Static vs Dynamic QR Codes — quick decision

Static QR Codes

Encoded URL is permanent. Best for single-use or unchanging destinations.

• No analytics
• No editing — reprint to change
• Simple & free

Dynamic QR Codes (Recommended for businesses)

Uses a redirect/tracking layer so you can edit the destination and track every scan.

• Editable destination (no reprint)
• Full analytics: scans, devices, location, timestamps
• UTM support, campaign A/B testing

Decision rule: if you run marketing or print materials, use Dynamic QR. Static only when the link will never change and tracking is unnecessary.

Step-by-step: Create a QR Code (practical)

1. Step 1 — Open the QR Code Generator

   Navigate to https://theshortener.com/qr-codes. You’ll see options for Static and Dynamic QR codes, branding options, and download formats.

2. Step 2 — Enter the destination

   Choose the content type: URL, PDF, vCard, Google Maps, WhatsApp, or Wi-Fi credentials. Paste the destination into the field.

3. Step 3 — Select Static or Dynamic

   Select Dynamic for editable links and analytics. Choose Static if the link is permanent and you don't need tracking.

4. Step 4 — Customize design

   Options typically include:

   • Logo upload (keep it small: 20–30% of QR inner area)
   • Colors for foreground/background
   • Frame and CTA label
   • Custom eye and matrix patterns

   

5. Step 5 — Generate & preview

   Click Generate. Preview scanning behavior on a phone and in black/white to confirm contrast.

6. Step 6 — Export print-ready files

   Download as SVG for printing and PNG for digital use. Prefer SVG for posters, packaging, and any large-format print.

7. Step 7 — Test everywhere

   Test on iOS and Android, at different distances and lighting conditions. Print a sample and scan it in the environment where it will be used.

Tip: keep a quiet zone (margin) around the QR — at least the width of one module (the smallest square) or 4mm on print.

Tracking & analytics (dynamic QR only)

When you choose dynamic QR codes, The Shortener collects:

• Total & unique scans
• Device type (mobile/desktop), OS
• Geographic data (country, city where available)
• Timestamps & referrers
• UTM parameter attribution

Use this data to optimize placement, messaging, and conversions across campaigns.

Best practices for high scan rates

• Keep contrast high (dark QR on light background is safest)
• Minimum recommended size: 2cm × 2cm at close range; scale with viewing distance
• Leave a quiet zone around the code
• Use an explicit CTA near the QR: e.g., “Scan to view menu”
• Prefer SVG for print to avoid pixelation

Common mistakes that break scanning

• Low resolution PNGs for large prints
• Too-large logo covering critical modules
• Busy background images behind the QR
• Insufficient contrast or inverted color without testing
• Not testing before large print runs
