Frequently Asked Questions
Everything you need to know
What is a QR code generator and how does it work?
A QR code generator is an online tool that creates QR (Quick Response) codes from various types of data like URLs, text, WiFi passwords, contact information, and more. Our free QR code generator works entirely in your browser using advanced algorithms to encode your data into a scannable 2D barcode. Simply enter your content, customize the appearance if desired, and download your QR code in PNG, SVG, or PDF format. The generated QR codes can be scanned by any smartphone camera or QR code reader app to instantly access the encoded information.
What types of data can I encode in QR codes?
Our QR code generator supports multiple data types including website URLs, plain text messages, WiFi network credentials (SSID, password, encryption type), contact information in vCard format (name, phone, email, address), email addresses with pre-filled subject and body, phone numbers for direct calling, SMS messages with pre-written text, geolocation coordinates, calendar events, and payment information. Each data type is optimized for the best scanning experience, making our tool perfect for business cards, marketing materials, restaurant menus, product packaging, event tickets, and digital signage.
Can I customize the appearance of my QR codes?
Yes! Our free QR code maker offers extensive customization options. You can choose custom foreground and background colors to match your brand identity, adjust the QR code size for different applications (from small business cards to large posters), select error correction levels (Low, Medium, Quartile, High) to balance data capacity with scanning reliability, and download in multiple formats including PNG for web use, SVG for scalable vector graphics, and PDF for professional printing. Custom colored QR codes can increase brand recognition while maintaining full scannability when designed with sufficient contrast.
Are there any limits on QR code generation?
No limits! Our QR code generator is completely free with unlimited QR code creation. You can generate as many QR codes as you need for personal or commercial use without any restrictions, subscriptions, or hidden costs. The only technical limitation is the data capacity of QR codes themselves, which varies based on error correction level and data type. Numeric data can store up to 7,089 characters, alphanumeric data up to 4,296 characters, and binary data up to 2,953 bytes. For most use cases like URLs, WiFi passwords, and contact cards, these limits are more than sufficient.
Is my data secure when generating QR codes?
Absolutely! Privacy and security are our top priorities. All QR code generation happens directly in your browser using client-side JavaScript. Your data never leaves your device, is not sent to any server, and is not stored anywhere. This ensures complete privacy and security for sensitive information like WiFi passwords, contact details, payment information, or confidential URLs. Unlike cloud-based QR code generators that may track or store your data, our tool processes everything locally, making it safe for personal, business, and enterprise use.
What is the difference between static and dynamic QR codes?
Static QR codes contain the actual data embedded directly in the code pattern, meaning the encoded information is permanent and cannot be changed after creation. Our generator creates static QR codes that work forever without requiring any server or subscription. Dynamic QR codes use a short redirect URL that points to a server where the actual content is stored, allowing you to update the destination without reprinting the QR code. While dynamic QR codes offer flexibility, they require ongoing service subscriptions and stop working if the service shuts down. Static QR codes are perfect for permanent information like business cards, product labels, and printed materials where reliability is crucial.
How do I create a WiFi QR code for easy network sharing?
Creating a WiFi QR code is simple with our generator. Select the WiFi option, enter your network name (SSID), password, and choose your security type (WPA/WPA2, WEP, or no encryption for open networks). The generator creates a QR code that, when scanned, automatically prompts users to join your WiFi network without manually typing the password. This is perfect for homes, offices, cafes, hotels, and events where you want to provide easy WiFi access to guests. The QR code can be printed, displayed on screens, or added to welcome materials for convenient network sharing.
What file formats can I download my QR codes in?
Our QR code generator supports three professional formats: PNG (Portable Network Graphics) for digital use on websites, social media, emails, and presentations with transparent backgrounds and customizable resolution; SVG (Scalable Vector Graphics) for infinite scalability without quality loss, perfect for professional printing, signage, and graphic design work; and PDF for high-quality printing on business cards, flyers, posters, and professional documents. PNG is best for web and screen use, SVG for print materials that need to scale to any size, and PDF for professional printing and document integration. All formats maintain QR code scannability and support custom colors.
What is error correction and which level should I choose?
Error correction allows QR codes to remain scannable even when partially damaged, dirty, or obscured. There are four levels: Low (7% recovery) for clean digital displays, Medium (15% recovery) for general use and standard printing, Quartile (25% recovery) for outdoor use or small print sizes, and High (30% recovery) for extreme conditions or when adding logos to QR codes. Higher error correction means more redundant data, resulting in denser QR codes with lower data capacity. For most applications, Medium is recommended. Use High if you plan to add a logo to the center or expect the code to get damaged or dirty over time.
Can I use QR codes for commercial purposes?
Yes! QR codes generated with our tool are completely free for both personal and commercial use with no licensing fees or restrictions. You can use them on business cards, product packaging, marketing materials, advertisements, restaurant menus, retail displays, event tickets, invoices, and any other commercial application. QR code technology is an open standard maintained by ISO (International Organization for Standardization), meaning no one owns the underlying patent rights. Our generator creates standard-compliant QR codes that work with all QR code readers and smartphone cameras worldwide.
How do I ensure my QR code works properly?
To ensure QR code reliability, follow these best practices: Test your QR code with multiple devices (iPhone, Android) and different QR code reader apps before printing or publishing. Maintain high contrast between foreground and background colors (dark on light works best). Ensure adequate quiet zone (white space) around the QR code - at least 4 modules (squares) wide. Use appropriate size - minimum 2x2 cm (0.8x0.8 inches) for print, larger for viewing from distance. Choose appropriate error correction level based on use case. Avoid using the QR code on reflective, curved, or textured surfaces that might interfere with scanning. Print at high resolution (300 DPI minimum) for professional results.
Do QR codes expire or stop working?
Static QR codes generated by our tool never expire and work forever without any ongoing costs or subscriptions. Once created, the data is permanently encoded in the QR code pattern itself, not stored on any server. As long as the physical QR code remains intact and scannable, it will continue to function indefinitely. This makes static QR codes ideal for permanent applications like product labels, business cards, gravestones, plaques, and historical markers. Unlike dynamic QR codes that rely on external services that can shut down or require subscription renewals, our static QR codes provide true permanence and reliability.
