QR (Quick Response) codes are two-dimensional barcodes that can store various types of information. When scanned with a smartphone camera, they instantly direct users to websites, contact information, WiFi networks, and more. QR codes have become essential for businesses, marketers, and individuals looking to bridge the gap between physical and digital experiences.
QR codes encode data in a grid of black and white squares. The pattern includes:
QR codes have numerous practical applications across industries. Here are the most popular ways businesses and individuals use QR codes:
| Use Case | Description | Key Benefit |
|---|---|---|
| Business Cards | Add QR code linking to LinkedIn, portfolio, or vCard | Instant digital contact sharing |
| Restaurant Menus | Link to digital menu PDF or online ordering page | Contactless, updatable menus |
| Marketing Flyers | Track campaign engagement with unique QR codes | Measure offline marketing ROI |
| Event Tickets | QR codes for event check-in and registration | Fast, paperless verification |
| WiFi Sharing | Allow guests to connect without sharing password | Convenient, secure access |
| Product Packaging | Link to product info, manuals, or support pages | Enhanced customer experience |
| Resume/Portfolio | Direct recruiters to online portfolio or LinkedIn | Stand out from other candidates |
| Payment Collection | UPI/PayPal payment QR codes for transactions | Easy contactless payments |
QR codes can encode different types of data, each triggering a specific action when scanned:
| Type | Format | What Happens When Scanned |
|---|---|---|
| URL | https://example.com | Links to any website or web page |
| Text | Plain text message | Any text content up to ~2000 characters |
| mailto:[email protected] | Opens email app with address pre-filled | |
| Phone | tel:+911234567890 | Opens phone dialer with number ready |
| WiFi | WIFI:S:SSID;T:WPA;P:password;; | Auto-connects to WiFi network |
| SMS | sms:+911234567890?body=Hello | Opens SMS with number and message |
| vCard | BEGIN:VCARD...END:VCARD | Complete contact card with details |
| Location | geo:latitude,longitude | Opens maps to specific location |

To ensure your QR codes scan reliably and look professional, follow these design tips:
Most modern smartphones can scan QR codes directly through the camera app. Simply open your camera, point it at the QR code, and a notification will appear with the linked content. For older phones, you may need to download a QR scanner app. Both Android (Google Lens) and iOS have built-in QR scanning capabilities.
Yes, our QR code generator is completely free to use. You can create unlimited QR codes for URLs, text, email, phone, and WiFi without any cost or signup. The generated codes are high-quality and can be used for both personal and commercial purposes.
Static QR codes (like the ones we generate) never expire. The data is encoded directly in the pattern. However, if you create a QR code linking to a website and that website goes down, the QR code won't work. Dynamic QR codes (offered by paid services) can be edited after creation but may have expiration dates.
For reliable scanning, QR codes should be at least 2cm x 2cm (0.8 x 0.8 inches)for close-range scanning. For posters or signs viewed from a distance, use larger sizes. A good rule of thumb: the scanning distance should be about 10 times the QR code width. A 3cm QR code can be scanned from about 30cm away.
Our free tool generates standard black and white QR codes. For custom colors, logos, or designs, you can use the generated QR code as a base and edit it in design software. Just ensure you maintain enough contrast and don't cover the position markers (corner squares).
A standard QR code can store up to 3,000 alphanumeric charactersor about 7,000 numeric digits. However, more data means a more complex (and harder to scan) code. For best results, keep URLs short using URL shorteners if needed. WiFi QR codes typically work well with standard password lengths.
QR codes themselves are not inherently secure or insecure - they simply encode data. However, malicious QR codes can link to phishing sites or malware. Always verify the destination URL before clicking. For sensitive information like WiFi passwords, our codes don't store data on any server - the info is encoded directly in the image.
Select the "WiFi" tab in our generator, enter your network name (SSID), password, and security type (usually WPA/WPA2). The generated QR code, when scanned, will automatically connect the device to your WiFi network without manually entering the password. This is perfect for offices, cafes, and home guests.
Static QR codes (like ours) don't have built-in tracking. To track scans, you can: 1) Use a URL shortener with analytics (like Bitly) before generating the QR code, 2) Link to a page with Google Analytics, or 3) Use a paid dynamic QR code service that provides scan analytics including location, device, and time data.
Static QR codes (what we generate) encode data directly and cannot be changed after creation. Dynamic QR codes link to a redirect URL that can be changed later. Static codes are free and permanent; dynamic codes require a subscription but offer flexibility and analytics.
