire after campaigns end

Use static codes (from FastTools) for permanent applications; use dynamic codes for tracking campaigns.

QR Code Security

Protect users from malicious QR codes:

• Use HTTPS URLs for secure connections
• Display destination URL near QR code
• Use branded short links for trust
• Test codes regularly to ensure they work
• Avoid QR codes linking to downloads unless trusted

Batch QR Code Generation

When creating multiple QR codes:

1. Prepare list of all URLs or data
2. Use consistent design (colors, size, error correction)
3. Generate codes one at a time
4. Use clear naming convention (product-name-qr.png)
5. Organize files by campaign or category
6. Test all codes before deployment

Testing Your QR Codes

Pre-Launch Testing

Always test before printing or publishing:

• Multiple devices: Test on different phones (iOS, Android)
• Different apps: Native camera app and dedicated QR scanners
• Lighting conditions: Test in bright and dim lighting
• Distances: Scan from expected user distances
• Print test: Print at actual size and scan the physical copy

Common Scanning Issues

If codes don't scan reliably:

• Too small: Increase size (minimum 2cm x 2cm)
• Low contrast: Use darker colors on lighter backgrounds
• Damaged quiet zone: Ensure white border around code
• Complex data: Simplify content or use URL shortener
• Poor printing: Use high-quality printers, avoid inkjet on glossy paper

Measuring QR Code Success

Key Metrics to Track

• Scan rate: Number of scans vs. impressions
• Unique scans: Individual users vs. repeat scans
• Time of day: When are users scanning
• Location: Where scans occur (if using tracking)
• Conversion rate: Scans that lead to desired action

Improving Performance

Optimize based on results:

• A/B test different placements
• Experiment with calls-to-action
• Try different incentives ("Scan for 10% off")
• Optimize landing pages for mobile
• Reduce friction after scan (no login required)
