Design Tips

• Maintain high contrast between foreground and background colors for better scanning
• Test your QR code with multiple devices and scanning apps before distribution
• Keep a minimum quiet zone (white border) around the QR code equal to 4 modules
• Avoid overly complex color schemes that might reduce scannability
• When adding logos, ensure they don't cover more than 20% of the QR code area

Technical Considerations

• Use higher error correction levels (Q or H) when adding logos or customization
• For print materials, use at least 512x512 pixels or SVG format for scalability
• Keep URLs short to reduce QR code complexity and improve scanning speed
• Test QR codes at the actual size they'll be printed to ensure readability

Marketing & Usage

• Include a call-to-action near the QR code explaining what users will get
• Place QR codes in easily accessible locations where people can comfortably scan
• Consider the scanning environment - avoid placing QR codes on curved or reflective surfaces
• For marketing campaigns, track QR code scans using URL shorteners or analytics tools

What is a QR code and how does it work?

A QR (Quick Response) code is a two-dimensional barcode that can store various types of information like URLs, text, contact details, and more. When scanned with a smartphone camera or QR reader app, it instantly provides access to the encoded information. QR codes use error correction to remain readable even if partially damaged.

Is this QR code generator really free?

Yes, our QR code generator is completely free with no hidden costs, subscriptions, or watermarks. You can create unlimited QR codes and download them in multiple formats at no charge. All features are available to all users without any restrictions.

Do the QR codes expire or have scan limits?

No, the QR codes generated by our tool never expire and have no scan limits. Since they're static QR codes, the information is directly encoded in the code itself, making them permanent and always accessible without depending on any server.

Can I track how many times my QR code is scanned?

Our tool generates static QR codes, which means tracking is not built-in. However, if you're creating a URL QR code, you can use URL shorteners like Bitly or analytics platforms to track scans. For dynamic tracking features, you would need a dynamic QR code service.

What's the difference between error correction levels?

Error correction allows QR codes to be readable even when partially damaged or obscured. Level L (Low) offers 7% recovery, M (Medium) 15%, Q (Quartile) 25%, and H (High) 30%. Higher levels create more complex QR codes but provide better reliability, especially when adding logos or using in challenging environments.

What size should I make my QR code for printing?

For print materials, we recommend at least 512x512 pixels or using SVG format for perfect scalability. The minimum recommended print size is 2x2 cm (0.8x0.8 inches), but larger is better. For business cards, aim for 2.5-3 cm. For posters, 5-10 cm or larger depending on the scanning distance.

Can I change the content of a QR code after creating it?

No, static QR codes (like those generated by our tool) have the information permanently encoded and cannot be changed. If you need to update the content, you'll need to generate a new QR code. This is why it's important to verify all information before printing or distributing your QR codes.

Why won't my QR code scan properly?

Common issues include: insufficient contrast between colors, QR code too small, poor lighting conditions, damaged or distorted code, camera focus issues, or overly complex designs. Try increasing the size, improving contrast, using higher error correction, testing with different devices, and ensuring good lighting when scanning.

What file format should I choose?

PNG is best for digital use and general purposes. JPG is good for photographs or when smaller file sizes are needed. SVG is ideal for printing and scaling as it remains sharp at any size. WEBP offers good compression for web use. For professional printing, always choose SVG or high-resolution PNG (1024px or higher).

Is my data secure when using this generator?

Absolutely. Our QR code generator runs entirely in your web browser using client-side JavaScript. No data is sent to our servers or any third party. Everything you enter stays on your device, ensuring complete privacy and security for sensitive information like WiFi passwords or contact details.

Can I add my logo to the QR code?

Logo support is coming soon to our generator. When adding logos, it's important not to cover more than 20% of the QR code area and to use higher error correction levels (Q or H) to maintain scannability. Test thoroughly with multiple devices before using in production.

What's the maximum amount of data I can encode?

QR code capacity varies by content type and error correction level. Generally, you can encode up to about 4,296 alphanumeric characters or 7,089 numeric characters. However, larger data amounts create more complex codes that may be harder to scan. For best results, keep URLs under 300 characters and text under 500 characters.

Do QR codes work without an internet connection?

Scanning QR codes doesn't require internet - the data is directly encoded in the visual pattern. However, what happens after scanning depends on the QR code type. URL codes need internet to load websites, but vCard, WiFi, and text QR codes work completely offline. The generation process also works offline once the page is loaded.
