What is a QR Code?
A QR code (Quick Response code) is a two-dimensional barcode that stores information in a pattern of black squares on a white background. Originally developed in Japan for tracking automotive parts, QR codes have become ubiquitous in marketing, payments, and information sharing. When scanned with a smartphone camera, QR codes instantly direct users to websites, display contact information, connect to WiFi networks, or trigger other digital actions.
Our free QR code generator creates high-quality codes that work reliably across all devices and scanning applications. Unlike many online generators, we do not add watermarks or tracking parameters to your QR codes. The codes you create are completely yours to use for personal or commercial purposes without any restrictions.
QR codes support error correction, which means they can still be scanned even when partially damaged or obscured. Our generator offers multiple error correction levels: Low (7% recovery), Medium (15% recovery), Quartile (25% recovery), and High (30% recovery). Higher error correction allows for more damage resistance but results in a denser, more complex pattern.
Common QR Code Uses for Businesses
Marketing and Advertising
Place QR codes on print materials like business cards, flyers, posters, and product packaging to connect customers directly to your website, landing pages, or promotional offers. QR codes bridge the gap between physical marketing and digital engagement.
Restaurant Menus
Display QR codes on table tents or signage to let diners view digital menus on their smartphones. This approach reduces printing costs, allows for easy menu updates, and provides a contactless experience that many customers now prefer.
WiFi Network Sharing
Generate WiFi QR codes that allow guests to connect to your network instantly without manually entering passwords. Perfect for offices, retail stores, hotels, and events where you want to provide convenient internet access.
Event Management
Use QR codes for event registration, ticket validation, and attendee check-in. Link to event schedules, speaker bios, or interactive maps to enhance the attendee experience at conferences, trade shows, and community events.
QR Code Best Practices
Test Before Printing
Always scan your QR code with multiple devices and apps before committing to print. Verify that the destination URL is correct and that the code scans reliably at the intended size.
Maintain Adequate Size
QR codes should be at least 1 inch (2.5 cm) square for reliable scanning from a typical smartphone distance. For codes that need to be scanned from farther away, such as on billboards or posters, increase the size proportionally.
Ensure Sufficient Contrast
QR codes need strong contrast between the pattern and background to scan reliably. Dark patterns on light backgrounds work best. Avoid placing codes on busy backgrounds or using colors that do not provide adequate contrast.
Include a Call to Action
Always tell users what to expect when they scan your QR code. Add text like "Scan for menu", "Scan to connect to WiFi", or "Scan for special offer" near the code to encourage scanning and set expectations.
