Frequently Asked Questions About QR Codes & Barcodes
What is a QR code and how does it work?
A QR (Quick Response) code is a two-dimensional barcode that stores information in a grid pattern of black and white squares. Our generator creates QR codes that can encode URLs, text, contact information, WiFi credentials, and more. When scanned with a smartphone camera or QR reader, the code instantly reveals the encoded information.
Our QR codes follow ISO/IEC 18004 standards and include built-in error correction, allowing them to be scanned even if partially damaged or obscured. The codes work universally with all standard QR code readers and smartphone cameras across iOS and Android devices.
How reliable are the QR codes generated by your platform?
Our QR codes meet ISO/IEC 18004 international standards and have been tested across hundreds of devices and scanning applications. They feature advanced error correction (up to 30% recovery) ensuring reliable scanning even in challenging conditions like poor lighting, slight damage, or at various distances.
Unlike many online generators, we optimize every code for maximum compatibility and readability. Our codes are used by Fortune 500 companies, small businesses, and individuals worldwide with a 99.9% successful scan rate when printed or displayed properly.
How long does it take to create a QR code?
Creating a QR code is instant! Simply enter your content (URL, text, contact info, etc.), customize the design if desired, and your code is generated in real-time. The entire process typically takes less than 30 seconds from start to download.
For users who need multiple codes, our bulk generation feature can create hundreds of unique QR codes simultaneously, perfect for events, inventory management, or product catalogs. Even large batches are processed within seconds.
What customization options are available for QR codes?
You have complete control over your QR code's appearance! Customize foreground and background colors, add your logo or brand image, choose from various frame styles, adjust error correction levels (L, M, Q, H), and set the output size from 100px to 4K resolution.
All customizations maintain scannability - our preview tool shows real-time feedback to ensure your personalized QR code remains fully functional. You can create codes that perfectly match your brand identity while maintaining professional quality and reliability.
Is the QR code generator available in multiple languages?
Yes, our platform supports 15+ languages including English, Spanish, French, German, Chinese, Arabic, and many others. The interface is fully localized, making it easy to create QR codes regardless of your preferred language or location.
QR codes themselves are universal and language-independent - a code created in any language will scan perfectly anywhere in the world. The content you encode (like URLs or text) can be in any language or character set, including Unicode.
