Everything you need to know about QR codes, our generator, and best practices. Can't find your answer? Contact us and we'll be happy to help!
QR (Quick Response) codes are two-dimensional barcodes that can store various types of information such as URLs, contact details, WiFi credentials, or plain text. They were invented in 1994 by Denso Wave for the automotive industry but have since become ubiquitous for marketing, payments, and information sharing.
Unlike traditional barcodes that can only hold about 20 characters, QR codes can store up to 4,296 alphanumeric characters, making them incredibly versatile for modern applications.
Most modern smartphones (iPhone iOS 11+ and Android 9+) have built-in QR code scanning in their camera apps:
Yes, absolutely! Our QR code generator is 100% free to use with no hidden costs. You can:
We're committed to keeping our core service free forever. We sustain the platform through ethical advertising and optional user support.
No signup is required! You can generate and download QR codes instantly without creating an account. We believe in making our tools accessible to everyone without barriers.
However, if we add features like QR code history or campaign management in the future, those may require optional account creation.
Our generator supports a wide range of QR code types:
Static QR codes (what we generate) last forever! Once you download the QR code image, it will continue to work indefinitely. The data is encoded directly into the image, so it doesn't rely on any external service or server.
Important: This is different from "dynamic" QR codes offered by some paid services. Dynamic codes contain a short URL that redirects to your content, allowing you to change the destination without regenerating the code - but they require an ongoing subscription and will stop working if the service is discontinued.
Yes! We offer extensive customization options:
Pro tip: We use error correction level H (highest) when you add a logo, ensuring your QR code remains scannable even with the logo covering up to 30% of the code.
The resolution you need depends on your print size and viewing distance:
Golden Rule: For every 10 feet of scanning distance, increase the QR code size by 1 inch. For example, a billboard scanned from 50 feet away should have a QR code at least 5 inches in size.
Yes, absolutely. We take privacy very seriously:
GDPR & CCPA Compliant: We comply with international privacy regulations including GDPR (Europe) and CCPA (California). We collect minimal analytics to improve our service, but never personal or identifying information.
Absolutely! You can use the QR codes you generate for any purpose, including:
There are no usage restrictions, no attribution required, and no licensing fees. The QR codes you create are yours to use as you wish.
We collect minimal anonymous analytics to improve our service, but we do not track, analyze, or store the actual QR codes you create or their content. Specifically:
The minimum recommended size is 2cm x 2cm (0.8" x 0.8") for close-range scanning (like business cards or flyers). However, the optimal size depends on several factors:
Size Guidelines by Use Case:
Pro tip: Test your QR code at the actual size it will be printed and from the expected scanning distance before mass production.
If your QR code isn't scanning well, check these common issues:
Currently, our free tool focuses on creating individual high-quality QR codes. Each code is optimized for your specific needs with custom branding and design options.
Coming Soon: We're working on a bulk generation feature for users who need to create multiple QR codes at once (e.g., for product labeling or event ticketing). Stay tuned!
