What is a QR Code?
A QR code (Quick Response code) is a two-dimensional barcode that can be scanned by any smartphone camera to instantly open a URL, display contact information, connect to WiFi, send a WhatsApp message, or perform dozens of other actions. QR codes became mainstream in India with the UPI payment revolution and are now used in print marketing, restaurant menus, business cards, event tickets, product packaging, and digital campaigns.
Unlike traditional barcodes that store only 20 digits, a QR code can store up to 4,296 alphanumeric characters — enough for a full web address, email, or contact card.
Types of QR Codes You Can Create
- Website URL QR Code: Most common type. Links directly to any webpage. Perfect for business cards, banners, and flyers.
- vCard QR Code: Encodes your full contact information. When scanned, it prompts the user to save your contact directly to their phone.
- WhatsApp QR Code: Opens a WhatsApp chat with a pre-filled message. Great for customer support and lead generation.
- WiFi QR Code: Lets guests connect to WiFi by scanning — no password needed. Ideal for cafes, hotels, and offices.
- Email QR Code: Opens the phone's email client with the recipient pre-filled.
- Phone QR Code: Initiates a call when scanned.
- Text QR Code: Displays any plain text message when scanned.
QR Codes for Digital Marketing & SEO
QR codes bridge offline and online marketing, creating measurable touchpoints in print campaigns. Use QR codes on business cards to link to your LinkedIn profile, on product packaging to link to review pages, in magazine ads to track campaign ROI, and on restaurant menus to link to Google My Business for reviews. Adding UTM parameters to your URL before generating the QR code lets you track scans in Google Analytics.
Best Practices for QR Codes
- Always test your QR code on multiple devices before printing.
- Set error correction to "High" (30%) for QR codes that will be printed — allows the code to work even if partially damaged.
- Ensure sufficient contrast between foreground and background colours. Never use light-on-light or dark-on-dark.
- Minimum print size: 2.5 cm × 2.5 cm for reliable scanning.
- Always provide a brief call-to-action near the QR code (e.g., "Scan to visit our website").
- For URLs, use a URL shortener so the QR code is less complex and easier to scan.
Frequently Asked Questions
Are QR codes free to create and use? +
Yes. Our QR Code Generator is completely free with no limits, no watermarks, and no expiry. Static QR codes (like URL codes) work forever — they don't need a server and never expire.
What is the difference between static and dynamic QR codes? +
Static QR codes contain the data directly in the code and cannot be changed after creation. Dynamic QR codes point to a redirect URL that can be updated at any time. Our generator creates static codes — free and permanent.
What size should a QR code be for print? +
The minimum recommended size is 2.5 cm × 2.5 cm (roughly 1 inch) for print materials. For large formats like banners and posters, generate a 600px QR code and scale up using the SVG format for sharp results at any size.
Can I customise QR code colors? +
Yes. Use our color pickers to choose any foreground and background color. Ensure there is strong contrast (dark foreground on light background) for reliable scanning. Avoid low-contrast combinations like yellow-on-white.
What image format should I download? +
Download PNG for digital use (websites, email, social media). Download SVG for print — it's vector-based and scales to any size without pixelation.
Do QR codes expire? +
Static QR codes (like those created here) never expire. As long as the destination URL is active, the QR code will work. Dynamic QR codes from third-party services may expire if you stop paying.
